With so many different trailer ball and ball mount sizes available, it is a possibility for a trailer ball and ball mount to be mismatched. Though we pride ourselves on offering a complete selection of towing equipment and design our products to be an exact fit for your towing application, we understand that making a minor adjustment to your towing equipment is much more cost-effective than purchasing brand new equipment. 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 does not matter how much torque you apply to the trailer ball nut; if you have a trailer ball shank that is too small, it will eventually come loose in the ball mount platform and lead to trailer sway and even a breakaway. A CURT reducer bushing provides an effective filler for any gap that might surround your trailer ball shank. CURT reducer bushings come in three sizes to fit most standard trailer ball and ball mount sizes. This particular reducer bushing is designed to reduce a 1" hole down to 3/4". All CURT reducer bushings come with a yellow zinc finish to prevent rust and corrosion.

Fits:

Universal fit (not vehicle-specific). Compare the dimensions and ratings to your vehicle and trailer before ordering. Never exceed the lowest-rated towing component.
