Toyota LandCruiser 78 GVM Upgrade (3900kg) - Lovells
Toyota LandCruiser 78 GVM Upgrade (3900kg) - Lovells
The 78 Series Troop Carrier is commonly set up for touring with storage systems, long-range fuel and roof loads, which can quickly exceed the factory payload. Even moderate builds can run out of legal capacity once fully equipped.
This 3900kg GVM upgrade is suited to vehicles carrying moderate constant load. It’s a practical option for touring setups that need additional capacity while maintaining predictable handling across varied conditions. This upgrade also allows for an increase in GCM where applicable, supporting higher combined vehicle and trailer weights.
