GVM (Gross Vehicle Mass) refers to the maximum legal weight your vehicle can carry, including its own weight, passengers, cargo, and any additional accessories. Off-road vehicles like the Silverado 1500 often need GVM upgrades to handle heavier loads safely and legally especially when fitted with gear like bull bars, roof racks, canopies, or towing equipment.
At American Car Company, we offer a certified GVM upgrade that adds 130kg to your Silverado 1500’s payload capacity — without the high costs of a full suspension and brake overhaul.
Our process includes:
Vehicle compatibility check to ensure your Silverado can support the upgrade.
Certification and inspection approval for a smooth, compliant upgrade process.
Cost-effective solution at just $1295, making it one of the most affordable GVM upgrades in Australia.
