Cognito Ball Joint SM Series Boxed Style Upper Control Arm (UCA) Kit 20-25 6.6L GM Duramax AFE-50-74003 Wire harness and switch soldUpon leveling or lifting your Duramax, its imperative to upgrade your upper control arms in order to correct the ball joint angle to increase ball joint and bushing life. While some opt to utilize uniball style UCA's, these require frequent maintenance and lubrication, where a heavy duty ball joint is typically more desirable for a daily driver. Upgrade your GM with this kit from Cognito.
