2-4" Aluminum Upper Control Arm for 2007-2018 Chevy Silverado 1500 & GMC Sierra 1500 - KSP Performance, Polyurethane

<p>Upgrade the front suspension of your 2007-2018 Chevy Silverado 1500 or GMC Sierra 1500 with these forged aluminum upper control arms designed for trucks with 2 to 4 inches of lift. CAD engineered geometry helps address ball joint angle issues while restoring more appropriate camber and caster after lifting, and the arm shape is designed to maintain shock clearance through suspension travel. Each control arm is CNC machined from 6082 aluminum alloy, providing high structural stiffness, reduced weight, and natural corrosion resistance without relying on a protective coating. The aluminum construction will not rust like steel, making it well suited for trucks exposed to moisture, snow, and road salt. Greaseable ball joints come pre greased for installation and are fully replaceable for easier long term service. Rubber and polyurethane bushing options are available to match different ride and maintenance preferences. The package includes two control arms, three ball joints, two logo plates, mounting hardware, and instructions. Fits 2007-2018 Silverado 1500 and Sierra 1500 2WD and 4WD models. Does not fit stock height, 2007 Classic, or 3.5 inch lifted knuckle applications, and stock wheels require spacers to prevent control arm rubbing. </p>
