GVM Upgrades

GVM & GCM Explained (+ GVM Upgrade Solutions)

GROSS VEHICLE MASS

Whether you’re carrying tools of the trade or packing up the 4×4 for an extended trip, your vehicle can become dangerous and illegal if it exceeds the allocated gross vehicle mass (GVM).

The GVM is the maximum a vehicle can weigh when fully loaded. Everything you place on or in your vehicle adds to the overall GVM – fuel, accessories, cargo (including passengers), the tray body for cab chassis models, and even the tow ball load applied by a boat or camper trailer.

GVM UPGRADES

New vehicle GVM upgrades are only granted by the Federal Department of Infrastructure and Transport after detailed tests have been carried out by Old Man Emu Suspension Engineers. We ensure that the increase in a vehicle’s GVM following the fitment of a complete suspension system meets the minimum ADR safety requirements.

Once the approved suspension system and GVM upgrade compliance plate has been fitted to your vehicle by an authorised Old Man Emu installer, it can be registered according to its new, increased GVM. This process ensures that your vehicle is GVM legal in all states of Australia.

Already registered vehicles fall under the jurisdiction of their state authorities. The need for GVM upgrades post-registration should be discussed with your local ARB State Office, as regulations differ between states and other requirements may be imposed locally.

OLD MAN EMU FRONT AXLE LOAD UPGRADES

The final weight over the front axle of your vehicle is often determined by the weight over the rear axle, as more rear axle weight will reduce the downward pressure over the front axle. Therefore loading and unloading of weight on the rear of a vehicle, such as unhitching a trailer or removing your touring gear, can play havoc with weight distribution across your front axles in accordance with the manufacturer’s front axle load limits.

To assist in providing greater flexibility in managing load variations as you need, ARB offers a range of Old Man Emu front axle capacity upgrades for the most popular 4×4 models when installing an Old Man Emu suspension package. With up to an additional 170kg of verified front axle load, tourers and tradies alike can have peace of mind that dynamic shift in weight distribution is being aptly supported across both axles.

AVAILABLE FRONT AXLE LOAD UPGRADES

ARB’s front axle load upgrades are standard with any full Old Man Emu Nitrocharger or BP-51 Suspension kit and are demonstrated by certification attached to your vehicle’s door pillar, owner’s manual and customer handover pack. Current customers of the applicable vehicles can also organise through their local ARB store to have their vehicle assessed for compliance.
