Optimize your Chevrolet Silverado 1500 alignment and upgrade its front-end components with Supreme Suspensions® Upper Control Arm and Camber/Caster Lock-Out Kit. Rigorously tested by in-house ASE certified specialists, this set of upper control arms is made from 4130 Chromoly Steel and engineered to correct the camber and caster adjustments on your lifted pickup truck. This tubular control arm kit is equipped with Zerk Fittings to easily grease the included Polyurethane Bushings and Teflon-Coated FK 1.25" PTFE-Lined Uni-Ball Bearings to replace the weak factory upper ball joints, offering unparalleled strength for heavy-duty or off-road use.

Designed to replace the upper control arm’s left and right OEM slotted eccentrics, Supreme Suspensions Caster/Camber Adjusting & Lock-Out Kit includes all necessary hardware required to ensure proper alignment and prevent any sudden and extreme changes in alignment cam position. Each cam plate is precision CNC Laser Cut from 3/16" Steel and designed with seven alignment holes to keep the alignment locked in place and prevent unwanted changes caused by off-road driving, worn eccentrics and / or lost locating pins.

Note: *An alignment is always recommended if you are altering the height of your vehicle.
