Knowing how much of a load your vehicle is designed to carry or tow is crucial to both your 4WD’s efficiency and safety. You need to be aware of your vehicle’s payload and consider what loads you will be adding to your vehicle, taking into account passengers, luggage, accessories, etc and ensure your vehicle is kept within the limits stated on its compliance placard.
Here, we explain what you need to know to ensure your vehicle is both legal and safe.
All vehicle manufacturers set a maximum weight limit for their four-wheel-drive models; this is known as the Gross Vehicle Mass (GVM). Each manufacturer will also publish a tare (kerb) weight, which is the weight of the empty vehicle straight off the showroom floor. The vehicle’s payload is the difference between these two figures.
Example: GVM (3200kg) minus the tare (2300kg) = 900kg payload.
The easiest way to measure your 4WD GVM is by using your nearest public weighbridge. Available in all states, public weighbridges allow drivers to weigh their vehicles and trailers to get accurate figures on GVM, axle loads, trailer and tow ball weights.

ARB offers GVM and Axle Load Capacity upgrades for many new 4WD models. These federally recognised upgrades legally increase your vehicle’s total payload and axle weight limits by utilising certified, tested and uprated Old Man Emu suspension components. It’s important to speak with your local ARB store prior to registering your vehicle so the team can facilitate the federally recognised upgrade.
A certified Old Man Emu suspension package can increase total payloads significantly.
