Read entire post: Learn how to increase GVM and Offroad Performance on your Landcruiser 70 Series

Our latest addition here at All Four x 4 Spares is one of those premium products that will dramatically increase offroad performance in a vehicle. This vehicle is not just any vehicle..when we are talking about the Landcruiser 70 Series 


We are very proud to bring on board:


Ultimate Dana 60                                                                                                                     

A Premium Rear Axle Full Floating solutiondana_logo

for LandCruiser 70 Series that improves:

  • Drive-ability
  • Higher axle load capacity
  • and increases durability



This Ultimate Dana 60 is the biggest, strongest Dana 60 axle ever built, incorporating upgrades demanded by off-roaders



Check Dana 60's Video to learn more:





This Axle Kit is pretty cool since the original axle centre is offset with 95mm wider overall track


and while retaining the full-float design, the vehicle weight is carried by housing for greater load-carrying ability.


Previously vehicle users resorted to fitting illegal wheel spacers or had their original axle extensively modified by workshops to overcome the narrower rear track width. 


Dana is now able to provide a fully tested alternative backed by Dana’s extensive engineering team and supported with a 12 month / 30,000 Km warranty. 


An excellent example of ‘Aussie’ design, manufacturing expertise and capability”.


On top of the new axle include 95mm increased rear track width, some other major features are: increased lubrication capacity, higher axle load capacity, heavy-duty suspension bracketry, heavy-duty cover plate, plug and play E-Locker. The design cleverly allows retention of the original equipment brakes, hubs and wheels.  



Design inclusions:  

  • Retains the full-float design; vehicle weight is carried by housing for greater load-carrying ability 
  • Original axle centre offset with 95mm wider overall track – no wheel spacers required 
  • 30 spline larger diameter forged 1541 steel alloy axle shafts 
  • Selectable electronic locking differential – genuine Harrop Eaton E-Locker™ 
  • Heavy duty 9¾” (248 mm) ring gear 
  • Massive 3½” (89.9mm) outside diameter 0.390″ (10mm) wall thickness axle tubes 
  • Heavy-duty suspension brackets – ready for your heavy-duty suspension upgrade 
  • Nodular iron diff cover

This is HOW you restore a 1978 Landcruiser 40 Series Shorty (Part 1)

Read entire post: This is HOW you restore a 1978 Landcruiser 40 Series Shorty (Part 1)








For our friends at Brown Davis, 2018 will be a special year. Infact 2018 will be the 40th anniversary of Brown Davis Automotive or more simply "Brown Davis" how we got to know them.


For those few (and there's never shortage of these people) that lived under a rock for the past 40 years, Brown Davis is a top brand manufacturer of Long Range Fuel Tanks, Underbody Protections, Tail Gate Seals etc for over 200+ 4x4 models vehicles as well as Australian and US military, mining vehicles, trucks, carpet cleaning vans and motorhomes. (All Four x 4 Spares is a proud Brown Davis stockist of long range fuel tanks and underbody protections for over 100+ 4x4 vehicles, see our vast range here)


40 years ago David Brown founded Brown Davis Automotive in Melbourne, Australia. Back to the very first days, in order to help Rod Stephen Racing to get those extra laps needed to go around Mount Panorama in Bathurst, David created a first prototype of light weight aluminium fuel tank. Shortly after, this led to a close friend wanting the same for his Landcruiser 40 Series to get him all the way to Cape York Peninsula, right at the tip. Order after order and Brown Davis long range fuel tanks was born.


For this 40th anniversary, the Brown Davis Team wanted to celebrate it in a very special meaningful restoring a Toyota Landcruiser 40 Series Shorty from 1978. And they partnered up with some 4wd industry pioneers.




In the summer 2018, the Brown Davis Team will be making a trip through the Victorian high country with the newly restored 40 Series and other awesome old 4wd. Leading this trip will be  Alan Johnson from Piranha Offroad in his 60 Series Land Cruiser, a true 4wd veteran with great knowdledge of the area. 




