Stage 2: ZR2 Only Performance Level-Up
Stage 2 of Offroad Industries' GVM program for the Chevrolet Silverado 1500 (LTZ, Trail Boss & ZR2) (2019–2026). “ZR2 Only Performance Level-Up” lifts the truck 2in (levelling kit or 2in lift option), clears LT275/70R18 (OEM), and re-rates it to 3650 kg GVM and 7850 kg (BTC 4200 kg) GCM — that's approx. 1087 kg (+44%) of legal payload.
Who it suits: ZR2 owners who want to keep the factory Multimatic shocks but get a legal 1-tonne payload.

Everything that goes into Stage 2
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.
