When your B&W Turnoverball gooseneck hitch ball is worn, damaged, or corroded, you should not have to buy a whole new hitch. The GNXA2000 is the genuine OEM replacement ball designed specifically for B&W Turnoverball gooseneck hitch systems. Drop it in, torque it down, and get back to towing -- full capacity, factory fit, no adapters needed.
The B&W Turnoverball is one of the most popular under-bed gooseneck hitch systems in the truck market, known for its flush-mount design that disappears when not in use. Over years of heavy towing, the ball itself can wear or sustain impact damage. The GNXA2000 is B&W's direct replacement ball, machined and forged to the same specification as the original component your hitch shipped with.
This is not an aftermarket substitute -- it is the genuine B&W part, correct for Turnoverball applications that use the standard 2-5/16 inch ball diameter. At 9 pounds of forged steel and compact dimensions of 9.75 x 4.5 x 3.5 inches, this ball is built to the same heavy-duty standard as the rest of the Turnoverball system.
Factory-spec replacement from B&W Hitches -- the same manufacturer that built your Turnoverball hitch. No fitment guesswork.
Heavy forged steel at 9.0 lbs delivers the strength and wear resistance required for repeated gooseneck towing cycles.
Standard gooseneck ball size compatible with the vast majority of fifth-wheel-to-gooseneck adapters and gooseneck-equipped trailers.
Designed to install directly into existing Turnoverball hitch receivers -- no modification, no drilling, no new hardware kit required.
The B&W Turnoverball system is sold in truck-specific configurations for a wide range of full-size pickups from Ford, GM, Ram, Nissan, and Toyota. The GNXA2000 replacement ball is the shared ball component across the Turnoverball lineup. If your Turnoverball hitch originally came with a 2-5/16 inch ball (which covers the overwhelming majority of Turnoverball applications), the GNXA2000 is your correct replacement.
Common Turnoverball hitch models this ball services include units sold under part numbers in the GNRK and GNXA series. If you are unsure whether your specific hitch uses this ball, the ball diameter stamped or labeled on your existing ball is the easiest confirmation -- 2-5/16 inch means GNXA2000.
Gooseneck towing connects the trailer's coupler directly over the truck's rear axle using a ball-and-socket connection in the truck bed. This provides excellent weight distribution and a tight turning radius compared to bumper-pull setups. The 2-5/16 inch ball on the GNXA2000 is the industry-standard gooseneck diameter -- larger and stronger than the 1-7/8 or 2 inch balls used for bumper-pull trailers.
If you are towing a fifth-wheel trailer with a gooseneck adapter (such as a Reese or PW Industries fifth-wheel-to-gooseneck coupler), the 2-5/16 inch ball on the GNXA2000 is the correct interface point for those adapters as well.
Generic replacement gooseneck balls exist in the market, but they vary in shank diameter, thread pitch, and ball height -- any of which can cause a loose fit in a B&W Turnoverball receiver or place the ball at the wrong height for your trailer coupler. The GNXA2000 is manufactured by B&W to match the exact shank dimensions, thread spec, and ball height of the original component, so your coupler height and locking engagement remain exactly as designed.