  • For the body and chassis they used an early model 40 series. The chassis is high tensile steel riveted together that cannot be welded along the ladder frame, only at each end past the last riveted cross members. All new brackets & cross members bolted on.
  • Front and rear assemblies were taken from a 60 Series with stronger & bigger brakes



  • V8 engine from a Chevrolet 350 (mounts made to suit)
  • Gearbox from a 5 speed Toyota 75 series (cross member made to suit) with marks adaptor kit to match engine.
  • Master cylinder and new H/D clutch from a 60 series 
  • New longer build tail shafts (100mm more compared to standard ones)






  • Front springs reversed in order to get the fixed eye at the front (less axel steer on bump) and the axel was moved forward 50mm.
  • To align the tail shaft and reduce vibration, they changed the diff pinion angle and gave 3.5 deg positive caster to improve steering stability at speed
  • The Rear Springs were moved back on side rails of the chassis of 150mm ( total wheelbase extended by 200mm)
  • Front & rear long travel shocks were taken from auUsed 60 series and mounts on chassis made to suit.









  • In order to match the new axel position they moved the Front section of the body 50mm forward and the rear section 50mm back
  • To match the outer tyre & wheel width they extended the Front guards 70mm wider 





Brand New wheels + David Brown himself...





They made the mount to sit the rear bar higher and further from the body




And a New Roll Cage




More articles will be posted as they keep working on this restoration so stay tuned!

Drive a Common Rail Diesel? You should probably read this!

Read entire post: Drive a Common Rail Diesel? You should probably read this!




Why your common rail needs a catch can and fuel pre-filter


The modern diesel engine is a pretty awesome thing. Gone are the days of slow, rough and belching diesels that were tough to live with; these days diesel donks are powerful, efficient and quiet. On the flip side, they are much more complex than the good old days, and have some pretty tricky engineering that you should know about:



High-Pressure Fuel Injection



Once upon a time, the fuel pump setup on a diesel was a fairly simple affair. There was a lift pump, which fed an injector pump. Then, the injector pump sorted out the timing and fuel dose for each injector. You can see where they get their reputation for being so simple.

These days, it’s a bit different. Firstly, you’ve got computers on-board that take care of the injection timing, no need for an injector pump for timing any more. What a common rail system does need, however, is fuel at a very high pressure.


Modern diesels use advanced pumps that develop up to 3,000psi of pressure in the fuel system. This feeds a reservoir right up near your injectors, called a ‘common rail’. It looks like a rail, and supplies your injectors with high-pressure fuel. The only problems with common rail are that they have much lower tolerances to wear and dirt than older system, and are only happy with clean fuel.


Trick injectors



Injectors, controlled electronically and individually by the ECU, can use this ready supply of high-pressure diesel to inject a fine mist of fuel at the perfect moment. This keeps your diesel engine quiet, powerful and efficient.


Common rail injectors are able to provide incredibly precise and controlled fuel injections, in terms of amount and spray pattern. Modern injectors will often go through multiple, different injections for each combustion cycle, all in the quest for cleanliness and efficiency. The injection is controlled by very accurate and delicate electromagnets (magnets that are controlled by an electric current) or piezoelectric (crystalline materials that change size from electric current).


Keep it clean


If you want to take good care of your fuel system, there is one simple solution: keeping your fuel clean. Recently introduced Australian Standards keeps a fairly high minimum requirement for fuel these days, but your biggest enemy is contaminants.





Stop dirt and water ruining your fuel system with two simple tips:


1: Change your factory fuel filter regularly, and only use good quality filters.


2: Install an additional fuel filter into your system, for extra protection. This will take the stress off your factory filter, and give your pump and injectors the best chance of a long, happy life.






More pressure


And of course, you can’t forget the turbocharger hanging off the side. Using spent exhaust gasses; the turbo compresses the air destined for the combustion chamber. Denser air means you can squeeze some extra fuel in, and make a bigger bang overall. Bigger bang equals more power.


Turbocharging is the main tool used to get big power out of relatively smaller modern power plants. At the end of the day, the engine is working a bit harder with a turbo to make that extra power, but there is one trick you can do it help out: Fit a catch can.


Fit an oil catch can.





The oil catch can is a smart, simple device that keeps your engine running at it’s maximum. The engine crankcase needs to breath, especially if it’s a hard-working turbo diesel. This air, laden with oil mist, can’t be vented to the atmosphere. It has to be reintroduced back into the engine.


The problem with this is that as this oily air circulates through your EGR, intercooler, turbo, intake manifold and piping, it’s going to leave oil and carbon behind, which will slowly build up and reduce your engine’s power and efficiency. EGRs can be completely blocked with carbon, and intercoolers can literally fill with oil.


