More about the LandCruiser 79 Series (J7) GVM upgrade
The J7 79 Series covers both the V8 and the 2.8L four-cylinder, and Lovells kits suit both. Factory GVM is 3510kg. Lovells kits go to:
Comfort – 3900kg GVM, GCM 7010kg
Touring – 3900kg GVM, GCM 7400kg
Touring or Platinum – 4200kg GVM, GCM 7400kg, rear axle 2550kg
Elite – 4495kg GVM (single cab): Lovells track-corrected rear diff housing with billet axles, Platinum remote-reservoir shocks and a 2850kg rear axle rating
The 4200kg kit needs tyres with a minimum load index of 117 on factory wheels, or it can be derated to 3900kg on factory tyres. For tradies and tourers carrying a tray, canopy and water, the extra rear axle rating is what makes the difference.
GVM, GCM and towing: what the numbers mean
GVM (Gross Vehicle Mass) is the most your vehicle is allowed to weigh, fully loaded. That covers the vehicle, fuel, passengers, accessories, everything in the tray or cargo area, and the towball weight of anything you're towing.
GCM (Gross Combination Mass) is the most your vehicle and trailer can weigh together. It's often the limit people forget.
Braked towing capacity (BTC) is the heaviest braked trailer your vehicle can tow, measured at the trailer's loaded weight (ATM).
A bull bar, winch, drawers, a canopy, a second battery, a long-range tank, a roof rack and a full fridge can add 400–600kg before you've packed a bag. Many 4WDs and utes go over their factory GVM before they leave the driveway on a trip.
Why GCM matters when you tow
GCM caps the car and van together. Take a vehicle with a 5900kg GCM towing a 3500kg caravan: the car itself can only weigh 2400kg, loaded. That's often less than the car plus passengers, fuel and accessories. A Lovells GCM revision raises that combined limit, so you can tow the van and still carry your gear legally.
Pre-registration or post-registration?
Pre-registration: fitted to a new vehicle before it's first registered. The vehicle is re-certified as a second-stage manufacture with its new ratings, which are recognised in every state. If you're buying new, this is the cleanest option.
Post-registration: fitted to a vehicle already on the road. In Victoria the upgrade is inspected and certified by a licensed VASS engineer.
Either way, tell your insurer about the upgrade. Our team will tell you which option suits your vehicle and handle the paperwork.
