GVM/GCM SUSPENSION UPGRADES
- GVM or Gross Vehicle Mass kits can be fitted to a wide range of vehicles
- Nationally Compliant - New vehicles never before registered, allowing the vehicle to have a GVM /GCM change and is recognised in all states.
- Federal Compliant - New vehicles.
- State Compliant – Registered vehicles fitted with GVM/GCM kits, requiring Engineer’s Certificate to be complied to state laws, recognised throughout Australia for travel
- We use only Lovells springs GVM kits
- Private weigh bridge to allow checking of total vehicle mass
The usable payload of many 4X4 vehicles today is minimal. Additional basic optional equipment and 2 or 3 adult male occupants will bring the vehicle close to its legal maximum weight (GVM) in many cases. Add long range fuel tanks, bull bars, winches, side steps, roof racks, recovery gear and camping equipment, or an industrial type custom body, and the vehicle will ultimately exceed the original equipment allowable gross vehicle mass.
Original equipment suspension is designed for comfort above all other considerations, thus load carrying, and performance can be compromised. Whereas, Lovells designs suspension systems with matched components to offer the ultimate in performance, load carrying, and handling.
Lovells GVM upgrade suspension kits are fully track tested in conjunction with a Certified Automotive Engineering Signatory over many days to achieve maximum stability, braking performance, ADR (Australian Design Rules) conformity, and operator comfort before test data and documentation are forwarded to the Department of Infrastructure, Transport Regional Development, and local government for full analysis.
The National Codes and laws that must be met are extremely stringent and it can take up to 6 months for all data to be analysed in full by the Road Safety Engineers in Canberra. Once the department is satisfied with all dynamic testing and theoretical data, it is only then that Lovells is issued with certification of secondary manufacture for GVM upgrades.
Lovells GVM upgrade kits provide a solution for owners/managers of Toyota LandCruiser, Toyota Hilux, and Nissan patrol vehicles who need to carry loads which exceed the original equipment GVM specifications, while at the same time meeting the practical and documentary compliance requirements of work safety, police licensing, insurance, lessors and fleet managers.

Frequently Asked Questions
What are GCM suspension upgrades?
GCM suspension upgrades increase your vehicle’s Gross Combined Mass, allowing you to safely tow heavier loads. These upgrades involve replacing suspension components to handle the extra weight while maintaining stability and performance. They’re essential for travellers, tradies and anyone towing caravans, boats or trailers.
Do I need GCM suspension upgrades for towing?
If your vehicle’s combined weight (vehicle + trailer) exceeds the factory GCM limit, you’ll need certified GCM suspension upgrades. Towing beyond legal limits is unsafe and can affect insurance or compliance. Upgrading ensures your vehicle remains road-legal and performs safely when fully loaded.
Are GVM & GCM upgrades the same?
No, GVM refers to how much your vehicle can carry, while GCM covers the total weight of the vehicle and what it’s towing. GCM suspension upgrades typically follow a GVM upgrade and ensure your suspension and drivetrain can manage heavier towing loads reliably and legally.