A properly installed catch can will intercept oil and crap in the crankcase gasses, filtering them out before they get reintroduced back to the engine. This keeps your engine cleaner overall, and running at it’s optimum performance. 


One fine example is Catch Can Pro from Flashlube - the answer to carbon build up in modern engines

GVM / BTC Upgrades – what are they and why are they important?

Read entire post: GVM / BTC Upgrades – what are they and why are they important?



There has been a lot of talk lately about GVM upgrades and BTC upgrades. If you found yourself googling gvm meaning, what is gvm, what does gvm mean, gvm weight, gcm meaning, gvm weight v tare weight, what is gross vehicle mass and the list can go on forever, are not alone!


Let’s clear up some of the confusion with terminology and explain some of the options we have available here at All Four x 4 Spares



First let's define them:



GVM: Gross Vehicle Mass

The GVM of a motor vehicle means the maximum loaded mass of the vehicle


GCM: Gross Combination Mass

The GCM of a motor vehicle means the greatest possible sum of the maximum loaded mass of the motor vehicle and of any vehicles that may lawfully be towed by it at one time


BTC: Braked Towing Capacity

The BTC of a vehicle is the maximum loaded mass of a braked trailer/caravan which can be towed by the vehicle




Where maximum loaded mass is mentioned above this includes accessories (bullbar, roof racks, long range fuel tanks, recovery gear, custom tradesman rear tray, etc), tools, passengers, camping gear, food, fuel, water and equipment – everything!




Why do we need to think about these factors?


Most people would understand there are weight limits with regards to how much your vehicle can carry and tow. The average driver in the average situation will not approach these limits, however it is quite easy to approach or exceed them


Vehicle manufacturers don’t always play it straight when quoting vehicle weights. They are trying to sell cars and so will quote the most favourable numbers they can to sell their vehicles. Often the manufacturers stated unladen weight does not take into account simple things like dealer fitted accessories and a full fuel load which individually may not weigh a great deal, but combined can add up


Add to this a couple of aftermarket accessories like a winch, long range fuel tank, roof rack etc and you can very quickly approach or even exceed the GVM


Got room for 5 adults? – that alone could increase the mass of the vehicle by half a ton!


Trade vehicles can also be particularly susceptible to this when adding things like custom cabinet style tray backs on a cab chassis vehicle, and tools – they can add up very quickly. Throw some building supplies in the mix (couple of bags of sand and cement wouldn’t hurt, would it?) and again you could easily find yourself exceeding GVM


Add these factors together and you would be surprised by how many vehicles driving on the road today that would be very close to, or exceeding, their GVM




So what?


Well, there are good reasons GVM limits exists, and just as good a reasons to have it increased on your vehicle OFFICIALLY!


Most important is safe and controllable vehicle handling, especially in emergency situations. Ever tried to change lanes in a hurry with a loaded-up vehicle? Especially if you have something on the roof, the lurch and sway can range from scary to outright dangerous


While investigating a claim, insurance companies often look at vehicle loading to determine if there have been any breaches in legislation. If it means they won’t need to pay out a claim they are going to examine it closely, and they do!


Manage a fleet of vehicles for your company? To protect businesses and managers from breaches of occupational health and safety a GVM increase can provide that bit of extra cover for situations that otherwise maybe pushing the limits.


Some employees don’t always do the right thing, so again having a margin of error to allow for instances of overloading can provide a safety factor which wouldn’t ordinarily exist


The RMS (here in NSW) and State Police actively monitor our roads and highways and overloaded vehicles are on their radar. There are stories doing the rounds which describe holiday makers being pulled over for a weight check only to find their vehicle is over the manufacturers GVM limit and are unable to continue their journey unless a tow is arranged or if they leave some heavier possessions on the side of the road to reduce weight




Our GVM upgrade partner - Lovells Springs - holds Compliance Plate Approvals as a Second Stage Manufacturer (SSM) of GVM upgrades for several makes of vehicle including:


  • Toyota 
  • Nissan 
  • Ford 
  • Isuzu 
  • Mazda


They are steadily expanding the range of vehicles for which they offer this upgrade.


But a comprensive vehicle list can be found in our Lovell Spring promotional page, take a look at it here


Lovells Springs logo






All Four x 4 Spares has been assessed by the SSM and we have been registered with the Federal Department of Transport and Regional Services as a Production Facility.


