Description
Restore proper upper control arm performance on your 2011–2026 GM HD truck with the Axiom Supply Upper Control Arm Bushing Kit. Designed specifically for aftermarket UCAs from Cognito Motorsports, Kryptonite Products, and Axiom Supply, this kit replaces worn or failing bushings to bring back smooth articulation, improved handling, and consistent suspension alignment. Built from long-lasting materials, these bushings are engineered to handle the demands of towing, heavy-duty use, lifted setups, and off-road driving.
Over time, factory and aftermarket bushings wear out due to heat, impact, and constant suspension movement. When bushings deteriorate, you may notice clunking, alignment issues, uneven tire wear, or reduced ride quality. Axiom’s heavy-duty replacement kit eliminates these problems by restoring proper control arm support and reducing unwanted play. Whether your truck is leveled, lifted, or running high-mileage aftermarket arms, this kit provides the dependable performance and longevity your suspension deserves.
