Upper control arms

The ultimate guide (2020 Update)

 

tough_dog_upper_control_arms

 

 

 

In this article where we are going to cover a few important points about upper control arms (UCA)

 

We are going to try and answer some of the most common questions you may have

 

Please bear in mind this is a general overview as suspension systems vary greatly between different model vehicles

 

 

What are suspension control arms and what do they do?

 

Upper and lower control arms are critical components on IFS vehicles that dictate the alignment of the road wheel as it moves up and down with suspension travel

 

They firmly hold the steering knuckles, axle spindles and road wheel to the vehicle while allowing the suspension to flex and maintain accurate steering geometry

 

It’s all thanks to the ball joints and rubber control arm bushings that allow this movement

 

Many controls arms (either upper or lower) have a limited range of adjustment, mainly to allow for setting camber and/or caster during wheel alignment

 

Camber is the angle of the tire with respect to the vertical axis of the car

 

Positive camber is when the top of the tire is leaning outward and the bottom of the tire is inward

 

 

Tyre-Alignment-Camber

 

 

Caster is the angle of the tire with respect to its steering axis (where it pivots when turning the steering wheel) against vertical

 

 

It is considered positive if pointing toward the front of the vehicle and negative if pointing toward the rear

 

blog

 

 

Why upgrade upper control arms?

 

 

If you have a suspension lift kit, please understand that you have just changed your 4WD suspension and steering geometry.

 


Your good-looking lift kit, other than allowing you larger tyres and more ground clearance, it has also lifted your chassis and body up and away from the mounting point of your wheels and tyres

 


Solid axle vehicles have a similar problem with the front diff rolling, but is easily corrected with some off-set bushes in the trailing arms

 

 

With IFS vehicles you need to be careful fitting a suspension lift as the original caster and camber specifications are pushed outside the acceptable limit

 


A lack of enough adjustment combined with typically short control arms causes your vehicle to lose camber/caster

 


This can cause your steering to become vague (tracking) with an out of control feeling

 


These issues can also greatly accelerate tyre wear costing you more money in the short term


 
To make things worse, fitting larger tyres can hit suspension components and even make contact with the chassis which is a problem that nobody needs

 

 

From the factory, most IFS 4WD's only come with a small amount of adjustment however, this is reduced when you add a suspension lift to your vehicle

 

 


This means when you do a wheel alignment, there will not be any adjustment available to set your vehicle’s camber or caster correctly

 


And please know that your vehicle’s instruction manual wheel alignment specs page does not take into consideration raised suspension or tyre size

 

Another serious issue found when lifting a vehicle with IFS is running out of movement in the ball joints

 


This is called ball joint binding and is caused by changing the suspension geometry to a point where the ball joint simply cannot move to a larger angle

 


The ball joint itself comes into contact with its own housing effectively reaching its maximum angle

 


While the ball joints may look okay parked on flat ground, when under conditions involving significant articulation (lots of suspension travel/extreme offroad) this can cause the ball joint to separate (pop out of socket) with the road wheel and steering knuckle coming loose from the control arm

 


Far from ideal!

 

 

So, what to do?

 


 
Simple:

 

 


Install modified upper control arms to your IFS 4WD


 

 

Luckily here in Australia, we have a choice of quality aftermarket upper control arms from well-known brands that can resolve all these issues

 


They have been redesigned to provide a better geometry for lifted vehicles, allowing the use of the standard adjustment for setting wheel alignment

 


They will effectively help to get the maximum performance and lifespan from your suspension, steering components and tyres

 


The positioning of the ball joint allows it to sit in a more neutral position providing full range of travel as per OE specs, effectively eliminating the binding issue

 

 

 


Tough Dog and Blackhawk by Roadsafe are among those


 

 

Here is a brief introduction of both:

 

 

Tough Dog upper control arms

 

 

UpperControlArm

 

Tough Dog upper controls arms features are:

  • Fixed position arm with increased caster (built in)
  • 1020 grade forged ball joint housing and end-rings (bush end)
  • Heavy duty, greaseable ball joints of OE size for easy replacement
  • Grease-free synthetic elastomer bushings
  • Free-pivoting bushings remove the chance of binding
  • increased clearance to strut/coil spring at full droop
  • increase strength exceeding OE versions

 

 

 

 

 

Blackhawk upper control arms (by Roadsafe)

 

 

 