This allows us to supply, fit, obtain engineering approval and submit paperwork to the relevant agencies to have your vehicles GVM officially increased.

Apart from the compliance plate, placards/decals and paperwork each Lovells suspension kit consists of a set of heavy duty springs and long travel gas shock absorbers. Additional components vary from vehicle to vehicle
















Some vehicles require additional parts to comply with various ADR’s – like mudflaps or a handbrake cable extension bracket – which will be included in the kit if required.


Components may include polyurethane suspension bush kit, hi-tensile u-bolts, greaseable shackles, greaseable shackle pins, brake load proportioning valve spacer, handbrake cable extension bracket, ABS spacer kit and mudflaps


Of course, all of the load ratings above apply equally to the towed vehicle (trailer, caravan etc) too, which leads to…..




BTC Upgrades


A Braked Towing Capacity upgrade is what you need if you have a large caravan or trailer


Small vans can weigh 1000-2000kg. When towed with an appropriate vehicle you have a reasonable amount of wiggle room for loading


Large vans even when empty can weigh 2000-3000kg, some even more. Even with a large 4x4 you will be approaching the limit with only a minimal amount of equipment on board


Think again about the amount of gear to be loaded – food, cooking utensils, sleeping gear, clothes, camping equipment, batteries, generator, gas cylinders, air conditioner. Got water tanks? 1L of water weighs 1kg, so a couple of 100L tanks…


Earlier this year - during January 2017 - Victorian Police conducted Operation Roadhouse, part of which involved pulling over and weighing caravans. 41 of the 70 caravans weighed were found to be overweight in some respect. This was treated by the police as an educational exercise and no fines were issued in relation to weight, but the figures tell a story


As a side note there were two fines issued although both were for unsuitable towing mirrors. This is also something we can help with in our accessories department @ All Four x 4 Offroad


Currently available for a small range of vehicles Lovells offer braked towing capacity upgrades. Unfortunately, the nature of the beast with the level of testing and associated paperwork required to sell a government approved vehicle upgrade, some patience is required for more vehicles to gain approval


We currently have BTC upgrades available in two levels (Stage 1 and 2) for 200 Series Landcruiser and 150 Series Prado. GVM upgrade must be conducted before BTC can be certified:

Stage 2 BTC - must have GVM fitted first

Table 2



The most significant difference - aside from the towed weight increase - between Stage 1 and Stage 2 BTC upgrade is the ajustability of the supplied hitch.


The Stage 2 kit hitch allows the tow ball height to be adjusted while the towed vehicle is attached which makes levelling of the tow rig a breeze.


For the Stage 1 kit the ball height must either be calculated and adjusted before connecting or requires the towed vehicle to be connected, then removed and adjusted as required.





The components vary depending on vehicle, but typically include:


  • heavy duty tow bar,
  • heavy duty premium auto coupler hitch (consists of offroad hitch and matching tow pillar),
  • weight distribution hitch,
  • compliance plate,
  • instruction manual,
  • fitting instructions and decals




Federal V’s State Compliance

Are you about to purchase a brand-new vehicle and are planning on a caravan road trip of a lifetime?

Are you a tradesman about to renew your work truck with something shiny off the showroom floor?




Make sure you read this:


This is the time to seriously consider applying either a GVM or a GVM & BTC upgrade BEFORE registration


Once a vehicle has it VIN recorded in a state motor registry computer system you can only have the upgrade certified at a state level.


While most states allow vehicles complied in another state to be legally driven as complied in their state, if the vehicle is to ever be re-registered in another state the whole certification process needs to be started again


For a vehicle to be certified at a national level (Federal Certification) the upgrade needs to be completed before registration.


This is only available for new vehicles – hence why the Toyota Hilux KUN/GGN and Nissan Patrol GU can only attain state level certification (see Table 1 above) as they are no longer being built


Federal certification has several benefits:


  • Federal certification does not require an engineering certificate and so has a reduced overall cost
  • Federal certification carries on regardless of which state/territory the vehicle is registered in
  • Federally certified vehicles can fall in and out of registration, be sold or transferred interstate and it will indefinitely be certified with the GVM and BTC upgrades applied since new


You can imagine that this can quite significantly affect the resale value!


Definitely worth thinking about, especially considering the capital investment and depreciation of a new vehicle





Could I, or my mechanic fit the upgrade?


