About this kit

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

Rough Country 97740 is a 3-inch lift kit for 2020–2026 Chevy Silverado and GMC Sierra 2500 HD and 3500 HD trucks, and the M1 monotube shocks come in the box — two pairs, front and rear. Your truck must have a rear overload spring; dually, AT4X, and ZR2 models are not covered.

A 3-inch lift kit for the 2020–2026 Chevy Silverado and GMC Sierra 2500 HD/3500 HD, this version ships the no-shock lift hardware together with two M1 monotube shock pairs, so damping is sorted at both ends without a separate order. Forged aluminum upper control arms arrive with ball joints already pressed in, and differential drop brackets limit how far axle angles move from stock. Everything bolts on without cutting and can be reversed to factory height later. Verify the rear overload spring, then rule out dually, AT4X, and ZR2 trucks with their 1.5-inch factory lift. A downloadable Rough Country installation guide is available.
