Pull serious weight without sacrificing your truck bed. The B&W Turnoverball GNRK1121 installs completely underneath the bed floor, leaving a clean, flat surface when the ball is flipped down or removed entirely. When you need to tow a gooseneck trailer -- livestock, flatbed, equipment, or fifth-wheel with a gooseneck adapter -- flip the ball up, lock it in, and go. No bulky above-bed rails, no permanent hardware cluttering your hauling space.
B&W Hitches has built the Turnoverball line around a single idea: your truck bed should look like a truck bed, not a towing platform. The GNRK1121 is a complete under-bed gooseneck hitch kit that includes the hitch receiver frame, the pivoting ball assembly, and the vehicle-specific mounting hardware needed for a solid, no-drill-through-the-bed installation on compatible trucks.
The 2-5/16 inch gooseneck ball flips down flush with the bed floor when not in use, covered by a trim plug that blends into the bed surface. When you're ready to tow, remove the plug, flip the ball up, and lock it in place with the ergonomic hand-operated handle -- no tools required at the ball itself. The entire ball assembly can also be fully removed and stored, leaving only a covered hole in the bed.
Ball pivots below bed level when not towing. Flip up and lock in seconds -- no tools needed at the ball. Bed plug included for a clean look when stowed.
Engineered for heavy-duty gooseneck use. Rated for up to 30,000 lb gross trailer weight and 7,500 lb tongue weight on qualifying trucks.
Ships as a full installation kit -- under-bed frame, ball assembly, mounting brackets, and all required hardware. Truck-specific fit for proper load transfer.
Built in Humboldt, Kansas. B&W uses domestic steel and in-house manufacturing for consistent weld quality and dimensional accuracy on every hitch.
The Turnoverball is B&W's flagship under-bed gooseneck hitch line and has been the benchmark for clean gooseneck installations for decades. Unlike above-bed gooseneck systems that use a fixed ball and visible frame rails across the bed, the Turnoverball routes all structural load directly through purpose-built under-bed mounting points -- typically the frame rails and cross members of the truck -- for maximum strength with zero above-bed obstruction.
GNRK1121 is a truck-specific kit in the Turnoverball lineup. The "GN" prefix denotes a gooseneck configuration, and the kit number (RK1121) identifies the specific vehicle application and hardware package. Always confirm your truck's year, make, model, cab, and bed length against B&W's fit guide before ordering, as different kit numbers serve different truck configurations even within the same model year.
The GNRK1121 is designed for a clean, professional installation that does not require cutting holes in the truck frame or welding. The kit uses the truck's existing frame and bed mounting locations. General installation steps include:
Bed removal is the most labor-intensive part of the job. With a helper and basic hand tools, most experienced DIYers complete the installation in 3-5 hours. Professional installation is available at B&W-authorized dealers.
