GVM Upgrades
Local and Domestic GVM Upgrades
A GVM (Gross Vehicle Mass) upgrade increases the legal carrying capacity of a vehicle by installing an approved suspension kit, allowing for more accessories like bull bars and roof racks. However, it has limitations, especially when towing. The upgrade involves replacing factory suspension components, sometimes requiring additional brake or tyre upgrades to meet safety standards.
If your vehicle consistently approaches or exceeds its factory GVM, an upgrade may be necessary. Overloading a vehicle can make it unroadworthy and void insurance. Pre-registration upgrades are cheaper, but post-registration upgrades require certification from an engineer. GVM upgrades can affect ride quality, especially when unladen, and all kit components must be used without modification.
While useful for heavy-duty use, GVM upgrades aren't suitable for every vehicle, and careful assessment of your vehicle’s load and needs is crucial before upgrading.
EC Offroad offers a range of Pre Registration and Post Registration GVM Upgrades for a large number of vehicles. Check out the vehicles below and what's involved in upgrading the weights to suit your needs
