Everything that goes into Stage 4
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.
