Toyota Hilux
GVM Upgrades
Busselton
We do certified GVM upgrades on both the N80 and the new N90 Hilux. Two generations, two figures, and the one that suits yours is further down the page.
Why Hilux Owners Choose to Upgrade
Whether you're a tradie, caravan tower, or weekend warrior, chances are your Hilux is carrying more than it's legally rated for. Overloading your Toyota Hilux without a certified GVM upgrade can:
- Risk fines and insurance voiding
- Reduce braking effectiveness and stability
- Lead to long-term chassis and suspension damage
3,500KG to 3,740KG

One Thing To Know About The N90
The N90 upgrade is approved for pre-registration fitment, so the kit goes on before the Hilux is registered. It is worth sorting out when you order the vehicle rather than after it is on the road. If yours is already registered, get in touch anyway and we will tell you where it stands rather than have you guess.

Not just about load, we also offer Hilux lift kits for better clearance and off-road performance:
- Dobinsons Lift Kits (2" to 3" options)
- Tailored setups for tradies, campers, and tourers

(08) 9752 4466 2 Artisan Street, Busselton WA 6280The N80 is the 2015 on shape. The N90 is the new one. If you are not sure, send us the build date or the VIN and we will tell you which kit applies.
The N90 kit is approved for fitting before the vehicle is registered, so the ideal time is while the Hilux is still with the dealer. If yours is already registered, call us and we will let you know where it stands.
A Dobinsons GVM upgrade enhances your vehicle's legal weight-carrying capacity through the expert installation of a specially designed Dobinsons suspension kit. This kit, rigorously tested and approved in Australia by the Department of Infrastructure, replaces the factory springs, shock absorbers, and other standard suspension components. Additionally, tyre upgrades may be necessary. Unlike a standard aftermarket suspension kit, the Dobinsons GVM upgrade not only raises your vehicle's ride height from its original factory setting but also significantly boosts its payload capacity.
Check your manual or the placard on your vehicle for its GVM, then weigh your vehicle at a weighbridge loaded as you would normally drive it (caravan attached if you tow). If the total exceeds your GVM, you are overloaded. Visible rear suspension sag is another warning sign. Unsure? Our team is here to help.
Contact our friendly team. We will determine the best course of action and which suspension setup your vehicle needs.
Twin-Tube Shocks: the standard replacement at the lowest price point, a direct bolt-in for standard or raised suspensions. IMS Monotube Shocks: mid-range, adjustable, great for corrugated roads, long trips, off-roading and towing. Monotube Remote Reservoir (MRR) 3-Way Adjustable: the top-tier option with reduced shock friction and improved ride and damping performance.
Yes, we can do a 2" lift with the GVM upgrade.
Currently, the Department of Infrastructure and Transport does not endorse or approve upgrades to Gross Combination Mass. Dobinsons Spring & Suspension also does not endorse or approve any GCM upgrades.
