The Cognito SM Series Builders Kit for 2011–2019 Silverado/Sierra 2500/3500 HD provides unassembled raw control arms for custom finishing and local assembly. Designed to improve ball joint angle and allow greater droop travel for leveled or lifted applications, the arms support better ride quality and component longevity while avoiding the risk of damaging pre-installed bushings during refinishing.
