About this kit
5-Inch Lift Kit with M1 Shocks, fitment-checked
Two M1 monotube shock pairs give this 5-inch heavy-duty kit its ride, working with torsion bar drop brackets, a crossmember, and driver and passenger knuckles. Covers 2020–2026 Silverado 2500 HD and 3500 HD and Sierra 2500 HD and 3500 HD in 4WD and RWD. Dually trucks, trucks with rear overload springs, AT4X, and ZR2 are not covered, and factory wheels will not work.
The front end drops on torsion bar brackets, which keeps the axles at their factory position and angle and means no drilling or modification of the differential. Damping is handled by two M1 monotube shock pairs, one front and one rear, and the kit also carries a crossmember and driver and passenger knuckles. Fitment covers 2020–2026 Silverado 2500 HD, Silverado 3500 HD, Sierra 2500 HD, and Sierra 3500 HD in 4WD or RWD. Dually trucks, trucks with rear overload springs, AT4X, and ZR2 are excluded. Factory wheels will not work, and gas trucks may need exhaust modification for driveshaft clearance.
