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 CNC machining. They come with polyurethane frame pivot bushings, grease-able zerk fittings, and FK 1.25" PTFE-lined uniballs. The arms are powder-coated for durability and include all necessary hardware for installation. They are designed for 1-4.5" of lift and are not compatible with the Bronco Raptor.
