With the B&W Turnoverball underbed gooseneck trailer hitch you get the best of both worlds. When you go to tow, the Turnoverball creates a sturdy, dependable connection with your gooseneck trailer. And when you're done towing, you can stow the ball upside down in the hitch to get full bed access and a clean appearance.

Easy-to-Remove, Simple-to-Store Hitch Ball

The durable steel hitch ball included with the Turnoverball system secures in the hitch with a sturdy, 5/8" thick steel pin that is incorporated into the end of the operating handle. To lock the ball in place, drop it into the hitch hole in the bed of your truck. Then rotate the handle in your driver's-side wheel well counterclockwise until the latch engages. When the latch is engaged, the spring-loaded pin on the end of the handle will be inserted all the way through the base of the hitch ball, forming a strong, solid connection and ensuring absolute security when you're towing.

B&W Turnoverball Gooseneck Hitch Operation

When you're done towing, remove the hitch ball by simply pulling the handle out as far as it will go and then rotating it clockwise until it unlatches. Remove the ball, flip it upside down, and drop it back into the ball hole of the hitch. Then reengage the latch to secure the stowed ball in place.

Unlike typical gooseneck balls - which have round bases - the Turnoverball hitch ball is designed with a square base. This makes latching the ball in the hitch easier because the base won't rotate inside of the hitch like a round base might, so lining the pin up is a snap. The base of the ball also fits tightly within the ball hole during storage. Because only the corners of the base contact the sides of the socket, any dirt or grime that gets into the hitch will fall through the socket, thus helping to prevent any buildup that could cause the ball to seize up in the hitch.

Simple, Custom Installation

This hitch is custom designed for your vehicle. The included mounting brackets bolt to existing holes in your truck's frame. While some modification is required - you will need to cut a 4" diameter hole in your bed for the hitch ball and drill holes for the built-in safety chain loops - there is no need to weld onto or to drill into your frame.

Galvanic Corrosion Limiting Tape

Note: Because the body of your truck is constructed of aluminum, there is an increased risk of galvanic corrosion when a different metal, such as steel, contacts the truck body. To help prevent this corrosion, strips of polypropylene tape are included to provide a barrier between the steel of the hitch and the aluminum of the truck. These strips are to be applied to the center section of the gooseneck hitch as shown above.

Once you have the hitch brackets and body installed, set up the operating handle. This handle is designed to be accessed from the rear driver's-side wheel well. On the end of the handle is the heavy-duty steel pin that secures the hitch ball.

B&W Turnoverball Gooseneck Hitch Accessories

B&W makes it easy to tow just about anything. With the many adapters and accessories available, the Turnoverball can be made to work with almost any gooseneck trailer. Hitch balls are available that have a built-in rise, an offset, and even a different connection type. Add on the Companion fifth-wheel hitch - which attaches directly to the Turnoverball with no other parts required - and you can tow your fifth-wheel trailer. Even a truck bed utility rack is available so that you can easily haul ladders and lumber with the load placed on the hitch (and therefore your truck's frame) instead of your bed rails.

  • Hole Placement In Truck Bed to Install B&W Turnover Ball Gooseneck Hitch on 2021 Ford F-150
    I spoke with my B&W representative who confirms that to install their GNRK1121 # BW77FR Turnover Ball hitch on a 2021 Ford F-150, the center of the 4 inch hole for the gooseneck ball would be placed 42-5/8 inches forward of the rear edge of the truck bed (NOT the tailgate).
