More about the Isuzu MU-X GVM upgrade
The MU-X is a popular family tourer, but its 2800kg factory GVM is low for a seven-seat wagon. The Lovells Touring kit lifts it to 3325kg, a 525kg increase.
GCM up from 5900kg to 6200kg
Front axle 1575kg, rear axle 1750kg
Braked towing stays at 3500kg
The factory 18-inch rims are not compliant with this upgrade, so you'll need rated wheels. We'll quote them with the kit. A family of five, a roof box, a bar and a fridge can put an MU-X close to its factory limit before you hitch a camper. The extra 300kg of GCM gives you room to do both.
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.
