Reducer BushingsCURT Reducer Bushing 21100

When you need a smaller size trailer ball for a smaller trailer but do not want to have to buy an entirely new ball mount, CURT reducer bushings are the simple, reliable solution. A reducer bushing is a zinc-plated steel ring that fits into the mounting hole of a ball mount to eliminate extra space when installing a trailer ball with a smaller shank diameter. This helps ensure the trailer ball nut stays firmly torqued and prevents rattling and sway. We have reducer bushings in a variety of sizes to fit trailer balls with shank diameters of 3/4”, 1” and 1 1/4”.
