About this kit
3.5-Inch Loaded Strut Lift Kit, fitment-checked
Cast steel lower control arms, 3.5 inches of lift, and a pair of loaded strut assemblies that go in as finished units — that is the shape of 12432 for 2014–2019 Chevy Silverado 1500 and GMC Sierra 1500 4WD trucks. Verify the control arm material before ordering. Denali, Denali Ultimate, and eAssist trucks are outside the fitment, and the install calls for cutting and grinding.
Aimed at 2014–2019 Chevy Silverado 1500 and GMC Sierra 1500 4WD trucks with cast steel lower control arms, this 3.5-inch lift kit combines the knuckles with a matched pair of loaded struts, so the front corners bolt in as complete assemblies. The knuckle approach raises the CV axle away from the lower arm and leaves factory geometry largely untouched. Cast aluminum and stamped steel arms need a different part, so confirm yours first, and check that the truck is not a Denali, Denali Ultimate, or eAssist model. Cutting and grinding are required; a downloadable installation guide is available.
