3.5-Inch Vertex Adjustable Coilover and Shock Lift Kit

The Rough Country 3.5-inch Lifted Knuckle Kit is engineered for 2007-2013 Chevy Silverado 1500 and GMC Sierra 1500 4WD vehicles, offering an aggressive stance and enhanced ground clearance without significantly compromising everyday drivability. It allows for the fitment of 33- to 35-inch tires while preserving the reliability of your factory suspension components. The kit includes 3.5" Cast Steel LCA Knuckles, precision-engineered to raise the CV axle position, thereby reducing stress and wear on the boots. It also comes with a 3.5" Kit Box, two Vertex 2.5" Adjustable Front Shocks with 10-stage variable valving and nitrogen charging for a balance of off-road capability and on-road comfort, and two Vertex 2.5" Rear Shocks with configurable damping. Installation of this kit requires cutting and grinding, and it is not compatible with aftermarket control arms. It specifically does not fit 2007 "Classic" Silverado 1500 or Sierra 1500 models. Vehicles equipped with a front differential mass damper will need it removed for adequate clearance. Additionally, a 0.25" wheel spacer (SKU: 1065) is required if you plan to retain factory wheels.