No. A competently trained person theoretically could install the components, but to achieve certification the upgrade must be fitted by a Production Facility approved by the Second Stage Manufacturer (SSM). 


We work to supplied quality systems documents and are regularly audited. The installation process also involves organising the required paperwork, booking time with engineer, booking time in the Production Facility workshop and completing / submitting paperwork to the relevant agencies





What about my new car warranty? 


The fitting of a GVM upgrade does not affect new car warranty.


During the design phase extensive testing and analysis procedures are conducted by an authorised Automotive Engineer Consultant to ensure original equipment components are not compromised.


The SSM is responsible to document these tests and take responsibility for the GVM upgrade compliance.


The SSM will honour any component warranty which has a failure associated with the GVM upgrade providing written proof and testing by an independent body has been submitted

Why your 4x4 needs a Long Range Fuel Tank

Read entire post: Why your 4x4 needs a Long Range Fuel Tank


Tossing up whether a big tank is a worthwhile investment? Here’s why it’s one of the best mods you can make to a 4WD.


It’s pretty simple, really. A long-range tank makes your 4X4 better. More fuel means your 4X4 can go further and longer, and long-range tanks are the best way of going about here. Here are five reasons why your 4WD needs a long-range tank.



Fitted tanks are cleaner than jerry cans



Jerry cans are cheap, but they definitely have their drawbacks. When you're decanting from drums, it’s hard to stay clean as fuel - diesel especially - attracts dust and dirt like it’s nobody’s business. It’s easier to simply fill long-range tanks at the bowser, just like you would a normal tank. Transfering fuel into and out of jerrycans can also be messy - once some spills on you, it’s impossible to get rid of the smell.

When they’re out in the elements, fuel stored in jerry cans will always be dirtier than fuel kept in proper tanks, especially when you’re out in the bush. There is just much more opportunity for water and dirt contamination. And as we all know already, a steady diet of bad fuel will lead to big and expensive engine repairs.



Retake your storage space!



You have to think about where you’re going to store your jerry cans, When you’re going long distances. Fuel inside the cab of a wagon is a no-no, and fuel storage on the roof isn’t great for a few reasons: your centre of gravity is buggered, and the tanks are difficult to access.

Long-range tanks are a true fit-and-forget modification: they take up otherwise wasted space under the body and are smartly designed to not impact on off-road ability or other mechanical parts. This also means your roof rack, ute tray or wagon storage area just got a whole lot emptier.






You can buy fuel when it’s cheap




It’s a well-known fact that fuel prices go through regular cycles of high and low prices. Service stations and fuel companies jack up the prices before weekends and holidays because they know you’re all going to be filling up the tank. And some of the more popular servos are way more expensive than others. But if you’ve got more fuel capacity under your belt, you can shift the advantage onto your side by stocking up when and where fuel is cheap, and not getting caught out when prices are high. Not many 4WD accessories help you save cash.




Aftermarket tanks are stronger



Your new tank is stronger, thanks to its construction and mounting. 2mm Aluminised steel is much, much tougher than composite and plastic; you won’t be needing a skid plate or guard to protect the tank anymore. Quality aftermarket tanks have an easily accessible drain bung, which means you don’t have to drop the tank to drop its contents. You can often choose between replacement and/or auxiliary tanks, depending on your budget and needs, which means the perfect solution for your needs is easily attainable. Here at All Four x 4 Offroad we can supply 100+ long range fuel tanks from the most popular long range fuel tanks manufacturer brands. Find one for your vehicle here!





Go farther! Go Longer!


Like, duh. More often than not, factory fuel tanks are good enough for just punting around town during the week. If you’ve got a big rural commute, or you’re planning a big trip or holiday, that small tank will quickly get on your nerves. Instead of constantly checking your gauge with range anxiety, a long-range tank gives you a much more comfortable range between re-fills.

If you’ve got a full load onboard or are towing, then your fuel range will naturally be reduced. And if you’re doing some serious off-road trips like the Simpson Desert or the mighty Canning Stock Route, then extra fuel is absolutely essential. 

And the best way to store it is in a long-range tank.

Landcruiser 70 Series Auto Conversion

Read entire post: Landcruiser 70 Series Auto Conversion



The 70 Series LandCruiser is a great 4X4, no doubt. It’s also a great vehicle for modification and improvement. One of the best things you can do is convert it to a 6-speed automatic transmission.


