How to use this calculator (Click to expand)

Start at the top: Select your Make, Model, and Variant to load the factory weight specifications automatically.
Load your passengers: Adjust the "Occupants" settings. Note: We automatically include a driver (85kg) by default.
Add your gear: In the "Installed Equipment" section, select your accessories (bullbars, winches, roof racks).

Tip: If your exact brand isn't listed, select a similar item or "Generic" to get a realistic weight estimate.

Check your suspension: If you have a GVM upgrade kit fitted, select the brand in the "GVM Upgrade" section to update your legal limits.
Watch the Traffic Lights:

🟢 Green: You are compliant.
🔴 Red: You have exceeded a limit (Total GVM, Front Axle, or Rear Axle).

Balance the load: Watch how adding weight to the rear (like a tow ball load) lifts weight off the front axle. Try moving items forward to turn the red lights green.
