B&W Turnoverball Kit

The B&W Turnoverball is an underbed gooseneck trailer hitch for Chevrolet / GMC that gives you a rock-solid 30,000-lb towing connection when you need it and a completely flat, open truck bed when you don't. The 2-5/16" hitch ball drops into a below-the-bed socket for towing, then flips upside down and stores out of the way in seconds — no removable balls to lose and nothing left sticking up in your bed. It's an ideal upgrade for ranchers, contractors, RVers, and everyday drivers who tow a gooseneck or fifth-wheel trailer but still want full use of their truck the rest of the week. With a custom bolt-on installation kit, made-in-USA construction, and a limited lifetime warranty, it's a true performance upgrade and one of the most trusted gooseneck towing solutions on the market.

• 30,000 lb towing capacity – A 30,000-lb gross trailer weight and 7,500-lb tongue weight rating give you the muscle to haul heavy goosenecks, livestock, and equipment with confidence
• Flip-over hitch ball for full bed access – Pull the handle, flip the 2-5/16" ball upside down, and drop it back in to reclaim a flat, usable truck bed in seconds
• Secure 5/8" locking pin – A spring-loaded steel pin slides all the way through the ball base for a tight, dependable lock every time you tow
• No-weld custom installation – The included mounting kit bolts to existing holes in your frame, so there's no welding or bed removal required

This hitch is built around a single-piece, machined ball socket that creates a strong, precise connection and won't flex or shift under heavy strain. The square ball base is a B&W signature — it keeps the ball from spinning in the socket during hookup so the trailer lines up easily, and when the ball is stored, its corners-only fit lets dirt and grime fall through instead of packing in. The gray powder-coated steel construction resists corrosion and UV fade, holding up to years of hard, year-round use.

Because the whole system mounts below the bed, your truck looks factory-clean when you're not towing. Built-in, spring-loaded safety-chain hookups are part of the design, and the Turnoverball platform accepts a range of B&W accessories — offset and raised balls for extra clearance, a 4" extender, or the B&W Companion fifth-wheel adapter that drops straight into the socket with no extra parts.

This is a custom, vehicle-specific application designed to bolt to the factory mounting points on the trucks listed below.

Installation is a straightforward bolt-on job. The custom brackets attach to existing holes in your truck's frame — no welding and no bed removal required. You will need to cut one 4"-diameter hole in the bed for the hitch ball and drill smaller holes for the built-in safety-chain loops. The operating handle is positioned at the rear driver's-side wheel well so you can lock or release the ball without climbing into the bed. Most installers complete the job with basic hand tools and a drill; we recommend reviewing the included B&W instructions for your specific truck before you begin.

• Built-in spring-loaded safety-chain hookups

Keep the hitch working smoothly by applying white lithium grease to the corners of the square ball post as needed — how often depends on how much you tow and how dirty your environment is. If the grease coating looks gone, it's time to reapply. Wipe out the socket if debris collects, keep the moving handle and pin clean, and store the ball flipped down in the socket when it's not in use to keep it protected. An occasional rinse and inspection of the locking pin will keep everything operating reliably for years.

The B&W Turnoverball is backed by a limited lifetime warranty covering defects in materials and workmanship. Normal wear, cosmetic finish wear, and damage from misuse, overloading beyond rated capacity, or improper installation are not covered. No separate registration is required to be covered, but keep your proof of purchase. For full terms, refer to the manufacturer's warranty documentation.

• Gooseneck hitch: A heavy-duty hitch that connects in the bed of a truck (rather than at the bumper), using a ball that couples to a trailer's overhead gooseneck arm for greater capacity and stability.
• Gross trailer weight (GTW): The total weight of the trailer plus everything loaded on it — here, up to 30,000 lbs.
• Tongue / vertical load weight: The downward weight the trailer places on the hitch ball — rated to 7,500 lbs on this hitch.
• 2-5/16" ball: The diameter of the coupling ball; 2-5/16" is the standard size for heavy gooseneck trailers.
• Powder-coated steel: Steel finished with a baked-on protective coating that resists rust, chipping, and UV fade better than ordinary paint.
• Companion adapter: A B&W fifth-wheel hitch that mounts directly into the Turnoverball socket, letting the same hitch tow a fifth-wheel trailer.
