ORI GVM & Lift Packages

Offroad Industries GVM & Lift Packages

Straight from GMSV, the Silverado 2500HD is rated at 4,495 kg GVM — only around 733 kg of payload for a truck that weighs close to 3.8 tonnes before you add a tray, canopy, water and fuel.

Offroad Industries' NB2 packages raise GVM to as much as 6,000 kg while keeping the 12,474 kg GCM. Their SSM NB1 lift packages give you 3–6.5" of lift on 37s and keep the truck on a car licence. We supply, fit and certify every stage at our Smeaton Grange workshop.

Factory rating: 4,495 kg GVM (NB1) · 12,474 kg GCM · about 733 kg payload

Prices are for packages supplied, fitted and engineered. Post-registration upgrades attract extra state engineering and registration fees. Some stages need load-rated wheels and tyres. Offroad Industries (ORI) is an independent Australian brand; Project Overlander is an authorised installer.

Project Overlander fits the full range of accessories for your Chevy 2500HD — wheels and tyres, lighting, racks, awnings, Starlink and complete touring fit-outs.
