About this kit
7-Inch Lift Kit with M1 Shocks, fitment-checked
This is the M1 build of Rough Country's 7-inch stamped-steel-LCA lift for the 2016–2019 Chevy Silverado 1500 and GMC Sierra 1500 4WD: M1 loaded struts up front, an M1 monotube shock pair out back, plus forged upper control arms, skid plates, and rear lift blocks. Denali, Denali Ultimate, and eAssist trucks are excluded, and the install calls for cutting and drilling.
The 7-inch lift kit for 2016–2019 Chevy Silverado 1500 and GMC Sierra 1500 4WD trucks, built around M1 monotube damping at all four corners. Crossmembers, a control arm drop kit, front and lower skid plates, a rear block box, and forged upper control arms round out what ships. Track width stays at factory spec and stock 20-inch wheels bolt back on. Fitment hinges on stamped steel lower control arms, so confirm what your truck has; Denali, Denali Ultimate, and eAssist models are out. Cutting and drilling are required, and a downloadable installation guide is available.
