Silverado 2500: 6.5" Lift And 37s, NB1 Approved - No Truck Licence Required

If you've been holding off on a serious Silverado 2500 build because you didn't want to cross into truck licence territory, Offroad Industries just removed that excuse.

Offroad Industries newly approved package allows owners to legally run up to a 6.5-inch suspension lift and 37-inch tyres while retaining NB1 classification, meaning the vehicle can still be driven on a standard car licence.

While large GVM upgrades, 37-inch tyres and substantial suspension lifts are already available for the Silverado 2500 platform, those packages typically push the vehicle beyond 4,500kg GVM and into the NB2 category, requiring a Light Rigid (LR) licence to drive.

This new package takes a different approach.

Rather than chasing maximum GVM, the focus is on retaining NB1 classification while still delivering the aggressive stance, ground clearance and off-road capability many Silverado owners are looking for.

The package is pre-registration only, federally approved, and developed here in Australia. Full package details including pricing, and variant compatibility haven't been released.

Why NB1 Matters So Much Here

For many buyers, the biggest barrier to stepping into an American heavy-duty truck isn't the size of the vehicle - it's the licensing requirements on NB2.

What ORI has done with this Silverado 2500 kit is get 6.5 inches of lift and 37-inch tyres federally approved while keeping the vehicle in the NB1 car licence category. At that lift height, most people assume you're crossing into NB2 territory. This approval says you don't have to.

For customers who don't need a 6-tonne GVM upgrade but still want the biggest practical suspension and tyre package available, this could be an attractive alternative.
