About this kit
3.5-Inch Lift Kit with M1 Monotube Shocks, fitment-checked
M1 monotube damping front and rear: Rough Country 110540 pairs an M1 loaded strut pair with an M1 monotube shock pair and forged aluminum upper control arms, lifting a 2025-2026 GMC Sierra 1500 3.5 inches in front and 2.5 inches at the rear.
Step up from the N3 build and this is what changes — M1 loaded struts up front and an M1 monotube shock pair at the rear, matched to forged aluminum upper control arms with POM ball joints installed. The kit takes a 2025-2026 GMC Sierra 1500 to 3.5 inches of front lift and 2.5 inches behind, across Elevation, Pro, SLE, and SLT trims in 4WD and RWD. Denali and Denali Ultimate trucks carry Adaptive Ride Control and are excluded, as are AT4, AT4X, and diesel models. Cutting and drilling are required. A downloadable installation guide is available.
