If you regularly tow, go 4W driving or load your ute up with heavy equipment, understanding the GVM of your vehicle is an important factor in keeping you safe on the road and ensuring that you are following all regulations with your vehicle. GVM (Goss Vehicle Mass) is the maximum weight allowed for a vehicle when it is fully loaded. At AME Automotive, we are Perth’s experts in GVM upgrades. Here is our guide to understanding GVM and GVM upgrades.

Complying to the GVM of Your Vehicle

To check if you comply with GVM requirements, you can calculate how much weight your vehicle is carrying. Start with the base weight of the vehicle, and then include added weight from any and all of the following:

  • Cargo
  • Fuel
  • Passengers
  • Tray body (for cab-chassis models)
  • Tow-ball load exerted by caravans, boats, etc – if you’re towing a boat, you don’t have to add the actual weight of the boat. However, simply towing something behind your vehicle is going to exert more weight at the tow point and this extra weight must be taken into consideration.

GVM Requirements in Australia

All vehicles have their requisite GVM standards that the vehicle owner or driver is required by law to uphold. If you’re caught driving a vehicle loaded beyond its legal GVM, you could be sacrificing your safety, you could face serious fines and your insurance may not cover you. The good news is that you can upgrade your GVM and it is a relatively easy and affordable process.

Reaching Your Maximum GVM

Reaching or exceeding your GVM is actually quite easy to do. When your vehicle is fully loaded for a journey or if you are a tradesperson constantly carrying tools and equipment, your vehicle may be overloaded beyond its GVM and payload capacity and you may not even know it. A vehicle can reach its GVM when fitted with a steel tray and toolboxes or with two or more large adults riding in the vehicle. Knowing this, it is important to be aware of your GVM and the weight that you are carrying in your vehicle. A GVM upgrade will prevent you from unintentionally passing your maximum limit, and ensure the safety of your vehicle is not compromised.

What’s Involved in a GVM Upgrade?

Upgrading your GVM requires fitting a new, stronger suspension system to the vehicle. The brakes and axles should be in good condition – an approved engineer will need to check the compliance plate and individual axle weights on your vehicle before any modifications can be done. Once testing and inspection has been completed, a GVM upgrade kit can be fitted to your vehicle. When the GVM upgrade kit has been installed the vehicle will be inspected by an authorised automotive engineer in your state and you will be issued with a compliance certificate.

Is My Vehicle Warranty Affected When Fitting A GVM Upgrade?

Vehicle warranty is not affected when a GVM upgrade is fitted. Stringent testing procedures are performed after the upgrade to ensure equipment components are not compromised. All GVM modifications undertaken by AME Automotive are within theoretical service/safety factors to ensure the integrity and longevity of the parts associated with increasing the vehicles load carrying capabilities. 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, contact the experts at AME Automotive today. We can inspect your vehicle to determine the overall weight and advise you if a GVM upgrade is the best option for your vehicle.
