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 uniball bearing, we improve wheel travel and durability under extreme conditions. We also enhance the vehicle's alignment and driving characteristics by adjusting the camber curve and adding more caster. Our arms feature stronger FK 3/4" chromoly heim joints for additional camber and caster adjustment, eliminating flexing and binding. Using advanced CAD/CAM engineering software and our FARO laser scan arm, we ensure precise design and fit. Manufactured in-house, our arms undergo CNC laser cutting, bending, MIG welding, sandblasting, and powder-coating. Machined parts, including uniball mis-alignment spacers, are made in our CNC machine shop using heat-treated stainless steel. Our arms increase usable wheel travel, correct camber and caster, and eliminate weak factory ball-joints. They are made in the USA and come with all necessary hardware for installation.
