GVM UPGRADES
Complete GVM Upgrade Kits
Carry more. Tow more. Legally.
A Tough Dog GVM (Gross Vehicle Mass) upgrade is a fully engineered, certified suspension package that legally raises your vehicle's maximum loaded weight. Each kit is matched to a specific vehicle and load target — pick your truck below to see the available configurations.
What is a GVM upgrade?
GVM is the maximum your vehicle can legally weigh fully loaded — vehicle, passengers, fuel, accessories and payload. A certified GVM upgrade replaces your springs and shocks with a heavier-rated, engineer-approved system so you can carry bull bars, drawers, water, tools and a full tray or canopy without overloading. Each kit is supplied with the compliance documentation required for your state.
