CURT Switch Ball Trailer Ball Set offers the ultimate in convenience and reliability for a variety of light-duty and medium-duty towing applications. With its exclusive J-groove design, the Switch Ball trailer ball allows different heads or ball sizes to be placed on the shank for accommodating different coupler sizes. This means there is no need to switch between ball mounts or even to own a second ball mount to fit an additional trailer. When you need to make the switch, simply twist the Switch Ball head, lift it off and twist on another. The J-groove ensures a solid hold on your trailer, while still allowing for easy removal of the trailer ball without tools or pins.
