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 1.50 uni-ball bearing, we improve wheel travel and durability under extreme conditions. We also adjust the camber curve and increase caster to correct geometry, resulting in improved driving characteristics and handling. Our arms are designed using CAD/CAM engineering software and manufactured in-house with precision. They feature thicker .156" wall round tubing, laser-cut and CNC-bent tubes, and MIG welding. The arms come with polyurethane frame pivot bushings with grease-able zerk fittings, FK 1.50" PTFE-lined uniballs, and steel gray powder-coating. All necessary hardware is included for installation. The arms are made in the USA and designed for 1-3" of lift, compatible with 2008-2022 Toyota Sequoias. Additionally, this suspension system is not compatible with 20" OEM wheels & tires and 18" OEM wheels with larger tires than stock.
