Stage 6: The Six Inch Build - Top of the Range
Stage 6 of Offroad Industries' GVM program for the RAM 2500 6th Gen (2025+). “The Six Inch Build - Top of the Range” lifts the truck 6in, clears 40x13.5 R17 (load-rated wheels + 1650 kg tyre rating required; offsets +12/0/-11), and re-rates it to 5890 kg (NB2) GVM and 12,750 kg GCM — that's 2060 kg of legal payload.
Who it suits: The most heavily built 6th Gen rigs wanting 40in tyres, fully engineered.
Note: ORI expects federal approval for the 6th Gen packages shortly. Talk to us now to lock in a build slot.

Everything that goes into Stage 6
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.