Automatic transmissions are a superior setup over manual, especially for off-road driving. You don’t have to button off the accelerator to change gears, which means you can maintain momentum. And a good gearbox setup with a torque converter gives you a lot more flexibility for on-road driving under load and up big hills.


You’re getting a wider spread of gears, and you’ll also pick up better comfort, smoothness, performance and economy. Compared to standard, the automatic conversion knocks almost 1,000 rpm off your tacho at highway speeds. 2,500rpm goes down to 1,550rpm, making your 70 Series quieter and more efficient.


And of course, when you’re loaded up and towing, there’s no sweat when you’re pointing uphill. Simply press the accelerator, and off-you go. Let’s have a closer looks at some of the details of the conversion.




The automatic conversion we fit is supplied by Wholesale Automatics, and it uses a new Toyota AB60 6-speed automatic gearbox featured in the Landcruiser 200 Series, which is rated for up to 900Nm of torque from the crankshaft. Tough enough for a Toyota V8, even a tuned one? You bet.



Even though the gearbox is a tough unit, a heap of upgraded parts get thrown into the package. Stuff like a billet torque converter and Nomad valve body assembly, along with great controls and cooling capabilities, take this from being a great conversion to being the ultimate conversion.


The gearbox comes with a billet CNC-machined adaptor, which mates up to the original transfer case. That means the rest of your vehicle: differentials, chassis, universal joints and driveshafts, all stay factory.










Heat is the enemy of any gearbox, so if you’re working your LandCruiser hard off-road or towing big loads, you can keep an eye on how hot things are getting with the built-in temperature gauge. This conversion also comes with a genuine Toyota cooler setup that has double the cooling capacity of a standard 200 Series LandCruiser, so your auto won’t be getting hot in a hurry.











Another great addition of this conversion is the Torque Converter Lockup. With this setup, you can choose between an automatic or manual lockup setup, which has heaps of benefits. You can go into manual lockup for economy on the highway, and also get awesome engine braking off-road. Or, leave it in auto for the extra flexibility. And for when you want to choose gears yourself, you can shift the gearbox over to tip-tronic manual gear selection.











Inside, it looks like factory. A custom centre console is used, which mounts up to the interior like it was always meant to be there. The Compu-Shift display and controls are within easy reach, and you even score a couple of 12V and USB plugs, as well as cup holders and a carpeted storage compartment. To complete the conversion, new floor carpets, complete with Dynamat noise insulation, go in to suit the new interior look. If you didn’t know about it, you wouldn’t think it was a conversion.







This conversion suits all 70-Series V8 LandCruisers: 76 Wagon, 78 Troop Carrier and 79 Single or Double-Cab Chassis

Understanding Vehicle Weights

Read entire post: Understanding Vehicle Weights



Is your 4X4 Overloaded?


Okay, first things first. Understand your weights and your terms: Tare, Kerb, GVM and GCM. One of the tricky things in understanding all of these terms is that they do vary slightly from different manufacturers. With that said, here is the simplest way:




Tare Weight: is your vehicle as it rolled off the showroom floor, full of fluids and ten litres of fuel. Sometimes it includes a 75kg driver, sometimes it doesn’t.


Kerb Weight: This is your real-world weight, as if it’s parked on the kerb and ready to drive. This includes accessories and other inclusions, plus a full tank of fuel. Want to know your kerb weight? Then get yourself to a weighbridge.


GVM (Gross Vehicle Mass): This is the most the vehicle is allowed to weigh overall, under any circumstances. This includes everything, so minus your kerb weight from your GVM to find out your payloads.


GCM (Gross Combination Mass): This is an important one if you’re towing. Aside from the GVM and trailer ATM (Aggregate Trailer Mass), GCM sits atop it all.




What’s important to note here is that in real life your maximum towing capacity and your GVM don’t add up to your GCM. In other words, you often can’t max out both at the same time. There are other considerations such as ball weight - the amount of weight your trailer or caravan is carried by the towing vehicle.



Let’s look at two examples, Toyota 150 Series Prado and 200 Series LandCruiser :




LandCruiser 200 GXL

Prado 150 GXL

Tare Weight



Kerb Weight









Braked Towing Capacity









So, is your payload always going to be enough? If you’re dawdling around town with a couple of passengers, you’ll be fine. But if you’re going to fit some common modifications and tow some decent loads, then you might run into trouble.




