If you're looking to build your own swing away tire rack, then you can try our tire rack hitch kit. The kit includes a standard 1.25-inch spindle and all the bearings, races, seals, and hardware needed for installation. By first inserting the spindle into the hole you drilled in the bumper and then welding the hinge tube to the tire carrier, you have completed a well-sealed and very strong assembly. These kits can also be used for any fabrication project that requires a heavy duty pivot - there are hundreds of creative ways to utilize these kits.
