The UCF Aluminum Rear Bumper & Tire Carrier for Jeep JK is a great option for those that want more protection than some other companies offer. This bumper is the full width of the Jeep and actually protrudes from the sides be a couple inches to protect your sheet metal. It extends forward to the rear of the back fender wells. The combined weight of the bumper and tire carrier is less than 100 lbs.
We were able to keep the weight to a minimum with intelligent material selections. The frame mounting system is made from 1/4" & 3/8" carbon steel plate. The d-ring mounts are 3/4" thick and welded to the 3/8" mounting plates. The bumper body is made from 3/16" 6061-T6 aluminum hard plate. We used large radius tooling to make all the bends on the bumper body for added strength and style. Any manufacturer using 6061-T6 aluminum must use large radius tooling to avoid material fracture during the bending process. We have seen several companies that make this claim, yet they bend their parts with sharp tooling. This simply isn't possible.
The tire carrier is fabricated from 3/16" steel. It pivots on HD trailer bearings and is attached to the rear door with a double pivot. This allows the door/tire carrier to be opened with one hand in one smooth motion. When the tire carrier is closed it rests against the rear door via a rubber bushing that tensions the system sufficiently so that no rattles or vibrations are experienced.
The tire carrier is adaptable to many different available wheels, from stock 6" backspacing down to 3.5". It will handle tires as large as 37".
