The precision machined greaseable Delrin bushing Thuren Fabrication uses as the shackle pivot, provides smooth bind-free shackle swing. When performance suspension is added to the truck, the extension and compression of the leaf springs length, can bind up the tight rubber OEM shackle bushing. This adds unwanted restriction forces, and removing every bit counts. This shackle was originally designed as the key component to Thuren Fabrication Extreme Travel extended Leafs, but will fit any truck with OEM or aftermarket leafs. As an added benefit, Thuren Fabrication added the ability to tune the rear suspension height with multiple mounting positions. The closest hole is stock height, the middle hole provides about 3|4 inch of lift, and the end hole provides about 1.75" of lift
