Tough Dog Upper Control Arms
Tough Dog Upper Control Arms suitable for Hilux, Ranger, 200 Series & Prado
Tough Dog Upper Control Arms are built tough
When an IFS vehicle is fitted with a suspension lift, the original caster and camber specifications are pushed outside the acceptable limit. The vehicle loses caster which makes the steering vague, and positive camber is introduced, which contributes to uneven and accelerated tyre wear.
Tough Dog Upper Control Arms can help get the maximum performance and lifespan from your suspension and steering components.
The end housings are forged from 1020 grade steel, as is the ball joint housing, which has been specifically crafted with a slimline design to maximise clearance. The bushings are heavy-duty, high flex style design requiring no lubrication, for maximum life span in rough terrain. The ball joint is constructed of high strength Chromoly steel. For ease of servicing, all Tough Dog UCAs are designed to accept original equipment ball joint parts as spares should you ever need to.

Do you need a Tough Dog GVM Upgrade?
Your vehicle may get "overweight"
If you’re carrying heavy loads, towing, or heading off-road, your vehicle’s standard Gross Vehicle Mass (GVM) may not be enough. Exceeding factory limits can lead to unsafe handling, reduced braking performance, premature suspension wear, and even insurance or legal issues. A Tough Dog GVM Upgrade increases your vehicle’s legal load capacity, giving you improved stability, safer braking, and compliance with regulations. Whether you’re touring, working, or towing, a certified Tough Dog GVM Upgrade helps protect your vehicle, keeps you road-legal, and ensures you can confidently carry what you need.
Carry More – Safely & Legally with a Tough Dog GVM Upgrade
A Tough Dog GVM Upgrade allows you to increase your vehicle’s legal payload capacity while staying fully compliant with Australian Design Rules (ADRs). As a recognised Second Stage Manufacturer (SSM), Tough Dog Suspension develops and federally certifies suspension components to raise your Gross Vehicle Mass safely and legally. Each complete GVM upgrade kit is rigorously tested to ensure your 4WD maintains roadworthiness, safety, and performance — even under heavy load.
Safety and Performance by Design
Every federally approved Tough Dog GVM Upgrade undergoes extensive testing to ensure your vehicle handles as well as, or better than, when it left the factory. This includes:
- Finite Element Analysis (FEA): Confirms axle load-carrying capacity.
- Brake Testing: Laden, unladen, and partial system failure tests to comply with ADR35/00.
- ESC Testing (where required): Ensures electronic stability control continues to perform to original or improved standards.
With a Tough Dog GVM Upgrade, your 4WD will continue to stop, steer, and handle safely — even with the increased load.
Understanding GVM and Compliance
The Gross Vehicle Mass (GVM) is the maximum legal weight your vehicle can carry when fully loaded. Tough Dog GVM Upgrade kits allow your 4WD — whether it’s a LandCruiser, Hilux, Ranger, Patrol, D-MAX, or other popular models — to be certified for a higher GVM without breaching ADRs or state laws.
- Pre-Registration (Federal Approval): If your vehicle hasn’t yet been registered, the upgrade can be certified at the federal level. The Tough Dog kit includes an additional compliance plate fitted to the vehicle.
- Post-Registration (State Approval): For vehicles already on the road, data from federal testing is combined with a state-based inspection by an authorised engineer to certify the upgrade.
With Tough Dog’s proven suspension technology and full federal accreditation, you can tow, carry, and tour with confidence, knowing your GVM upgrade is both legal and safe.
