Here is the most used tire carrier hinge kit on the market. These units are rated at 1,000 lbs.! The spindles fit into a 1.25" hole in your bumper and include all bearings, races, seals, and hardware needed for installation. Once you weld the spindle into your bumper and weld the 2.25" OD hinge tube onto your tire carrier you have a well sealed and very strong assembly. These can also be used for any fabrication project you have that needs a heavy duty pivot--there are thousands of creative ways to utilize these units.