326823_uca3841h_3_1024x467_full

 

 

 

Roadsafe upper control arms:

  • Fixed arm with increased caster (built in)
  • OE style/size rubber bushings
  • OE style/size ball joints.
  • Increased strength over OE

 

 

A lot goes into the design and manufacturing of an upper control arm kit

 

Thousands of dollars are spent in computer modelling, prototypes and testing before going to the market

 

Here in Australia they need to meet or exceed OEM specifications with the appropriate paperwork and engineering reports to receive ADR compliance (Australian Design Rule)

 

Although designed and manufactured to be ADR compliant this can be somewhat confusing as there is no Australian Design Rule for specific products like upper control arms

 

Roadsafe have ensured their control arms mount to standard fitment positions, have not moved or changed any of the mounting points and used OE specifications for bushings at the chassis

 

More detailed information is available upon request

 

 

 

Not all upper control arms are created equal

 

 

Different users (and uses) - different needs

 

Some aftermarket control arms are fully adjustable in both camber and caster, others have spherical joints at both ends

 

Tough Dog and Blackhawk UCA’s use a fixed position ball joint with heavy duty, OE specifications for the ball joint itself

 

Both brands specifically chose a fixed ball joint for off-road applications as the ball joint receives a large amount of bump / shock loads

 

Over time this could knock an adjustable ball joint out of position

 

These brands provide standard features such: 

  • 3 or more degrees of fixed caster correction which is the perfect amount of correction required for lifts ranging from 30-70mm
  • A fixed amount of caster offers the ability to use the factory adjustment to fine-tune the caster required for the vehicle's lift
  • Camber adjustment to meet OE specs
  • Maintain OE specification ball joint & bushings – you can use genuine replacement parts or aftermarket OE in case you need to replace a ball joint or bushing (OE spec bushing for Blackhawk only)
  • Positions for factory mounting of brake lines
  • Increased strength compared to the OE design 
  • Heavy-duty long-life ball joints

FJ40 FJ45 BJ40 BJ42 HJ45 HJ47 may sound like digits of a Medicare Card or Tax File Number but not for the passionate four-wheel driver enthusiast. He/she knows that those are the models of one of the most iconic 4wd of all time: the Toyota Land Cruiser 40 Series.

 

In this article, we’re going to cover off a few simple 40 series Landcruiser maintenance tips you can complete at home with a basic set of skills and tools. 

 

But before jumping in, it's fair saying that 4wd owners' friendly rivalry between the different brands of 4wds is one of the joys of being a passionate owner of an off-road machine.

 

There are a few 4wds that unite owners together: the Willys Jeep, a G60 Patrol or a Land Rover Series 1 short wheelbase. Such vehicles that we tend to agree are “just cool”.

 

There’s another 4wd that this article is going to cover off that arguably has no haters and that is the Mighty 40 series Landcruiser Troopy.

 

The 40 series Landcruiser Shorty has explored every corner of Australia numerous times and made itself famous for its exploits crossing remote deserts, floating across the Jardine River, to competing in the Tuff Truck Challenge.

 

Like all things man-made it has a couple of areas that need to be kept an eye on so let's explore how you can do them at home.

 

 

Let's dive in:

 

 

Check #1: Steering system

  • The 40 series Landcruiser power steering system has the bell crank Steering Idler Box out front on the chassis rail which is well known to wear and will cause sloppy steering response. It’s worth checking all Tie Rod Ends and Steering Box along with the steering system for play in any of the components. These are usually easy to adjust or change out although you may need to get a wheel alignment after this work.

 

 

 

Check #2: Wheel bearings

  • Jack up the front wheels and use safety stands, then hold the tyre top and bottom, push and pull the tyre to feel for play in the wheel bearings. Rotate the wheel feeling and listening for ‘rumbling’ that will indicate failing bearings. A slight rubbing sound could be the brakes and would be seen as normal. The rear bearings are a little harder to feel because the axle is connected to the wheel hub on full floating rear diffs from 09/1975 on. In an ideal world, you should remove the axle to check the rear bearings.

 

 

 

Check #3: Oil leaking

  • Look for oil leaking onto the inside of the tyre, this would be from the wiper seals on the front steering knuckle. This would often require a swivel hub rebuild as it is you will need to replace the inner axle seal fitted to rectify.

