Cognito 11-25 Chevrolet Silverado 2500/3500HD / 11-25 GMC Sierra 2500/3500HD Steering Idler Arm

For model years 2011–2014 and most of 2015, GM included OEM provisions for a steering stabilizer, requiring two mounting points: one on the right side of the steering center link and one on the left side of the frame. All 2011+ models retain the center link mounting provision—a tapered hole near the idler arm. However, only 2011–2014 and select 2015 trucks came with the frame-side mounting clevis (two welded tabs on the crossmember). This OEM clevis interferes with the Cognito bracket and must be removed if present, as the included FOX stabilizer is not compatible with the factory mounting location.

• 2011-2015 model years require cutting off of the OEM frame clevis with tabs
• Compatible with lift kits that have the center link in the factory location
• Simple and completely bolt on installation for 2016+ model years
• Compatible with the Cognito Pitman and Idler Arm Support Kit
• Reduce feedback from the road through the steering wheel
• DIY Install Time: 20 min

Improve steering control and reduce road feedback with the Cognito Steering Idler Arm, part number COG210-91333. Designed for 2011-2025 Chevrolet Silverado 2500HD and 3500HD and GMC Sierra 2500HD and 3500HD trucks, this steering component works with lift kits that retain the center link in the factory location. It is also compatible with the Cognito Pitman and Idler Arm Support Kit, making it a practical upgrade for heavy-duty steering systems.
For 2011-2014 trucks and most 2015 models, the factory steering stabilizer provisions include a frame-side mounting clevis with two welded tabs on the crossmember. This OEM clevis interferes with the Cognito bracket and must be removed when present. The included FOX stabilizer is not compatible with the factory mounting location. All 2011 and newer models retain the center link mounting provision, including the tapered hole near the idler arm, while model-year compatibility with the frame-side clevis may vary.
Installation is straightforward and designed for efficient garage service. Model-year 2016 and newer applications feature a simple, completely bolt-on installation, while 2011-2015 applications require removal of the OEM frame clevis with tabs. With an estimated DIY installation time of approximately 20 minutes, the Cognito COG210-91333 provides a durable steering upgrade for trucks using the factory center link position. Verify vehicle fitment and mounting configuration before installation.
