Cognito ball joint style boxed sheet metal upper control arm kit for Chevrolet and GMC 2014-2018 1500 2WD / 4WD trucks & SUVs. ONLY compatible with vehicles that were factory equipped with stamped steel or aluminum control arms. Made in the USA specifically for leveled and lifted applications where an upgrade is desired to provide better performance, style, and function. The boxed sheet metal arms are CNC robot welded and powder coated semi gloss black. Cognito alloy series 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. This control arm kit will add performance to the Chevy and GMC truck by correcting the ball joint angle for lifted and leveled applications. The allowable droop travel is also improved with the design of these arms.
