A 3-link Kit, usually consists of an upper "wishbone" shaped link and 2 lower links which are sometimes used in a "Bag-On-Bar" setup. These kits control the front to back motion, the rotation of the pinion, and the side-to-side movement as the rear differential articulates through its range of motion. Because of this, an additional link such as a panhard bar is not needed. Here you can find our selection of 3-Link Kits.
