B&W Hitches 2-5/16" Ball Diameter Forged Steel B&W Hitches HB94001 -- 2-5/16" x 1" Shank x 2-1/2" Trailer Hitch Ball

When you're hauling a heavy trailer, a fifth wheel, or a gooseneck setup, the hitch ball is the single point where everything connects. The B&W Hitches HB94001 is a forged steel 2-5/16 inch hitch ball built to handle serious towing loads without flexing, cracking, or corroding prematurely. If you need a reliable, properly sized replacement ball for a standard coupler-equipped trailer or a gooseneck adapter application, this is a straightforward, quality-made choice from one of the most trusted names in the towing industry.

Heavy-Duty Towing Starts with the Right Ball

B&W Hitches has built its reputation on precision-machined, forged steel towing components made in Humboldt, Kansas. The HB94001 is part of their standard replacement and accessory ball lineup, designed to fit the most common heavy-duty towing ball mounts, adjustable ball mounts, and gooseneck coupler adapters that accept a 2-5/16 inch ball.

The 2-5/16 inch diameter is the largest standard trailer ball size used in North America and is required for high-capacity couplers rated at 12,500 lbs or more gross trailer weight. If your coupler is stamped "2-5/16" -- which is standard on most large travel trailers, toy haulers, car haulers, livestock trailers, and heavy equipment trailers -- this is the correct ball size.

The 1 inch round shank diameter and 2-1/2 inch shank length are the key fitment dimensions. Always verify your ball mount's shank hole diameter and the minimum thread engagement requirements for your locking nut before installing.

Forged Steel Construction

Forged -- not cast -- steel for superior grain structure, impact resistance, and long-term durability under high towing loads.

2-5/16" Ball Diameter

Matches the largest standard North American coupler size, required for couplers rated 12,500 lbs GTW and above on most large trailers.

1" Round Shank

Standard 1 inch round shank fits most heavy-duty ball mounts, gooseneck adapters, and adjustable receiver ball mounts with a 1 inch hole.

B&W Quality Standard

Made by B&W Hitches, a US-based manufacturer known for precision towing products including the Turnoverball and Companion 5th wheel systems.

What the Dimensions Mean for Your Application

Getting the right hitch ball requires matching three measurements to your setup: ball diameter, shank diameter, and shank length. Here is how the HB94001 fits those requirements:

  • Ball Diameter -- 2-5/16": Must match your coupler's rated ball size exactly. A coupler stamped 2-5/16" will not seat correctly on a 2" or 1-7/8" ball.
  • Shank Diameter -- 1": The shank must fit through the ball mount hole without play. A 1 inch shank requires a 1 inch hole in the ball mount.
  • Shank Length -- 2-1/2": Must provide sufficient thread engagement below the ball mount for the locking nut. Most ball mount manufacturers require a minimum of 1 inch of thread engagement; verify before installing.
Common Applications for a 2-5/16" Ball
  • Large travel trailers and 5th wheel gooseneck adapter hitches
  • Toy haulers and car haulers with heavy-duty couplers
  • Livestock trailers and horse trailers
  • Equipment trailers rated 10,000 lbs and above
  • Boat trailers with 2-5/16" couplers (larger cabin cruisers, pontoons)
  • B&W Turnoverball gooseneck systems using a ball mount adapter with a 2-5/16" coupler

B&W Hitches Product Family Context

B&W Hitches produces several hitch ball variants across different shank diameters and ball sizes. The HB94001 specifically covers the 2-5/16 inch ball with a 1 inch shank at 2-1/2 inches long -- the most commonly specified combination for heavy-duty adjustable ball mounts and aftermarket gooseneck coupler adapters. If your ball mount requires a different shank diameter (such as 1-1/4 inch) or a different shank length, verify before ordering, as B&W offers other part numbers to cover those configurations.

Coupler Compatibility Note

The 2-5/16 inch ball size is standardized across the industry. This ball will function with any brand of 2-5/16 inch rated coupler -- Bulldog, Reese, Curt, Fulton, Atwood, and others -- as long as the coupler is in good working condition and properly adjusted for ball diameter. The ball itself does not limit towing capacity; your tow vehicle's rated capacity and the ball mount's rated capacity determine the safe towing limit for the complete assembly.

Check Your Ball Mount Rating

The hitch ball is one component of a complete towing assembly. Always confirm that your ball mount, receiver hitch, and tow vehicle are all rated for the gross trailer weight you intend to tow. Using a correctly sized ball does not override a lower-rated component elsewhere in the system.

Installation and Maintenance Tips
  • Torque the locking nut to the specification on your ball mount or the ball manufacturer's recommendation -- typically 150 to 250 ft-lbs for a 1 inch shank ball, depending on thread pitch.
  • Apply a light coat of grease or anti-seize to the shank threads before installation to prevent galling and make future removal easier.
  • Inspect the ball surface periodically for flat spots, pitting, or corrosion. A worn ball surface can cause coupler slippage under load.
  • Re-torque the locking nut after the first 50 miles of towing and periodically thereafter.
  • Store the ball with a coupler cover or ball cover when not in use to reduce oxidation on the ball surface.

Important Information -- Read Before Purchasing and Installing
  • Always match ball diameter exactly to your coupler's rated ball size. A 2-5/16" coupler must use a 2-5/16" ball -- no substitutions.
  • Verify your ball mount has a 1 inch diameter shank hole before ordering. Using a shank that does not fit the hole precisely is a safety hazard.
  • The 2-1/2 inch shank length must provide adequate thread engagement below your ball mount for the locking nut. Inadequate thread engagement can cause the ball to loosen under load.
  • This ball does not include a ball mount, receiver hitch, or coupler. Ensure all components in the towing assembly are rated for your intended gross trailer weight.
  • Do not exceed the towing capacity ratings of any component in the system -- tow vehicle, receiver hitch, ball mount, hitch ball, and coupler must all be rated appropriately.
  • Inspect the hitch ball before each tow for signs of wear, cracks, or corrosion. Replace immediately if damage is found.