 

 

 

Check #4: Inlet manifold

  • On the petrol 2F motor, the inlet manifold is known to warp which will cause vacuum leaks that cause rough idle, a lean mixture and poor running

 

 

 

Check #5: Ignition components


 

 

Check #6: Ignition base timing

  • Check the ignition base timing and vacuum advance with a timing light.

 

 

 

Check #7: Diesel injection pump

  • The 2H Diesel injection pump on an HJ47 is vacuum operated and has a tendency for the leather diaphragm to fail to cause fast idle issues. This can be easily fixed by All Fourx4 but does need the expertise to change. If your oil pressure gauge reads high it indicates the common issue of a sticking oil relief valve. It’s easily fixed with an updated valve. 

 

 

 

Check #8: Air filter

  • Clean the air filter with compressed air by blowing from the inside out.

 

 

 

Check #9: Fluid levels

  • Check all fluid levels and condition by making sure the differential, gearbox and transfer case oils are not water contaminated. If the oil looks grey there’s water present and the component needs to be drained and flushed. You could consider fitting an extended diff breather system to stop water ingress in the future.

 

 

 

Check #10: Brake and clutch fluids

  • Consider flushing the brake and clutch fluid depending on when it was last done.

 

 

 

Check #11: Rubber hoses and belts

  • Inspect all rubber hoses and belts for cracks, leaks and signs of perishing, change as necessary.

 

 

 

Check #12: Fan Belt tension

  • Check Fan Belt tension. The correct tension is about 15mm of play in the longest run of the belt.

 

 

 

Check #13: Handbrake system

  • Check and adjust the handbrake system, this is normally located at the back of the Transfer Case.

 

 

 

Check #14: Inspect the radiator

  • Visually inspect the radiator for signs of coolant leaks around the core and tank joints.

 

 

 

Check #15: Spring shackle bushes

  • Using a pry bar, lever all spring shackle bushes inspecting for wear and play. 

 

 

 

Check #16: Inspect the springs

  • Inspect the springs for any broken leaves.

 

 

 

Check #17: U-bolt tension

  • Check U-bolt tension.

 

 

 

Check #18: Shock absorbers


 

 

 

Check #19: Grease nipples

  • Grease all grease nipples on the steering and drive shafts.

 

 

 

Check #20: Universal joints


 

 

 

Check #21: Differential drive flanges

  • By pushing up and down feel the differential drive flanges for play and signs of leaking from the pinion seal.

 

 

 

Check #22: Body mounts

  • Visually look at the body mounts to see if they are compressed or cracked, If they are they’re relatively easy to replace and will ensure the body stays connected to the chassis which is a good thing.

 

 

 

Check #23: Tyre pressures

  • Check all the tyre pressures and their condition. Look for deep cuts and irregular wear patterns. Consider doing a tyre rotation.

 

 

If you end-up needing new 40 series parts and start typing on Google things like "40 series Landcruiser Parts Australia" etc, you may not always find what you really need.

 

40 series Landcruiser body parts, Landcruiser 40 series chassis parts, or 40 series Landcruiser roof console, for example, are not always easy to come by, however, can be found in specialist 4wd shops such as the one you are reading right now.

 

All Four x 4 Spares stocks a wide range of 40 series Landcruiser parts for sale in this website and they provide a massive help whether you are doing a 40 series restoration or just a service.

 

If unsure give them a call on (02) 4041 4041 for any of the service items you may require such as 40 series power steering kit, 40 series air conditioning parts or if you need quality second hand 40 series doors, you may find them in their 40 series Landcruiser wreckers department.

How to look after your 4WD's Automatic Transmission

Read entire post: How to look after your 4WD's Automatic Transmission

 

auto_conversion_orto1

 

 

Today we are going to talk about 4WD AUTOMATIC TRANSMISSIONS and how you can keep them in perfect shape without breaking the bank.


 

Automatic transmissions are a weird and wonderful design, as some would say foot goes down, magic happens, and power comes out. (If you like geeky stuff and want to learn more of how an Automatic Transmission works in engineering terms then watch this video)

 

How an Automatic Transmission works:

 

Auto transmissions are super easy to operate so that you can hold the wheel with one hand and eat a burger with the other, but, unfortunately, the driving force of our vehicles is not quite so simple and just the same as our engines, they require regular maintenance and pre-emptive modifications to aid the overall performance and longevity of our transmissions.

 

This, of course, starts with regular servicing of the oil and filtration system to give your transmission the best bet to keep performing at its best potential.

 

 

What is the biggest killer of an automatic transmission?

Good question, the simple answer is heating,

an overheating transmission is one of the leading causes of costly failures to our automatic transmissions.

 

OVERHEATING_TRANSMISSION

 

 

So, what causes this excessive heat?

Again, brilliant question! You’re good at this!

Number one measure of maintaining your transmission, and ensuring your internal oil temperatures are kept cool and manageable is a heavy-duty auxiliary transmission cooler

Mitsubishi-Triton-MQ-MN-Cooler-and-Bracket-800-x-800-1-400x400

 

yes, most vehicle manufacturers do have automatic transmission coolers fitted, however, these systems are tested under moderate conditions and not pushed to the true tough conditions our four-wheel drives are used for, be it fully loaded tough touring, towing the boat or caravan every weekend or hardcore four-wheel driving!

 

These are the areas where your standard transmission cooler will begin to build up excessive heat, causing hard-shifting and even worse, possible failure due to burnt/prematurely worn oil.

 

 

So how do I avoid this excessive heat, you ask?

I thought you’d never ask! Time for a home run.

 

As previously mentioned a heavy-duty front mount auxiliary transmission cooler is going to make an immediate difference to the performance and longevity of your transmission.

 


All Four x 4 Spares have a wide range of automatic transmission coolers specific to suit many makes and models, our coolers come with an especially Australian designed and manufactured mount which allows optimal airflow directly from the grille of your vehicle, ensuring the most efficient cooling possible!

Each kit has a top-quality, tried, tested and proven PWR cooler and 4mm thick E-coated mounting bracket, as well as high-quality hoses and fittings to suit, meaning you get the maximum confidence in your transmission cooling system. Give us a call on 02 4041 4041 to order one for your vehicle.


 

Although we touched on some key points above that will cause heat to rise to a damaging level in your transmission it is important to remember that on a hot day in even a lightly-loaded vehicle something as minor as a slight uphill rise can cause a major peak in transmission temperature leaving you stuck roadside, with a possibly failed transmission.

 

Much like having a winch fitted to your vehicle, an automatic transmission cooler is cheap insurance, not only making for a more comfortable drive from your transmission but potentially saving you thousands in costly repairs due to a failed transmission!

 

 

My Automatic Transmission is dead

 

If you are in a situation where your automatic transmission has completely failed, well then you won’t have any other options other than visiting an automatic transmission repairs workshop

 

Not wanting to blow our horns but our team of automatic transmission mechanics are specialists in transmission repairs, overhauls and auto transmission rebuilds. 

 

They’ll repair your automatic transmission with the highest level of speed and efficiency possible. If you are after some of the best automatic transmission mechanics in Newcastle and Hunter region only two hours drive from Sydney, then look no further and give them a call on 02 4041 4003

What about 4WD Manual Transmissions?

 

Does your 4WD have a manual transmission? All these automatic transmission talks may make you wonder what would be like off-road driving with an automatic transmission. 

 

Do you know that you can change your manual transmission to automatic? And let’s say you own a 70 Series Landcruiser and you want to make her quieter at highway speeds by dropping the rpm’s off your tacho and provide an overall improvement in comfort, performance and fuel economy.

If you’re one of those fortunate people who own a Toyota Landcruiser 80 series (any models such FJ80 FZJ80 HZJ80 HDJ80 etc), there is a slight possibility it needs a little bit of COVID-19 love from you. (If you’ll land here from the future: this post was written in May 2020 during the Coronavirus lockdown)

 

In this article, we’re going to cover off a few simple tasks you can complete at home with a basic set of skills and tools. 

 

Your 80 Series Land Cruiser service and maintenance will vary depending on how you have set it up and how you use it. The service requirements will vary slightly so with this in mind lets touch on some of the items you can look at for your vehicle.


 

Starting at the front end:

 

Task #1: Check the steering system

 

Check all bolts on the steering linkages and associated components. Check the steering system for play and adjust as required.


 

 

Task #2: Inspect the lower kingpin studs

 

The lower kingpin studs are known to come loose and should be checked with a torque wrench. (71Ft-Lbs/96NM) If they look as though they have been loose for some time it would be advisable to strip the knuckle down and investigate for any damage. Look for burrs and wear around the holes, studs and where the steering arm joins the knuckle. Check our Swivel Stud Kits in stock

 

swivelstud

 

 

 

Task #3: Inspect the steering box and upper panhard chassis mount

 

for fatigue cracks. These can be repaired with one of the many welds in repair kits available.


