OVERVIEW This 4-Link System not only gives your truck an 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. This harder surface minimizes deflection to increase the over all handling characteristics of the truck. The lower links in the system include ICON’s patented pinch bolt housing which allows for on truck adjustability. TECH INFO: Requires ICON 4-Link brackets, part # 164500, 164503, or 164504 and ICON upper links part # 164502 for complete installation.
