Camburg 17'-22' Colorado ZR2 Performance Series Upper Control Arm Kits

When lifting your vehicle, the stock upper arms become the limiting factor and hold back your suspension's performance. Our Camburg upper arms address these issues and more. We build more caster and change the camber curve to correct geometry, so the vehicle aligns correctly and improves driving characteristics and handling. We use stronger FK JMX Series chromoly heim joints to allow for additional camber and caster adjustment, and they eliminate flexing/deflection under hard off-road use and braking with zero binding. We replace the stock ball-joint with our new Camburg X-Joint XL for increased strength, longevity and high misalignment, allowing for maximum wheel travel. The larger X-Joint XL is an extreme performance, all-weather, all conditions, high angle ball joint. These are much higher quality, considerably stronger and have an improved boot design that allows for higher angle use, better greasing and increased longevity. With higher strength heat-treated chromoly materials and an improved design, we were able to vastly improve upon what was available on the market. These fully sealed and greaseable joints are perfect for extreme conditions, so dirt, sand, rain, mud and snow are no match for them. Manufactured in-house, we have the tubes CNC laser cut and bent, then are MIG welded in precision fixtures before sending out to be sandblasted and powder coated.