 

 

 

Task #4: Inspect the power steering hoses, pump and reservoir for leaks and weeps

 

The power steering reservoirs are renowned for weeping around the top crimp. 

 

powersteer_res

 

power_steer_lines_

 

Task #5: Inspect all tyre pressures

 

and look for feathering, scalloping, cuts and uneven wear patterns and tread wear indicators. 


 

 

 

Task #6: Inspect the wheel bearings

 

Jack up each wheel and by holding the top and bottom of the tyre feel for any play in the wheel bearings. Rotate the wheels feeling and listening for abnormalities like rumbling or scraping sounds. Be aware that the brake pads may make a slight rubbing noise which is ok. The rear bearings are a little harder to feel because the axle is connected to the wheel hub. In an ideal world, you should remove the axle to check the rear bearings. Our range of: Wheel Bearing Hub Kits


 

 

Task #7: More checks around the wheels

 

While you are at each wheel look for oil leaks around the knuckles and hubs. I also inspect the shock absorber and sway bar bushes at this time.

 

swaybar_front

 

 

 

Task #8: Check the rear control arm bushes

 

Using a pry bar check all the front and rear control arm bushes for cracks and failures.

 

control_arm_bushes

 

 

Task #9: Check the rear axle drive hub studs and nuts

 

for signs of flogging, fretting and oil leaks. Check our 80 Series Rear Axle Hub Studs

 

axle_studs

 

 

Task #10: Check for worn seals

 

If you decide to repack the wheel bearings it’s worth considering the use of the Terrain Tamer Heavy Duty bearing kit. This comes with a cassette seal which resolves issues with worn seal surfaces.


 

 

 

Task #11: Check all fluid levels 

 

and condition making sure the differential, gearbox and transfer case oils are not water contaminated. If the oil looks grey there’s water present and the component needs to be drained and flushed.


 

 

 

Task #12: Check the air filter

 

for dust and blow it out from the inside with compressed air. Clean out the dust trap under the air filter box.

 

dust_trap_

 

 

Task #13: Check the condition and tension of all fan belts 

 

There should be no signs of cracks or fraying. The correct tension is about 15mm of play in the longest run of the belt.

Check our 80 Series Fan Belt Kits

drive_belt

 

 

Task #14: Check all hoses 

 

for leaks or damage and coolant hoses shouldn’t feel crunchy when you squeeze them.


 

 

 

Task #15: Grease the nipples..

(no, we don't mean to put grease on your partner’s nipples)

You’ll find 3 grease nipples on both front and rear driveshaft, grease these with a quality general purpose grease.


 

 

 

Task #16: Check the handbrake operation 

 

There should be 7 clicks when you pull on the hand brake lever and the car should hold on a slight slope.

What are parabolic leaf springs?

 

Terrain_Tamer_Parabolic_springs_suspensions_2

 

Terrain Tamer has recently introduced new parabolic leaf springs for the popular Toyota LandCruiser 70 Series and Toyota Hilux and we thought to put together different resources from Terrain Tamer itself as well as independent reviewers in order to describe what they are and how they work.

Allan_Gray_Terrain_Tamer

 

 

Allan Gray from Terrain Tamer wrote a great article about Parabolic Springs on the Automotive Technician Magazine.

 

 

 

Allan Gray's definition of parabolics is: a suspension system used many years ago when vehicles were produced using one, two or three tapered leaves instead of multipacks.

 

The idea was successful but appeared to go out of fashion when coil springs started being fitted to the form of family cars and light trucks. However, while parabolic tended to disappear from the light truck scene, they continued to be chosen for heavy-duty track applications.

 

Now Terrain Tamer has released a new design in parabolic leaf springs, bringing the technology back to the Toyota Landcruiser 70 Series.

 

The new springs are thicker in the centre and taper towards the ends in a true parabolic form, and each leaf is designed to act as a spring in itself. The standard spring is supplied with three leaves - two main leaves that operate when unloaded and a lower leaf that contacts the upper leaves through a pressure pad when a full load is being carried. It's proof of what happens when modern technology is applied to a well-proven idea.

