The X-Mount Trailer Hitch Ball Mount is a receiver hitch accessory consisting of a trailer ball platform and shank. The unique, patented X-Mount shank design allows less surface contact and channels away moisture to minimize rust build-up and seizing within the aperture of the receiver hitch. The ball mount also features a lockrail system that functions as a built-in wrench. It allows you to torque the hitch ball with a single wrench by preventing hitch ball rotation during installation or removal from the ball mount. The X-Mount ball mount can be used in either the drop or rise position for towing applications depending on your requirement.
