1.25″ Performance Uniball Upper Arms (w/ covers)

Our updated design features a billet aluminum cover for the uniball, providing protection against dirt and contaminants. The cap is press-fit and sealed with an O-ring. Our Camburg upper arms replace the stock ball-joint with a larger 1.25 uni-ball bearing, increasing wheel travel and durability. We also improve caster and camber curves for better alignment and handling. Our arms are designed using CAD/CAM 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 and include all necessary hardware. They are designed for 1-3″ of lift and fit 6 lug model trucks.

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.

New for 2020, our Camburg upper arms feature a billet aluminum cover for the uniball, protecting it from dirt and contaminants. The stock upper arms limit suspension performance when lifting your truck, but our arms address this issue. We replace the stock ball-joint with a larger 1.25 uni-ball bearing, increasing wheel travel and durability. The arms are made with thicker 1.50″ x.188″ wall tubing for strength and do not require removal of the factory droop stop/perch. Our arms are designed using CAD/CAM software and manufactured in-house with precision welding and CNC machining. They correct camber and caster, improve driving characteristics, and come with polyurethane frame pivot bushings and FK 1.25″ PTFE-lined uniballs. The arms are powder-coated and include all necessary hardware. They are designed for 1-3″ of lift and should not be used with longer shocks or lift kits without confirmation from our sales department.
