Our Camburg upper arms are designed to address the limitations of stock upper arms when lifting your truck. By replacing the stock ball-joint with a larger 1.25 uni-ball bearing, we improve wheel travel and durability under extreme conditions. We also incorporate a billet aluminum cover to protect the uniball from dirt and contaminants. Our arms are designed using CAD/CAM engineering software and manufactured in-house with precision welding and machining. They come with polyurethane frame pivot bushings, FK 1.25" PTFE-lined uniballs, and all necessary hardware for installation. These arms are compatible with lifts of 1-3" and correct camber and caster.