Think about your passengers


Now, don’t go putting everyone on the scales before stepping into the car. You might lose all of your friends. But, this point is worth thinking about. Think about travelling with five adults, which could easily account for up to 500kg of mass. Throw in a few accessories, and you could be teetering on the edge…





Think about your accessories


Everyone wants the tricked-out touring rig that has all of the bells and whistles, but don’t forget they all add kilos.


Your biggest culprits are obviously barwork: bullbars, roof racks and other bolt-on steel all add significant weight. Drawers, fridges and slides are also big ones, plus things like recovery gear, compressors and tools that live in your car full-time. Don’t forget, everything adds up.


On top of this, there are plenty of hidden weights you’ll probably overlook. If you’ve fitted tyres with a light-truck construction, that’s good news. They’re stronger and more puncture-resistant, but they will also weigh a bit more. So will fade-resistant heavy-duty aftermarket springs and shocks.


Our best advice is to take your 4X4 over a weighbridge, to really know what your 4WD weighs.



Some examples of typical weights of accessories include:







What can you do to fix the problem?


If you’ve a 4X4 that’s well set up for touring and off-roading, one of the best and easiest ways to keep your 4X4 safe and legal is to fit a GVM upgrade


This can often give you an extra 500 kilograms on your GVM, which means you can haul and tow lots more legally


They often consist of replacement springs and shocks for your 4X4. But most importantly, the upgrades are engineered to suit the increased payload, and come with a certificate of compliance





Our GVM upgrade partner - Lovells Springs - holds Compliance Plate Approvals as a Second Stage Manufacturer (SSM) of GVM upgrades for several makes of vehicle including:


  • Toyota 
  • Nissan 
  • Ford 
  • Isuzu 
  • Mazda


They are steadily expanding the range of vehicles for which they offer this upgrade.


But a comprensive vehicle list can be found in our Lovell Spring promotional page, take a look at it here

Product Review: Ironman Foam Cell Pro Suspension

Read entire post: Product Review: Ironman Foam Cell Pro Suspension


Ironman 4x4 boasts a great range of suspension options for your vehicle’s next upgrade. Generally speaking, a suspension upgrade can greatly enhance the off – road capability of your vehicle, while increasing on – road stability and weight carrying limits. To know more about general lifts, click here


To start off, Ironman 4x4 offers three variations of shock absorbers for most vehicle brands and models. On sale now, are the NitroGas, FoamCell and FoamCell Pro variations of shock absorbers. This article will specifically discuss the newest offering from Ironman 4x4, the Foam Cell Pro!


Technical Details

diagramThe suspension offers a market leading 45mm bore, coupled with a 20mm diameter shaft. The large size of the bore enables greater heat distribution which enhances the performance of the shock absorber during high temperatures and extreme conditions. The overall diameter of the shock absorber, including the inner and outer tube, comes up to around 65mm. This results in a robust looking, high performance shock absorber, incorporating its very own protection plates!



Twin Tube Design

All Ironman 4x4 suspensions are built with a twin tube design. The outer tube, which is 3mm thick, acts like a protection shield for the inner tube, which actually carries the vital components. This ensures protection against debris and rocks which may be flicked over at the shock absorbers while off the road.


Foam Cell

strongThe foam cell technology used in this shock absorber, is what sets it apart from many of its competitors. The foam cell sleeve is intricately placed in the reserve chamber of the shock absorber and has many small gas pockets in it.  When the oil is displaced from the pressure tube, it is forced into the reserve chamber, which also has the foam cell in it. Upon contact, the foam cell unit enables the oil to be distributed over the full length of the shock absorber, enabling greater heat dispersion. This results in you being able to achieve higher performance from the shock absorber, even in extreme conditions.


How much lift can I get on my vehicle?vehicle

The amount of lift that a vehicle may achieve by using these suspension kits depends on what sort of suspension set up your vehicle runs. Vehicles running a leaf spring set up, can be expected to attain a lift of 50mm, above the new vehicle height. Those vehicles running a coil spring set up, can expect to get a height raise of 40-50mm, above the new vehicle height. Vehicles running independent suspension set ups, get a smaller raise in height of 25-50mm, over the new vehicle height. This happens due to the vehicle suspension geometry restrictions that come with this set up.



  • Great handling on the road
  • Much higher level of performance off the road, even in extreme conditions!
  • Higher rate of heat dispersion
  • Perfect for long distance touring use or hard core off-road driving!


