The Cognito SM Series Upper Control Arms are designed specifically for lifted and leveled GM HD trucks. They correct ball joint angles, increase usable droop travel, and add a slight increase in caster for improved highway stability and drivability. The result is better suspension performance on-road and off-road, with reduced stress on critical components.

Constructed from fully welded, boxed sheet metal and finished in a durable semi-gloss black powder coat, these control arms come fully assembled with maintenance-free heavy-duty ball joints and pivot bushings for a true bolt-on installation.

Cognito forged torsion bar keys level the front of the truck to match the rear while maintaining strength and reliability. Their forged construction makes them exceptionally durable, and they install easily using factory mounting locations.

Paired with the suspension components are FOX 2.0 Performance Series IFP smooth-body shocks, featuring race-proven damping technology. The internal floating piston (IFP) design prevents oil aeration, ensuring consistent performance, a comfortable on-road ride, and predictable off-road control in demanding conditions.
