About this kit
7-Inch Lift Kit, fitment-checked
Control arm material decides this one: Rough Country 18102 is a 7-inch lift kit for the 2014–2016 GMC Sierra 1500 Denali 4WD, and it fits only trucks with factory cast aluminum control arms — cast steel and stamped steel versions need a different kit. Magnetic Ride Control Denali models are the intended application.
The box holds driver- and passenger-side knuckles, a high-clearance crossmember, a strut spacer set, and fabricated rear blocks. Applications are limited to 4WD GMC Sierra 1500 Denali built 2014–2016 with Magnetic Ride Control and factory cast aluminum control arms. Cutting and drilling are required, and any mass damper on the front differential has to come off. Factory 20-inch wheels can stay on the truck, wheels must be at least 18 inches, and tires wider than 35x12.50 call for offset wheels and possible trimming. Shipping weight: 194.33 lb.
