This 4-Link System not only gives your truck a more aggressive look, it enhances the articulation of the front suspension and improves handling of the truck by eliminating the large radius arm bushing and replacing it with competition grade spherical bearings in each link. The spherical bearings have a harder surface which minimizes deflection to increase the over all handling characteristics of the truck. The lower links in this system include ICON's patented pinch bolt housing which allows for easier adjustment on the truck.
