Sierra 2500HD/3500HD 2011-2026 GMC - Steering Stabilizer Kit Set by Cognito

The Cognito Steering Stabilizer Kit (110-91348) is designed to improve steering control and reduce feedback on 2011–up GMC Sierra 2500HD/3500HD trucks. GM HD trucks are well known for steering-related issues under heavy loads, larger tires, and lifted suspension systems. Cognito has long addressed these concerns with its Pitman and Idler Arm Support Kit, and this steering stabilizer kit complements that system with improved damping and steering feel.

At the heart of the kit is the Cognito 2.0 IFP Steering Stabilizer, engineered to reduce steering wheel kickback and road feedback while maintaining precise steering control. The Internal Floating Piston (IFP) design separates nitrogen gas from the shock oil to prevent aeration and maintain consistent damping performance in demanding driving conditions.

This kit is designed as a simple bolt-on upgrade and works seamlessly with the Cognito Pitman and Idler Arm Support Kit as well as the Cognito Extreme Duty Center Link Kit. It is also compatible with lift kits that retain the factory center link position.

For 2016+ models, installation is completely bolt-on with no drilling, welding, or cutting required. Some 2011–2015 trucks may require the factory steering stabilizer mount tabs to be removed during installation.
