About this kit

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

Rough Country 95640RED is a 3 inch lift kit for the 2020-2026 Chevrolet Silverado 3500 HD and GMC Sierra 3500 HD, in 4WD or RWD. It pairs red forged upper control arms with two M1 monotube shock pairs. Dual rear wheel models only, and only trucks equipped with rear overload springs.

This 3 inch lift kit for the 2020-2026 Chevrolet Silverado 3500 HD and GMC Sierra 3500 HD raises the front 3in and the rear 2.5in, which brings the nose up level with the back of the truck. Fitment runs across WT through High Country on the Chevrolet side and Pro through Denali Ultimate on the GMC side, in 4WD and RWD. Confirm you have dual rear wheels and factory rear overload springs first. The forged, indexed torsion bar keys and rubber-bushed upper control arms bolt on with no cutting, drilling, or welding, and a downloadable installation guide is available.
