About this kit
5-Inch Lift Kit with M1 Shocks, fitment-checked
Rough Country 110840 is a 5-inch non-torsion-drop lift kit for compatible 2020–2026 Silverado 2500 HD/3500 HD and Sierra 2500 HD/3500 HD trucks, built around a laser-cut crossmember, new driver and passenger knuckles, and two pairs of M1 monotube shocks. It fits only trucks with rear overload springs, and it will not work with dually, AT4X, or ZR2 models or with factory wheels.
This 5-inch lift kit for the 2020–2026 Chevrolet Silverado 2500 HD and GMC Sierra 2500 HD uses a non-torsion-drop design, so the front end gains height through a bolt-in crossmember and replacement knuckles rather than by cranking down the torsion bars. Track width and axle geometry stay where the factory put them, and no differential drilling is called for. Gas trucks may need exhaust clearance work for the driveshaft. Confirm your truck has rear overload springs and aftermarket wheels before ordering, then pull the downloadable Rough Country installation guide to plan the job.
