Why Upgrade?

Carry More. Do More.

American trucks are built tough — but when they arrive in Australia, factory GVM ratings often don't match what you actually want to carry. Accessories, tray bodies, canopies, fuel tanks, and camping gear add up fast.

Exceeding your GVM is not just an insurance risk — it's a legal liability. Our certified GVM upgrade packages give you a higher legal payload, so you can load your truck properly without compromise.

Common Questions

FAQ

Everything you need to know about GVM upgrades, eligibility, and compliance.

GVM (Gross Vehicle Mass) is the maximum legal weight your vehicle can be — including the vehicle itself, fuel, passengers, and all cargo. Many American trucks, when fitted with accessories, canopies, tray bodies, or heavy gear, exceed their factory-rated GVM. This is illegal and can void your insurance. A GVM upgrade is a certified engineering modification that legally increases this rating, so you can carry what you need without risk.

Our GVM upgrades are performed by certified automotive engineers and comply with Australian law. Under the Australian Consumer Law and Competition and Consumer Act, manufacturers cannot simply void a warranty because you've had a third-party modification. They would need to prove the modification directly caused any fault. We recommend discussing this with your manufacturer and we can provide documentation to support your position if needed.

We have packages available for: Chevrolet Silverado 1500 (2014–2026), Ford F-150 (2015–2026), RAM 1500 DT (2019–2026), and Toyota Tundra (2007–2024). Package availability may vary by year and variant — contact us or visit an authorised dealer to confirm your specific vehicle's eligibility.

Most GVM upgrade installations are completed within a single business day. Your authorised dealer will confirm the timeframe when you book. In some cases involving additional components or modifications, an overnight stay may be required — your dealer will advise upfront.

Requirements vary by state. In most cases, your updated compliance plate is sufficient — no separate notification or inspection is required. Your authorised installer will advise you on any state-specific requirements and provide all necessary documentation to support any notifications that may be needed in your jurisdiction.

Yes — and that's exactly what our lift-height package options are designed for. Our 2" and 4" lift packages combine a certified GVM upgrade with a matched suspension lift kit. Everything is engineered to work together, keeping your vehicle compliant and your ride quality intact. It's the most efficient way to get more clearance and more legal payload in a single install.
