GVM/GCM Upgrades

CHEVY SILVERADO 2500HD 2020 - 2026

Shatter your payload limits and command the outback without compromise with a Silverado 2500 GVM upgrade. Offroad Industries (ORI) delivers Australia’s ultimate, fully Federally Approved GVM upgrades for the Chevrolet Silverado 2500HD range. Our SSM approvals only apply to GMSV Vehicles. We cannot do private imports.

The ORI Advantage:

  • Massive Stance: Options ranging from a sleek 3” lift up to our monster 6.5” package on 37” tyres.

  • NB2 Upgrades Made Easy: A seamless, ORI-approved pathway from NB1 to the heavy-duty NB2 category via VTA-065187 or we can upgrade NB2 to NB2 via our VTA-065796

  • Bulletproof Compliance: Rigorously tested and backed by Federal SSM Certification.

Backed by punishing testing and uncompromising Federal SSM Certification, an ORI GVM Package doesn't just upgrade your Silverado; it takes it to true "Super-Truck" status. Operating under exclusive ORI Vehicle SSM Approvals, we provide a streamlined, zero-headache pathway to reclassify your rig from an NB1 to a heavy-hitting NB2 category.

The result? Your fully loaded truck, all your gear, and that 4.5T trailer in tow are 100% compliant, secure, and road-legal nationwide when completed Pre-Rego (Federal). Why not invest in your brand new Chevy Silverado 2500HD now?
