About this kit
5-Inch Lift Kit, fitment-checked
This 5-inch kit is the cast-steel counterpart in Rough Country's Denali range (part 18300). It fits 2014–2018 GMC Sierra 1500 Denali and 2017–2018 Sierra Denali 4WD equipped with factory cast steel knuckles or control arms and Magnetic Ride Control, and allows 33-inch tires on factory 20-inch wheels.
A steel control arm knuckle, a crossmember box, and the front component set do the lifting here, with fabricated rear blocks in place of cast. Applications are 4WD GMC Sierra 1500 Denali from 2014–2018 and Sierra Denali from 2017–2018, restricted to trucks with factory cast steel knuckles or control arms and Magnetic Ride Control. Cutting and drilling are required. Run 18-inch or larger wheels, remove the front differential mass damper if the truck has one, and expect offset wheels and possible trimming past 33x12.50. Shipping weight: 158 lb.