  • Paint on the outer tubes is the first to get damaged and can result in surface rust, if not taken care of!
  • The wider bore of the shock absorber may cause interferance with the movement of control arms, depending on vehicle. To find out the compatibility of your vehicle with the Foam Cell Pro shock absorber, contact us or come in store

Getting down & dirty: Driving in Mud

Read entire post: Getting down & dirty: Driving in Mud


Equipment and Techniques


Driving in mud is one of the most fun things you can do behind the steering wheel! It’s all about maintaining the required momentum to get yourself across. Read on to know more about the do’s and dont’s of Mud Driving!


TyresImage result for bf goodrich km2

The very first thing you should do, is to equip your vehicle with the correct kind of tyres. Although muddies are the way to go, you can get across just fine with All – Terrains as well, depending on the kind of mud you’re on! The deeper treads of these tyres help your vehicle in gaining much needed traction on muddy tracks. To know more about the advantages and disadvantages of these tyres click here


Underbody Protection

Image result for ironman 4x4 underbody protectionDue to the nature of driving in this terrain, it is crucial that you have good underbody protection. Since momentum is key here, there will be situations where you bottom out your vehicle on multiple occasions on unseen obstacles. Not having underbody protection may result in serious damage to your vehicle. To know more about the products available in store click here


Pick your line correctlyImage result for ironman 4x4 mud

Mud driving requires accurate picking of the line you wish to drive on. Try and pick a line with the least amount of ruts, where possible. If you’re unable to do so, walk to track ahead of you first, and then decide. Incorrect line choice may result in you getting bogged (which is pretty easy in this terrain) or worse, damage to your beloved 4x4!


Pre – Planning

So you come across a tempting looking bog hole ahead of you, and you’re almost certain you are going to give it a shot. Pre – attach one end of a snatch strap and keep the other end inside the vehicle. This way, if you get bogged, you won’t have to go digging in the mud trying to find the recovery points on your vehicle. There is also a possibility of there being an abundance of water in these situations, this way you will avoid opening the door and letting all the water in! Also make sure to try and check the depth of any mud hole with any near by sticks before entering any bog hole.


I'm Stuck, I don't know what to do!

Image result for ironman 4x4 mud Firstly, don’t panic! Try and determine whether your vehicle is bottomed out or not. If it’s not bottomed out, keep spinning the tyres at a consistent rate (don’t be Hercules with the accelerator, but keep the tyres spinning!). This will enable the tyres to self – clean their tread and hopefully get you enough traction to drive out of the situation. If this does not work, stop and get someone to pull you out! If your vehicle has already bottomed out, there is absolutely no use of spinning the tyres. Call a mate, buy him beer and ask for a snatch!



General vehicle behaviour

Given the low traction available to your vehicle in this terrain, it will behave in a very unpredictable manner. Turning your steering to the left, may not necessarily mean your vehicle will go to the left. Similar rules apply to the braking of your vehicle. Your tyres may stop moving with your brakes, but there is a high possibility of your vehicle taking much longer to actually come to a complete stop! Know your surroundings, and try and understand the kind of situation your vehicle is in. This will enable you to think ahead and be safe!


Recovery GearImage result for picking your line driving in mud ironman 4x4

Goes without saying, recovery gear is an important factor for any kind of off – road driving! Do not attempt to enter any bog holes without the correct recovery gear on board! In fact, always have at least two vehicles in your convoy. This way, if either one you gets stuck, you have another vehicle to pull you out! To see the latest deals on Ironman 4x4 recovery gear in our store click here


High Range or Low Range

Low range works best in these situations. By staying in low range, your vehicle will ensure a good amount of power is being sent to your tyres without really revving the engine too hard. Also, since your tyres will keep spinning at a consistent rate, mud will be cleaned out of them at the same time, resulting in higher traction.


Being kind to the tracks!

First things first, “take nothing but photos, leave nothing but foot prints!” (Or in our case, tyre marks!). These tracks are for everyone to enjoy, so please keep them clean! Also, try and avoid any unnecessary wheel spin in this terrain. The mud is normally very soft and you will get nowhere by doing so.  Keep up a good momentum and it should be enough to get you across. Unnecessary wheel spin will cause damage to your vehicle and to the tracks! If the tracks gets too torn up, it’ll be that much harder for other vehicles to pass through!

Stay tuned for more!
