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" x 2" 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 comes with a welded sway control tab to attach the CURT sway control unit #17200. While the trailer ball platform is equipped with a 1" hole to accept a standard trailer ball, the sway control tab offers a 5/8" diameter to mount the CURT sway control ball #40093.This specialty ball mount has a gross trailer weight capacity of 7,500 lbs. and a tongue weight capacity of 750 lbs., 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.
