WHAT IS A GVM UPGRADE?
A GVM upgrade most commonly consists of replacing the original suspension equipment with more capable parts that are designed to carry greater weight. Replacing components such as springs and shock absorbers allows the vehicle to carry additional weight, without compromising on its handling, function and safety features. Of course, to ensure this is the case, all GVM upgrades are rigorously tested and approved by the Department of Infrastructure, Transport, Regional Development, Communications and Arts. During the GVM upgrade process, axle load limits are also commonly tested and validated to increase the permissible load over each axle.

WHY DO I NEED A GVM UPGRADE?
A popular dual cab ute weighs 2280kg off the showroom floor with no fuel, passengers or accessories. That same vehicle has a total payload of 920kg which results in a Gross Vehicle Mass (GVM) of 3200kg. While 920kg is a solid amount of payload, it is not uncommon to quickly use it all - and then some. Being over GVM is surefire way to endanger yourself passengers and other drivers. With fines of over $1000 & demerit penalties as well as voiding of insurance. GVM upgrades are a no brainer if you’re overloaded.
PRE-REGISTRATION VS POST REGISTRATION?
If a GVM upgrade is installed on a vehicle before it is first registered (preregistration), the GVM upqrade carries Federal approval. This means that the upgrade is recognised in all states and territories of Australia and is transferrable with the sale of the vehicle into any state. A GVM upgrade can be applied to a vehicle after it is already registered (post registration), however, there are some additional steps which include the sign off from an independent engineer and the GVM upgrade is not transferable on the Sale of the vehicle into any other state.
HOW DO YOU FIT A GVM KIT?
Sorry DIYers however this isn’t a job you can do yourself, all GVM upgrade kits must be fitted by an Ironman 4x4 approved GVM installer. The work then needs to be signed off by an independent automotive engineer in order to issue a compliance certificate. Luckily this entire process can be completed by us here at 4WH, call today to book 1300 791 058 or get a quote!
