2011-2019 Silverado/Sierra HD Ball Joint SM Series Upper Control Arm Kit (110-91071)

This UCA Kit Fits as stock replacement for leveled and lifted applications where an upgrade is desired to provide better performance, style, and function. The Cognito Alpha Joint SM Series Upper Control Arms add style, function, and performance to your vehicle by improving the allowable droop travel for a better ride quality. The control arm kit features boxed sheet metal arms that are CNC robot welded and powder coated semi-gloss black. These arms feature corrected ball joint angle for lifted and leveled applications. The allowable droop travel is also improved with the design of these arms. Ample droop travel is required for good ride quality and all suspension components to last and work properly.
