CMB X-Joint Upper Arms

Our 21'-' F-150 KINETIK Series billet upper control arms allow for increased wheel travel and articulation out on the trail, corrected suspension geometry with increased caster for improved handling both on and off-road and are considerably higher quality and higher strength compared to the OEM parts for off-road use. These arms have undergone extensive CAD designing and machining to meet our high standards. They are CNC machined in-house from aerospace quality 6061 billet aluminum, Type II anodized and laser etched. They utilize 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. Additional camber and caster adjustment is available with the use of larger and stronger FK 7/8" chromoly heim joints, which also eliminate flexing/deflection under hard use and heavy braking without binding. Step by step instructions with all the necessary hardware ensure successful installation for your next off-road adventure. KINETIK Series X-Joint XL Upper Control Arm Kit.
