Our Bumper Mounted Spare Tire Carrier was designed exclusively for use with our RBJK-13 MTO Rear Bumper. The carrier swings out with the tailgate to provide ample access to the cargo area. A dual taper bearing and dual heim hinge pivot provides for easy and smooth operation of the carrier. By moving your spare tire off of the tailgate you protect it from flexing and movement when driving off-road.
