Stop swapping balls every time you change trailers. The B&W TS10037B gives you both common hitch ball sizes -- 2-5/16 inch and 2 inch -- on a single forged steel mount that flips in seconds. Whether you're hooking up a fifth-wheel-ready gooseneck adapter, a conventional travel trailer, a boat trailer, or a utility hauler, one mount handles it all. Built in the USA to B&W's heavy-duty Turnoverball standards, this Class IV unit is engineered for trucks and serious towing, not weekend-only duty.
The TS10037B is part of B&W's Turnoverball double ball mount lineup -- a series purpose-built for truck owners who tow more than one type of trailer. The mount slides into a standard 2-inch receiver hitch and locks with a standard hitch pin (not included). Flip the shank 180 degrees and you switch between the 2-5/16 inch ball (for most conventional travel trailers and heavy-duty trailers) and the 2 inch ball (for utility, boat, and lighter-duty trailers), no tools required beyond a mallet or your hands depending on fit.
Forged steel construction -- the same approach B&W uses across their Turnoverball gooseneck and fifth-wheel product lines -- means this is not a stamped or welded assembly. The one-piece forged shank and ball platform handles real-world shock loads without the flex points that welded mounts develop over time. This is a Class IV rated mount, appropriate for the higher tongue weight capacities found in heavy half-ton and three-quarter-ton truck applications.
Ships with both a 2-5/16 inch and a 2 inch hitch ball already installed. No need to source balls separately or carry spares in your truck bed.
One-piece forged steel shank -- not stamped, not welded -- for maximum strength and long service life even under repeated heavy towing cycles.
Designed for Class IV hitch applications common on half-ton and three-quarter-ton trucks with 2-inch receiver tubes and high gross trailer weight ratings.
Flip the mount to change active ball size without removing the shank from the receiver. Quick enough to do at the trailer park or boat launch.
B&W offers double ball mounts in several drop/rise configurations and finish options. The TS10037B is the Class IV model pairing a 2-5/16 inch ball with a 2 inch ball -- the two most common ball sizes in North American RV and trailer towing. This covers the vast majority of applications a truck owner encounters:
If your application requires a 1-7/8 inch ball, or if you need a specific drop/rise that differs from this model, check the broader B&W double ball mount series for the matching configuration. The TS10037B is designed for a level or near-level towing setup on most full-size trucks with standard 2-inch receiver heights.
The TS10037B fits any standard 2-inch receiver hitch tube rated Class III or Class IV. Common fitments include:
Verify your hitch receiver's gross tongue weight (GTW) and tongue weight (TW) ratings against your trailer's actual tongue weight before towing. The mount itself is Class IV rated, but your hitch, frame, and truck ratings are the binding limits.
This mount is well-matched to the mixed-use towing that RV owners and outdoor enthusiasts actually do. Consider these common scenarios:
