About this kit
3.5-Inch Lift Kit with M1 Monotube Shocks, fitment-checked
M1 monotube damping is what sets this kit apart: Rough Country 110440 combines an M1 loaded strut pair, an M1 monotube shock pair, and forged aluminum upper control arms to lift a 2025-2026 Chevy Silverado 1500 3.5 inches in front and 2.5 inches at the rear.
Run the numbers before you order. This 3.5-inch lift kit is written for 2025-2026 Chevy Silverado 1500 4WD and RWD trucks across the Custom, High Country, LT, LTZ, PPV, RST, and WT trims, and the M1 monotube strut and shock pairing is the reason to choose it over the N3 build. Forged aluminum upper control arms carry pre-installed POM ball joints. The install calls for cutting and drilling, so set aside driveway time. Trail Boss, ZR2, and Adaptive Ride Control trucks are outside the fitment. A downloadable installation guide is available.
