When lifting your 19'-25' Silverado 1500, 19'-25' Sierra 1500, 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 replace the stock ball-joint with our Camburg X-Joint for increased strength, longevity and high misalignment, allowing for maximum wheel travel. The X-Joint is a high performance, all-weather, all conditions, high angle ball joint. These fully sealed and greaseable joints are perfect for extreme conditions, so dirt, sand, rain, mud and snow are no match for them. The tubular construction also gives you more tire & shock clearance compared to the weaker stock stamped sheet metal arms. 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. Step by step instructions, with all the necessary hardware, ensure a successful installation for your next off-road adventure.
