Gross Vehicle Mass Upgrades – GVM

Gross Vehicle Mass Upgrades – GVM

When a vehicle is fully loaded for travel or equipped for work trade, it may be overloaded beyond its GVM and Payload capacity. Items such as tools, tool boxes, cargo, bull bars, winches, towbars, fuel, accessories, passengers, recovery gear all combine to add weight to a vehicle and decrease the available payload. It is also important to note that the weight of any tray or service body is also considered to be part of the ‘kerb weight’ and therefore further reducing the available payload.

Every road vehicle has an official legally allocated Gross Vehicle Mass rating (GVM) and Payload Capacity (how much weight a vehicle can carry in both passengers and cargo). The GVM rating is the maximum allowable weight figure (in kg’s) as specified by the manufacturer when fully loaded.

United Auto Engineering offer GVM upgrade solutions for your vehicle. If already fitted with upgraded springs and shocks, United Auto Engineering, being a Light Vehicle Engineering Signatory (LVES), can asses your vehicle and endorse an upgraded GVM rating for registration in South Australia. Alternatively, United Auto Engineering can supply, fit and certify your choice of upgraded suspension to obtain an upgraded GVM.

So if you’re unsure about the GVM of your vehicle or if you think that you are running your vehicle over the legal weight limit, then contact United Auto Engineering and we can then advise you of what options are available for your vehicle.
