GMC Sierra 2500 Control Arm Kit - Cognito - SM Series UCA Builders Kit - `20-`24. A raw, unassembled upper control arm package for builders who want to powder coat and assemble their own setup without risking damage to pre-installed components.

Designed as a stock-replacement upgrade for 2020–2024 GMC Sierra 2500/3500 HD (2WD/4WD), this kit provides a corrected ball joint angle for leveled and lifted applications and improves allowable droop travel to support ride quality and component longevity. Maintenance-free ball joint and pivot bushings help minimize service, while added caster promotes confident tracking. Made in the USA by Cognito, it suits both refresh projects and custom suspension builds. Typical DIY install time is about 1.5 hours.
