About this kit

3-Inch Lift Kit with M1 Shocks, fitment-checked

Rough Country 95640 is a 3-inch lift kit for the 2020–2026 Chevrolet Silverado 3500 HD and GMC Sierra 3500 HD in 4WD or RWD. It raises the front 3 inches and the rear 2.5 inches to bring the nose level with the back. Dual rear wheel models only, and only trucks equipped with rear overload springs.

This 3-inch lift kit for the 2020–2026 Silverado 3500 HD and Sierra 3500 HD covers listed trims from WT and Pro up through High Country and Denali Ultimate, in both 4WD and RWD. Two M1 monotube shock pairs, forged upper control arms, and indexed forged torsion bar keys make up the package, so factory-like front geometry and full suspension travel are retained without stressing OE parts. Installation bolts on with no cutting, drilling, or welding. Confirm your truck is a dual-rear-wheel model with rear overload springs, then work from the downloadable Rough Country installation guide.
