For carrying the oversize tires that serious off-roaders require, the rear bumper is available in a version that is designed to accept the WARN Tire Carrier. Built to carry heavier tires (up to 37″), the tire carrier pivots on a beefy 1-1/2″ solid steel shaft pin, which comes up from within the bumper into the frame of the tire carrier. The shaft itself is welded, not bolted. Structural t-joint welds (vs. corner welds) mean the bumper holds up in the long run. A polyurethane pad reduces rattling. Bumper sold separately.
