Boost your Landcruiser’s carrying capacity and safety with the LTG 4×4 3900kg GVM Upgrade Kit. Engineered for HDJ100 and UZJ100 models, this kit increases the factory GVM from 3260kg to 3900kg, delivering the strength and stability needed for towing, touring and heavy accessories.

Key Features

• GVM increase to 3900kg (+640kg)
• Heavy‑duty rear axle housing rated 2500kg with fully floating bearing conversion
• Induction‑hardened 2‑piece axles with drive plates
• HD shocks, HD rear coils (2” lift) & HD front torsion bars
• Poly‑Air Ultimate rear airbag kit included
• ABS sensor & loom change‑over plus full seal & hardware kit
• Direct bolt‑in fitment—no modifications required
• Comprehensive engineering report supplied for compliance

Fitting time typically takes 18–20 hours, as the process involves removing the original rear axle housing, fitting the new heavy‑duty 2500kg‑rated assembly, installing all suspension components and airbags, completing the ABS loom change‑over, and performing final torque checks and a road test. The overall time can vary based on factors such as the condition of existing hardware, corrosion, or the presence of accessories that limit access, like long‑range tanks or rear bars.
