Chevrolet Silverado 1500 Trail Boss Upper Control Arm Kit - Front - Cognito - Billet, Delta Joint, Adjustable (2019-2026). This billet UCA kit corrects front-end geometry and adds precise camber/caster adjustment for confident on- and off-road handling.

CNC machined from 6061 billet aluminum, it replaces the OE ball joint with the ICON Delta Joint for high-angle, bind-free travel at full bump and droop. PTFE-lined 7/8 inch FK rod ends deliver precise function through the entire range of motion. A vehicle-specific taper pin provides OE-like fitment, and the O-ring sealed dust cap helps protect the Delta Joint. Includes all components and hardware. Tech notes: compatible with 0–1.5 inches of front lift on Trail Boss; coil-spring front only; not compatible with Silverado ZR2 or Sierra AT4X; Adaptive Ride Control models require aftermarket front/rear shocks plus parts 71021 and 71022.
