Product Description

The Cognito 110-91252 is a direct stock-replacement upper control arm built specifically for the 2024 Silverado 2500HD ZR2 and Sierra 2500HD AT4X, addressing the unique geometry of these off-road trims rather than a generic HD application. The corrected ball joint angle and added caster improve steering feel and stability while keeping the factory ride height and droop travel intact.

Boxed sheet metal construction with a semi-gloss black powder coat finish gives the arms long-term durability, while maintenance-free ball joints and pivot bushings cut down on upkeep over the life of the part. With roughly a 2-hour install time, it's a clean way to upgrade away from the factory arms on these trims without changing the truck's stock ride height or geometry.
