GVM 4495 kg (stays NB1) | GCM 12,474 kg
Stage 1: The Weekend Warrior 3in Upgrade
Stage 1 of Offroad Industries' SSM NB1 lift program for the Chevrolet Silverado 2500HD LTZ (2020–2026). It gives the truck a 3in (BDS kit: diff drop, sway bar relocation, rear blocks) lift and clearance for 35in or 37in (35x12.5 / 37x12.5 R18/R20); wheels 1100 kg rated, +12/+18/0, while keeping the vehicle at 4495 kg GVM — so it stays in the NB1 light-vehicle category and can still be driven on a standard car licence.
Who it suits: Daily drivers wanting a legal 3in lift on 35/37s without needing a truck licence.

Why get it fitted by Project Overlander
Fitted in-house
Your package is installed by our own technicians at Smeaton Grange — the same team that builds our full American truck touring setups.
Engineering handled
We take care of the ORI approval paperwork, plates and certification, whether the truck is pre-registration or already on the road.
Build it once
Pair the upgrade with trays, canopies, long range tanks, awnings and 12V from the same workshop — one booking, one warranty contact.
Price is for the package supplied, fitted and engineered. Post-registration upgrades attract additional state engineering and registration fees. Some stages need load-rated wheels and tyres. Final specification is confirmed at quote, based on your vehicle's build and compliance plates. Offroad Industries (ORI) is an independent Australian brand; Project Overlander is an authorised installer.
