CURT reducer bushings are the fast, easy way to make your trailer ball fit snugly into your ball mount for safe, quiet towing. Installing a trailer ball with any wiggle room between the shank and ball mount hole is a recipe for disaster. It doesn't matter how much torque you apply to the trailer ball nut; if you have a shank that is too small, it will eventually come loose in the ball-mount platform and lead to trailer sway or even a breakaway. These steel components provide an effective filler for any gap that might surround your trailer ball shank. Available in different sizes, all CURT trailer ball reducer bushings come with a yellow zinc finish to help prevent rust and corrosion.
