These upper control arms are built with a modified ball joint angle to eliminate travel limitations of the ball joint in lifted applications.
This design also eliminates the need to cut the service perch off of the truck if they are used as part of our Cognito package or as a stock replacement. Upgrade your stock upper control arms with Cognito for better performance, style and function.
Bolt in, maintenance free, high angle, heavy duty ball joints are included as well as new crush sleeves and polyurethane bushings. Ample droop travel is required for good ride quality and all suspension components to last and work properly. The allowable droop travel is also improved with the design of these arms. Made in the USA.
Warning!-This product is not compatible with vehicles equipped with ARC Adaptive Ride Control (includes all 1500 Denali models). The Cognito Standard Upper Control Arm was not built with ARC compatibility and if installed will negate the ARC functionality of your 1500 Denali vehicle.
