9 I also added the ICON billet rear trailing arms that replace the very weak factory lower links known to bend and often break on rocks. Each arm uses 16T rod ends with a rating of over 40,000 pounds of pressure resistance before failure. They include a rebuildable Johnny Joint on the axle side for excellent articulation and minimal deflection. Using ICON’s pinch housing you can adjust them on the truck as well. The bottom side of each arm features a nylon rock slider for no-stick wheeling.
