7500kg Formula 4x4 GCM Upgrade to suit LandCruiser 300 Series 2021-on
The Formula 4x4 GVM upgrade for the Land Cruiser 300 Series includes a 4.5t rated Hayman Reese tow tongue. If towing greater than 3500kg a 70mm tow ball or a CruiseMaster DO45 coupling is required, either have been approved for towing up to 4500kg. These can be supplied separately if required through any Fulcrum store.
This combination is specifically required because these components are engineered to support the full Gross Combination Mass (GCM) limits of the combined vehicle & load, ensuring the mechanical "credit" meets the high demands of heavy-duty towing. Other rated components equivalent to the 70mm ball or DO45 may be used if they meet the specific rating requirements.
Please note that while we provide these technical recommendations for compliance and safety, the customer remains responsible for ensuring the final configuration matches their specific trailer requirements and that they operate within the legal GCM limits at all times.

For pre-rego vehicles (before the vehicle is registered) there is no charge for this service.
For post-rego vehicles (vehicles that are already registered) there is an additional cost for this as the data for your already registered vehicle needs to be changed and a new mod plate needs to be assigned to the already registered vehicle. When purchasing this GVM kit from us on our website we allow you to choose whether your vehicle is post/pre rego and also showing the related engineering costs.
GVM Lift Kit
Upgrade your 4WD’s load-carrying capacity, ride height and suspension performance with a professionally engineered GVM Lift Kit.
A Gross Vehicle Mass, or GVM, upgrade increases the maximum permitted operating weight when the kit is correctly installed, inspected and certified. This provides additional capacity for passengers, permanent accessories, tools, touring equipment and other essential loads.
Unlike a standard suspension lift, a GVM Lift Kit is developed as a complete suspension package. Matched springs, shock absorbers and supporting components work together to improve load control, ride quality, stability and handling on sealed roads, corrugations and off-road terrain.
Key Benefits
- Increased legal load-carrying capacity when approved and certified
- Improved ride height and ground clearance
- Better stability and body control under load
- Reduced suspension sag with correctly matched springs
- Improved handling across touring, towing, work and off-road conditions
- Heavy-duty springs and matched shock absorbers
- Application-specific components for reliable performance
Correct spring selection is essential. Permanent accessories and constant loads, including bull bars, winches, batteries, canopies, drawers, tools and recovery equipment, must be considered when configuring the kit.
After purchase, a Fulcrum Suspensions specialist will confirm your suspension setup, permanent load, towing requirements and intended use before processing the order.
Professional installation, wheel alignment and certification are required. A GVM upgrade does not increase Gross Combined Mass, axle ratings or towing capacity unless specifically included in the applicable approval.
Increase your carrying capacity with a suspension package engineered for the job. Order your GVM Lift Kit today, and our team will confirm the correct configuration before installation.
