COG Idler Arm Support

Includes Fox Performance Series 2.0 IFP Steering Stabilizer This Cognito FOX Steering Stabilizer Kit is fully compatible with the Cognito Pitman and Idler Arm Support Kit. For 2016+ models, GM eliminated the factory clevis, making this kit a truly bolt-on solutionno cutting, drilling, or welding required. In 2011, GM introduced a redesigned HD platform with numerous improvements, including updates to the steering system and frame-mounted components. However, the pitman and idler arms remained mounted in single shear to the center linka known weak point. Most steering performance issues are addressed with the Cognito Pitman and Idler Arm Support Kit (SKU 110-90772), which reinforces the system by converting to a double shear mount. Still, some truck owners choose to further enhance control with the addition of a steering stabilizer. For model years 20112014 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 provisiona tapered hole near the idler arm. However, only 20112014 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.
