Camburg Chevy Colorado ZR2 17-22 1.25in Performance Heim/Uniball Upper Arms (w/ covers)

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 incorporating larger and stronger FK 7/8" chromoly heim joints for additional camber and caster adjustment. The billet aluminum cover on top of the uniball prevents dirt and contaminants from entering. Our arms are meticulously designed using CAD/CAM engineering software and manufactured in-house with precision CNC laser cutting, bending, and MIG welding. They are then sandblasted and powder-coated for a durable finish. Our machined parts, including the uniball mis-alignment spacers, are made from heat-treated stainless steel in our CNC machine shop. The arms come with all necessary hardware and are designed for 1-2.5" of lift. They are specifically designed for ZR2 models and are made in the USA.
