About this kit
3.5-Inch Lift Kit with Vertex 2.5 and V2 Shocks, fitment-checked
Adjustable Vertex 2.5 shocks at the front, a V2 monotube pair at the rear, and 3.5 inches of knuckle lift for 2014–2019 Chevy Silverado 1500 and GMC Sierra 1500 4WD trucks. Knuckles are cut for stamped steel and aluminum lower control arms. Denali, Denali Ultimate, and eAssist trucks do not fit, and the install requires cutting and grinding.
A 3.5-inch lift kit for the 2014–2019 Chevy Silverado 1500 and GMC Sierra 1500 4WD that mixes damping families: adjustable Vertex 2.5 shocks up front, a V2 monotube pair at the rear. Knuckles machined for stamped steel and aluminum lower control arms set the height rather than taller springs, so the front end stays close to factory geometry. Before ordering, confirm the lower control arm material and rule out Denali, Denali Ultimate, and eAssist trucks. Cutting and grinding are required, a downloadable installation guide is available, and factory wheels need a 0.25-inch spacer, part 1065.
