About the 7.5 Inch Lift Kit | Chevy/GMC 2500HD/3500HD (11-19)

Command Attention from the Start: Right off the lot, the GM 2500/3500HD commands attention with its aggressive stance and sharp style. Rough Country's 7.5" Suspension Lift was engineered to enhance this bold presence while keeping every factory advantage intact. Designed with a Non-Torsion Drop layout, this kit delivers improved ground clearance and handling without compromising your truck's factory angles or axle placement. Built with heavy-duty components, including 1/4" thick steel crossmembers, 1/2" thick NTD brackets, and a rugged skid plate, all laser-cut and finished in durable Hammer Black, this lift offers both strength and style. Installation is straightforward and non-invasive, requiring no drilling or differential modifications, so you can elevate your truck without altering its core mechanics.

Ride Smoothly with Factory Precision: Experience a ride that feels as smooth as stock with features engineered to retain factory quality. The Non-Torsion Drop design preserves proper torsion bar placement and stock track width, keeping your wheels aligned and handling predictable. Factory axle positioning is maintained to prevent premature wear, while the kit requires no changes to your drivetrain or exhaust. Fully configurable shock options allow you to dial in your ideal ride, with nitrogen-charged N3 shocks, upgraded M1 or V2 monotubes, or premium Vertex reservoir shocks available to suit your driving style and terrain.

Conquer Any Terrain with Confidence: Rough Country's 7.5" Suspension Lift gives your third-generation Chevy/GMC 2500HD/3500HD the perfect balance of aggressive off-road capability and factory-like comfort, letting you tackle tough terrain with confidence and style.
