Land Cruiser 78 & 79 Series
GVM Upgrade
The Land Cruiser 78 and 79 Series are widely used for touring, trade work and remote travel, but tray setups, the Troop Carrier body, accessories and towing weight can quickly push either toward its factory limit.
A GVM Upgrade Increases Legal Load Capacity
A GVM upgrade increases the legal load capacity, helping the vehicle safely carry equipment and accessories. This increased rating supports heavier loads such as tray builds, canopy setups, long range tanks, recovery equipment and caravan towing.

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.
