ORI Chevrolet Silverado 2500HD SSM NB1 Stage 4: The Outlaw 5" Legal Monster

*Additional Costs may be incurred, contact for an official quote

Best for: The owner who wants that true "big truck" presence without the legal headaches. If you want a massive stance that is 100% legal, the Stage 4 package delivers a premium BDS 5" system with Fox 2.5 Performance Elite shocks, allowing you to run 37" tyres fully legal on a standard car licence under our pre-rego SSM (Second Stage Manufacture) approval.

Lift Height: 5 Inches
Tyre Size: Engineered specifically for 37-inch tyres.
Suspension Tech: Utilises a heavy-duty BDS 5" High-Clearance Kit, featuring a full replacement subframe drop and upgraded replacement steering knuckles to keep your factory steering geometry perfectly intact at the 5-inch ride height. ORI also includes the premium BDS upper control arms to give the front end a completely integrated, high-end look.
Shock Configuration: Fox 2.5 Performance Elite Series Shocks (front and rear) featuring remote reservoirs and adjustable damping. You can literally dial in the ride with a simple clicker—soften it up for a plush highway cruise, or firm it up for control on the tracks.
Extras: We also include colour-coded Husky Extenda Flares and ORI Metal mud flap brackets with rubber to ensure your vehicle is completely compliant and federally approved.
What's Not Included: Just your wheels and tyres! All you need to do is pick your style. We have already set the specific wheel offsets required to keep the build federally compliant, so there is no need to stress about load ratings or legality.

Stage 4: The Outlaw 5" Legal Monster

Stage 4 of Offroad Industries' SSM NB1 lift program for the Chevrolet Silverado 2500HD LTZ (2020–2026). It gives the truck a 5in (torsion; subframe drop + replacement knuckles) lift and clearance for 37in (37x12.5 or 37x13.5 R18/R20); zero offset, while keeping the vehicle at 4495 kg GVM — so it stays in the NB1 light-vehicle category and can still be driven on a standard car licence.

Who it suits: Big-truck presence on 37s, legal on a car licence via pre-rego SSM.
