FORMULA GCM Upgrades for Vehicle

7500kg Formula 4x4 GCM Upgrade to suit LandCruiser 300 Series 2021-on

7500kg Formula 4x4 F4R GCM Upgrade Kit to suit Toyota 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.