 

Parabolics are now fitted standard to many vehicles, both light and heavy-duty, for a smoother quieter ride, lower unsprung weight and greater flexibility. During Terrain Tamer testing, they placed cameras on the undercarriage area to check articulation, chassis clearance and brake and acceleration characteristics.

 

It soon became evident that owing to the increased flexibility of the parabolics, any excessive load on the driveline resulted in the differential housing deflecting with the springs, reducing the shock loading on the crown wheel and pinion.

 

This situation is particularly advantageous in four-wheel driving situations, where rapid forward and reverse gear selection is often used to extricate a vehicle from an embarrassing mud-hole incident. As with all Terrain Tamer products, these springs have been tested in the rugged situation of the Australian outback.

 

Greater flexibility, quieter operation, up to 500Kg capacity and improved driver comfort, it's a win-win situation and once you fit them, you will wonder how you ever did without them.

1KD-FTV Injectors, tips that may help save your engine

Read entire post: 1KD-FTV Injectors, tips that may help save your engine

 

What's in this blog post has been experienced first hand quite a few times from our guys in the workshop so we thought to do our bit to inform people to act promptly and save their vehicles.  

 

Prado & Hilux 1kd-ftv engine (up to 2007) d4d common rail diesel owners: this one is for you. Please pay close attention to this read.

 

toyota_1kdftv_engine_ser1_04

 

 

This is about the infamous injector copper washers (or seals). Unfortunately and eventually they will likely all leak.

 

 

1KD-FTV Injectors, tips that may help save your engine

 

 

During compression, the heat eventually melts out the rubber o-ring which is up a little above the copper washer. And above the o-ring, there is an oil channel. The oil that comes down from the injector port gets carbonised into tiny pieces that will end up floating in the oil system and then in the oil sump.

 

Then when the engine is looking for oil, it will find and suck these tiny particles. Result? Your oil pickup will eventually get blocked.

 

 

Injector_Combustion_leak_significant_carbon_desposits

 

 

When that happens, you will get lubrication problems and oil starvation and the very first victim will be the bottom end bearings. Your vehicle will start running crap, the oil light will come on and voila, if you are in the middle of the road, you'll need to be towed away. Plus say goodbye to those Bali holidays savings because you'll be up for a new engine and turbo $$$$

 

This scenario will affect all those 2006 & 2007 vehicles that are still running around with the older generation of copper washers. From 2008, Toyota introduced and fitted revised coated washers.

 

If your vehicle is in that year bracket, we can only recommend finding an experienced diesel workshop with experience on 1kd-ftv engines. Some may try DYI but up to your knowledge and confidence to get it right.

 

Have the injectors and washers checked and replace them only with genuine Toyota or at least with a high-quality aftermarket brand such as this. There are a number of aftermarket brands offering brass washers but that caused controversy among experts due to the nature of brass, a hard material that can't flex and stay sealed.

 

The same goes with o-rings, any other seals, gaskets, fuel pipes, don't use cheap parts. If your injectors and washers are still the original from 2006, replace them asap. Newly revised copper washers should last every 120.000Km. And don't even think of reusing older washers.

 

Many common rail diesel owners are aware of this and are on top of it, but many more don't realise the amount of trouble they can get into...so do your vehicle a favour and get those injectors checked!

The dampers operate unlike any other product on the market and feature world leading technology that provides the owner with off-road capability not available anywhere else. Drivetech 4x4 Supashock Dampers are designed with automotive, mining and defence expertise, manufactured from aerospace and defence grade materials and assembled and tested in a world class facility, all under one roof in Adelaide SA. It is truly a unique product.
 
 
Supashock_Performance
 
 
Australian designed, tested, manufactured and assembled
 
Drivetech 4x4 Supashock dampers are designed, tested, manufactured and assembled at Supashock’s world class manufacturing and test facility in Adelaide, South Australia by a highly experienced engineering team. With a focus on delivering optimal ride quality and performance, the dampers were developed using the best of proven Supashock technologies from racing, mining, military and performance vehicles.
 
The Drivetech 4x4 Supashock suspension lift kits combine the expertise and experience of Supashock and Drivetech 4x4 in the development and production of vehicle specific kits. 
 
 
 
Drivetech 4x4 Supashock Inverted Strut Technology
 
Drivetech 4x4 Supashock’s Inverted Strut Technology, developed in motorsport and mining applications, provides each damper with superior strength and durability. Its strong, durable and rigid construction means that the Drivetech 4x4 Supashock is able to generate a huge amount of force without buckling or bending.
 
