About this kit
3.5-Inch Lift Kit, fitment-checked
A 3.5-inch lift for the 2014–2016 GMC Sierra 1500 Denali 4WD, Rough Country 18901 fits only Denali trucks with Magnetic Ride Control and factory cast aluminum or cast steel upper control arms. Forged upper control arms with pre-pressed ball joints come in the kit, and a new lift block takes the place of the factory unit.
Compared with the taller kits in this family, 18901 keeps the parts count low: forged upper control arms rated for 2.5 to 3.5 inches of lift, spacer hardware, and a replacement rear block. It suits 2014–2016 GMC Sierra 1500 Denali 4WD trucks with Magnetic Ride Control, and it will not work on 2016 or newer trucks running stamped steel factory upper control arms. Cutting and grinding are required, any front-differential mass damper has to come off, and factory wheels can be retained with a 0.25 in spacer, part number 1065.
