CURT specialty ball mounts are a group of exceptional towing products, built to succeed where others fear to tread. From the back roads of overrun forests to the muddy fields of small town farms, towing looks a little different, and that means different demands on your towing equipment. CURT offers a full lineup of unique ball mounts that are made to tackle the rougher side of towing while still being able to fit a standard 2 Inch X 2 Inch receiver tube. This sway control ball mount is perfect for adding a sway control unit to your vehicle trailer combination without using a weight distribution hitch. It features a standard ball mount design for towing a trailer but also features a welded sway control tab to attach the CURT sway control unit #17200. While the trailer ball platform is equipped with a 1 Inch hole to accept a standard trailer ball, the sway control tab offers a 5/8 Inch diameter to mount the CURT sway control ball #40093. This specialty ball mount has a gross trailer weight capacity of 7,500 Pound and a tongue weight capacity of 750 Pound, making it an excellent choice for larger trailers that may require sway control. For long lasting reliability, it comes finished in our gloss black powder coating to provide the corrosion, scratch and UV resistance needed to survive anything you throw its way.