The 64mm diameter main shaft is constructed using high quality aerospace grade alloy. The main shaft and outer casing provide incredible resistance to bending and buckling when carrying heavy loads and during large impacts. The system also incorporates a redundant sealing system which acts as a second seal preventing the main seal from being damaged by rocks, mud, water or other corruptive ingress material. It also eliminates hydraulic fluid loss and maximising service life.
 
 
Drivetech_4x4_Supashock_Cutaway
 
 
Drivetech 4x4 Supashock High Displacement Pneumatic Bump and Ride Control
 
Supashock’s High Displacement Pneumatic Bump and Ride Control system provides additional load bearing capacity, reduces harshness and acts as a pneumatic bump stop. The system, developed for mining vehicles to minimise operator injuries, uses an innovative design to build pneumatic pressure where is it needed and soften the harshness generated by road inputs.
 
During high wheel articulation events, the system also acts as a pneumatic bump stop, providing a cushioning effect on hard landings and regulating the stress transferred into other components on the chassis, extending their service life.
 
 
 
Drivetech 4x4 Supashock Input Response Technology
 
The most significant performance characteristic of the damper is Drivetech 4x4 Supashock’s Input Response technology. This technology gives each damper ultra-fast reaction times as soon as the shaft starts to move. As the wheel goes over a bump, the damper responds instantly, controlling the motion. Similarly, when turning, the reaction of the tyre on the road surface is transmitted to the steering wheel with minimal lag, providing extremely precise handling.
 
The overall benefit of this technology is that the valving on a Drivetech 4x4 Supashock damper can be a lot softer than other products to provide a comparable level of vehicle control, because the damper is able to control wheel and chassis motion faster. Softer valving reduces harshness and stress on the chassis and the internal components of the damper, increasing their service life.

Tuned Damping and Operating Window
 
Each Drivetech 4x4 Supashock suspension lift kit is tuned specifically to the application and the variety of road conditions it will be exposed to. The dampers have been designed and tuned so that they do not require external adjustment, providing a wide operating window and unrivalled performance on the market.
 
The key component is Supashock’s proprietary piston and valve assembly design. Developed in-house and currently used in top-level circuit racing, off-road racing and mining, these components provide linear oil flow and efficient flow control to maintain consistent damper performance in all conditions. The damper can cope with large and rapid shaft displacements while still being able to soak up smaller bumps without causing harshness. The high response of the damper transmits steering inputs to the tyre instantly and ensures the tyre has maximum contact with the road surface for traction, giving the driver confidence, razor-sharp handling and an extremely stable vehicle on sealed or unsealed roads.
 
Most high-performance products on the market utilise external adjusters to change the damping forces. This is needed because they have a narrow operating window. This is due primarily to the adjustment orifices generating additional flow restrictions and turbulence in the oil. This promotes cavitation (aeration) and thermal degradation (damper fade). The result is a vehicle that has inconsistent handling performance in varying conditions and has poor control of the wheels, causing them to lose contact with the ground more frequently. 
 
 
 
Supashock’s Patented Shell Reservoir System
 
Each damper features Supashock’s patented Shell Reservoir system which provides the performance benefits of a monotube damper packaged into the same space as twin tube damper, without the need for an external canister.
 
The Shell Reservoir system has a floating piston that separates the pressurised gas from the oil and allows for a larger oil volume than most remote canister dampers on the market, making it extremely thermally efficient. There is also no need for external brackets to be mounted for canisters or additional hardware.     
 
 
 
High-Performance Bushes
 
The bushes used in the dampers are manufactured using a specially designed material compound developed in Australia for mining vehicles. The material has extremely high resistance to cracking and hardening and can carry extremely large loads. The stiffness characteristics of the material have been tuned to maximise service life and minimise harshness. 
 
 
 
Materials
 
The dampers are manufactured from aerospace alloys and the highest quality hard chrome rods. Surface coating technology developed in mining and defence provides extremely hard and durable surfaces on every component, giving them the ultimate resistance to sand, mud, rocks and fluids. 
 
 
 
Adjustable Spring Pre-load & Stress Relieving Seat
 
All coil-over-type front struts have adjustable spring seats for ride height adjustment. The adjustment system features a stress-relieving seat that allows for easy adjustment and eliminates torsional spring stress during damper compression, providing consistent performance and extending the life of the spring.
