Frequently asked questions

Yes, there are legal requirements and regulations for GVM upgrades. JMACX does extensive testing on all our GVMs to ensure that your vehicle remain safe and legal while increasing your vehicles capability.

Yes, JMACX offers multiple GVM upgrades for the 4 cylinder 76, 78, 79 Series Landcruiser from 3900Kg to 4495Kg.

Federal approval is done prior to first registration (pre rego). This vehicle is then registered as a vehicle manufactured by the GVM provider i.e. no longer a Toyota Landcruiser. This is called a Second Stage Manufacture (SSM). These vehicles must be provided at first registration with no other modifications other than the specific approved GVM kit. This vehicle is compliant in all States and does not require any further engineering unless modified outside its original design.

State approval is done post registration in your applicable State. Even though an SSM approval can be applied to a post register car there may be some restrictions due to State legislation. For example lift height, tyre size, GCM and BTC increases. Recommended to check with your State legislation for compliance. All GVM upgrades post registration only apply to the State your vehicle is registered in. If you try to register the vehicle in another state you will be required to be re-engineered in that State.

  • Toyota: 70 Series GVM Upgrades: 79 Series dual cab and single cab, 78 Series (Troop Carrier), 76 Series (Wagon), 200 Series, 300 Series
  • Dodge: Ram DS 1500, Ram DT 1500
  • Ford: Ranger Next Gen

Adding an upgraded diff housing with a higher rating e.g. 3,000Kg does not automatically increase your axle load capacity to 3,000Kg. The diff housing upgrade is only one piece of the equation. To achieve an increased axle capacity requires not only axle load but also springs and shocks engineered to carry and control the weight. Load rated wheels and tyres are also required. Axle load capacity is fixed by the GVM provider. Adding a higher rated differential will not give you an increased usable axle load if the GVM states a lesser axle load.
