@gadgetglimpse: This little wheel could save a Jeep's rear bumper. The Broken Rock Hitch Roller mounts into the rear hitch receiver. When the vehicle comes down a steep obstacle, the wheel can contact the ground and ROLL instead of letting the bumper drag across the rocks. It's basically a roller designed to take the hit. #OffRoading #JeepLife #OffRoadGear #RockCrawling #4x4
