The Cognito Ball Joint SM Series UCA Builders Kit fits the 2015-2019 GMC Sierra 3500HD and ships raw and un-assembled so builders can custom powder coat the arms before assembly.

Install Difficulty: Professional Install Only
Replaces factory upper control arms with hand tools and a ball joint press; typically takes 2-3 hours including assembly of the raw arms. Professional alignment required after installation.

Product Overview

This upper control arm kit replaces factory UCAs with a corrected ball joint angle for stock, leveled, or lifted Sierra 3500HD applications. The improved geometry also increases allowable droop travel, which protects ride quality and extends the life of related suspension components.

Arms ship raw so you can powder coat to your spec without pressing bushings and ball joints out of a pre-finished arm. Includes maintenance-free ball joints and pivot bushings.
