ICON's Billet Aluminum Rear Trailing Arms for the Toyota FJ Cruiser, 4Runner, 200 Series Land Cruiser, and Lexus GX are a great replacement for weak factory lower links. These trailing arms are light, strong, and have been engineered to increase the off - road ride quality the vehicle. Constructed out of 6061 CNC - machined billet aluminum, these arms also stand out when bolted up on the vehicle. They include 16T Rod Rod Ends that have a load rating of over 40,000 lbs of pressure as well as a dual rate bushing on the axle side for excellent articulation characteristics with minimal deflection. A replaceable nylon rock slider is incorporated into the design of the arm to prevent any hang - ups on the trail.
