GVM upgrades & suspension systems

GVM upgrades & suspension systems

Increase the load-carrying capabilities of your 4WD with a GVM upgrade.
Owners of four-wheel drives regularly need to load up their vehicles, whether for work or play, and this can quickly exceed the vehicle's legal Gross Vehicle Mass. When a vehicle exceeds its Original Equipment GVM, the safety of the vehicle, its occupants and others on the road is compromised, which is why overloading a 4WD is both dangerous and illegal.

With a GVM upgrade from BTA 4WD Centre, you can carry more with confidence and ease in any situation. A GVM upgrade not only improves the performance potential of a 4WD but also satisfies a variety of legal requirements for potentially overloaded vehicles, including road legality, Occupational Health & Safety, vehicle insurance and much more.

For those who do not require the weight increase, a suspension kit will improve handling and make your vehicle more comfortable and safer while maintaining the manufacturer's standard GVM.
