Stop swapping ball mounts every time you switch trailers. The B&W TS10037BB gives you both a 2-inch and a 2-5/16-inch ball on a single solid-steel mount, so you can flip it to match whatever you're hooking up -- from a lighter utility trailer to a full-size travel trailer or fifth-wheel-ready gooseneck setup. Built to B&W's exacting tolerances in Humboldt, Kansas, this is the kind of hardware that outlasts the truck it rides under.
The TS10037BB is part of B&W's Turnoverball system -- a line of premium receiver and gooseneck hitch accessories built around the idea that tow vehicle owners shouldn't have to own a drawer full of ball mounts. This double-ball version carries a 2-inch ball on one side and a 2-5/16-inch ball on the other, making it instantly compatible with the two most common trailer coupler sizes on the road.
The mount is machined and welded from solid steel, then finished with a durable black powder coat that resists road grime, UV exposure, and the kind of abuse that comes with regular trailering. At just under 30 pounds, this is a substantial piece of hardware -- the weight reflects the steel density, not wasted bulk.
2-inch and 2-5/16-inch balls on a single reversible mount -- covers the majority of travel trailers, boat trailers, horse trailers, and utility haulers without any swaps.
Engineered for heavy-duty towing applications. Class IV receiver compatibility means this mount is suited to 3/4-ton and 1-ton trucks with substantial tow ratings.
B&W builds in Humboldt, Kansas using domestic-quality steel. No cast zinc, no hollow shanks -- the same solid-steel philosophy applied across the entire Turnoverball lineup.
Designed to pair with B&W's Turnoverball gooseneck hitch platform, giving fifth-wheel and gooseneck owners a unified, premium towing ecosystem.
RV owners who regularly switch between trailers will get the most out of the TS10037BB. If your household runs a travel trailer with a 2-5/16-inch coupler and a smaller utility or car trailer with a 2-inch coupler, this single mount handles both without a toolbox dig. It's also a smart choice for full-timers or seasonal campers who tow a dinghy or boat trailer in addition to their main rig.
The 2-5/16-inch ball is the standard size for most Class III and Class IV travel trailers, including the majority of rigs from Forest River, Keystone, Heartland, Grand Design, and similar brands. The 2-inch ball picks up boat trailers, motorcycle trailers, smaller utility hauls, and older conventional couplers.
The TS10037BB is designed for 2-inch square receiver tubes, which are standard on Class III and Class IV hitches found on most 1/2-ton, 3/4-ton, and 1-ton pickup trucks and SUVs. The mount uses a standard hitch pin and clip retention (hitch pin not included -- use a 5/8-inch pin or a locking hitch pin for security).
Verify drop or rise measurement before ordering. B&W manufactures multiple shank drop configurations across the Turnoverball double-ball lineup. The TS10037BB shank is sized for typical truck frame heights -- measure from the top of your receiver tube opening to the desired ball height to confirm this model is the correct drop/rise for your application.
The black powder coat finish on the TS10037BB provides solid protection against surface rust and UV degradation. For extended life, especially in salt-belt states or coastal regions, periodic application of a rust-inhibiting spray on the shank and exposed metal surfaces is recommended after washing.
