Cognito Ball Joint SM Series Upper Control Arm Kit for 2020-2021 Chevrolet and GMC 2500HD / 3500HD 2WD/4WD trucks. Fits as stock replacement or 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. Alloy series ball joints are included as well as new crush sleeves and polyurethane bushings. Upper control arms are not meant to be a droop limiter, in the old days they were the limiter but wreaked havoc on upper ball joints.
The shocks or a limit strap should be the droop limiter, and 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, increasing droop travel, and also increases caster slightly for better highway speed drivability.

The upper control arm is not designed to be the droop travel “limiter” in which case it could cause excessive wear and strain on the upper ball joint. Therefore, the correct length shock must be used so that it can act as the droop limiter.
Only designated shocks that meet Cognito specifications must be used in conjunction with these upper control arms. Installation of non-designated shocks with these upper control arms will void the Cognito warranty, and may damage the control arms, ball joints, tie-rods, cv axles and other components.
