GM Heavy Duty trucks are known for their inherent steering problems, and Cognito is known for providing the industry leading solution to these flaws with our Pitman and Idler Arm Support Kit. Now, we are proud to offer the Cognito Steering Stabilzer kit for 2011-2026 GM Heavy Duty trucks, providing a simple bolt-on solution with a premium steering stabilizer. Paired with our Pitman and Idler Arm Support Kit, the Cognito 2.0 IFP Steering Stabilizer provides top of the line steering feel and performance for the toughest applications. The Cognito Steering Stabilizer kit is bolt-on compatible with zero modification with both the Cognito Pitman and Idler Arm Support Kit and the Cognito Extreme Duty Center Link kit. 2011-2014 and certain 2015 model year trucks will require the OEM steering stabilizer mount tabs to be cut off. For 2016+ models, this kit is a simple and complete bolt on -- no cutting, no drilling, no welding.
