Whether your truck is stock height or lifted and running oversized tires, Pitman and Idler arms have always been a problem on the steering systems of GM vehicles. PPE's Pitman and Idler arm Support kit fixes a wear problem that is present on the factory and aftermarket steering system. Some aftermarket companies have come out with heavier duty pitman and idler arms that fail the same way that the factory parts do. This design solves the problem in an innovative way. The problem when not using the Pitman and Idler Arm Support kit: If you are not familiar with how the GM steering system works, here is a quick lesson. The pitman arm is connected to the output shaft of the steering gear box. When you turn the steering wheel of your vehicle, the motion is directed to the steering gear box which then rotates the pitman arm. The pitman arm has a stud protruding from the end of it where the center link connects, also called the drag link. To help control steering motion, the center link is connected to an idler arm on the passenger side of the vehicle. The idler arm is bolted to the frame and swings in the same arc as the pitman arm, and is fastened to the center link the same way the pitman arm is. The two mounting points for the center link give it support in the motion left and right relative to the vehicle, but there is not enough support in the direction of forward to backward relative to the vehicle. This lack of support is what causes the joints inside of the pitman and idler arms to wear out, which provide the pivot and connection point for the center link. The larger the tire on the vehicle, the faster these joints wear out. Even with a beefed up aftermarket pitman and idler arms, the still can have the same premature wear issue in the same joint. What happens if you are not using this kit as a solution? The front alignment toe settings can not be held because of the slop in the pitman and idler arms allowing the center link to move forward and backward. No control over the toe setting means that your front tires will experience irregular and premature wear. When the center link swings toward the back of the truck, it is also swinging up in an arc. The center link swinging up increases the tie rod angle and can cause tie rod breakage. Most tie rod problems actual originate from pitman and idler arm problems.

The support kit can be installed on pitman and idler arms showing a lot of wear, and actually revive them! If the worn parts have approximately 40,000 miles or less on them with a close to stock size tire, they probably will not have to be changed. If the worn parts have approximately 20,000 miles or less on them with larger than 33in. tires, they probably will not have to be changed. If the parts have more miles than that on them, it is recommended to replace the pitman and idler arms with factory units and add the PPE Pitman and Idler Arm Support Kit.
