The B&W GNRC825 is the center section mounting base used in B&W's legendary Turnoverball underbed gooseneck hitch system. Whether you are replacing a damaged center section, completing a previously started install, or upgrading a truck bed, this is the structural core that anchors the entire gooseneck assembly beneath your pickup bed -- keeping your cargo floor clean and flat when the ball is not in use.
B&W's Turnoverball gooseneck hitch is widely regarded as the gold standard in underbed gooseneck systems, and the center section is the heart of that design. The GNRC825 is the main structural receiver tube and cross-member assembly that mounts permanently beneath the truck bed. When the ball and bracket are removed, the bed surface remains level and unobstructed -- a major advantage over fixed-ball systems for everyday hauling.
This center section is machined and fabricated from high-strength steel with a durable powder coat finish. It accepts the B&W ball and shank assembly from above-deck through a purpose-cut hole in the bed, locking into position for towing and rotating out of the way when not needed. At 35.0 lbs and measuring 30.5 x 9.0 x 5.0 inches, this is a substantial, precision-built component -- not a lightweight afterthought.
Designed specifically for B&W Turnoverball underbed gooseneck hitch systems. The rotating ball-and-shank mechanism integrates directly with this center section.
When the ball is removed, the bed surface is fully flush and usable -- no permanent protrusion, no obstruction for hauling cargo, flatbeds, or equipment.
Fabricated from high-strength steel with a powder coat finish for corrosion resistance. Built to handle the demands of gooseneck trailer towing at rated capacities.
Engineered to B&W's exact specifications so the ball shank, safety chain loops, and mounting brackets all align correctly with truck-specific rail kits.
The B&W Turnoverball gooseneck system is a three-part assembly: the truck-specific mounting rails (sold separately by application), the center section (this unit, GNRC825), and the ball-and-shank assembly (sold separately). The center section bridges between the two mounting rails and houses the receiver socket into which the gooseneck ball shank drops and locks. Safety chain loops are integrated into the center section, providing a secure, clean anchor point below the bed surface.
Installation requires cutting a hole in the truck bed at the specified location -- typically centered over the rear axle -- and securing the rail-and-center-section assembly to the truck frame using the appropriate application-specific hardware kit. Once installed, the ball drops in from the top, locks with a twist, and is ready for towing. Removal takes seconds and leaves a small, capped hole -- virtually invisible in the bed floor.
The GNRC825 center section is the universal structural component used across a wide range of B&W Turnoverball application-specific kits. B&W builds truck-specific rail kits (identified by part numbers such as GNRK1013, GNRK1058, GNRK1065, and many others covering Ford, Chevy/GMC, Ram, and Toyota trucks) that mount to OEM frame locations without drilling. The GNRC825 center section mounts between those rails.
Gooseneck trailers use a ball-and-coupler system that mates to a 2-5/16 inch ball mounted in the center of the truck bed, typically over or slightly forward of the rear axle. This design is commonly used for livestock trailers, flatbed equipment trailers, and heavy-duty cargo trailers. The B&W Turnoverball system is rated for serious gooseneck loads -- making it the preferred choice for agricultural, commercial, and heavy recreational towing applications.
