Pitman and Idler arms have been an inherent wear problem within the steering systems of Chevy and GMC vehicles for decades. When tie rod angles increase to anything above parallel to the center link, the life of pitman and idler arms decreases rapidly without this upgrade. The Cognito PISK (Pitman and Idler Arm Support Kit) prevents premature wear of pitman and idler arms by supporting and controlling the intended motion of these components in an innovative method which earned a Utility Patent. Say good bye to the need for a steering stabilizer which simply masks the root problem, this support kit is all that is needed to Fix the Flaw and control the GM pitman and idler arm style steering properly..
