Cognito Uniball SM Series Upper Control Arm Kit for 19-20 Sierra 1500/1500 AT4 and Silverado 1500/1500 Trail Boss 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. FK 1.25 Inch Uniball 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 Uniball angle for lifted and leveled applications. The allowable droop travel is also improved with the design of these arms. Made in the USA.
