Symptoms
A bull bar, winch, roof rack, fridge and two adults put the truck over its factory gross vehicle mass of 1,435–1,450 kg.
The fix, step by step
- Fit a federally approved GVM kit with matched springs and shocks.
- Ironman's kit raises GVM from 1,435 kg to 1,785 kg (axle limits 800 kg front, 1,100 kg rear) and lifts the truck 45 mm; TJM's XGS GVM+ goes to 1,800 kg.
- Fitted before registration, the truck gets a new compliance plate.
- Fitted afterward, a state-approved engineer must inspect it and issue a modification plate.
