Already running a gooseneck ball in your truck bed? The B&W GNRC912 center section is the core structural component of the B&W Companion fifth-wheel-to-gooseneck adapter system, letting you tow a standard fifth wheel trailer over a gooseneck ball without converting your entire hitch setup. If you are upgrading, replacing a worn center section, or completing a Companion system build, this is the part you need.
The B&W Companion system is one of the most respected fifth-wheel-to-gooseneck adapter solutions on the market, and the GNRC912 is the heart of that system. It mounts to your existing B&W gooseneck hitch infrastructure in the truck bed and provides the standard fifth wheel kingpin receiver jaw at the top, so your fifth wheel trailer couples exactly as it would with a traditional slider or fixed fifth wheel hitch head.
At 47.75 lbs and measuring 34.0 x 9.0 x 5.0 inches, this center section is machined and fabricated for heavy-duty towing duty. The design keeps the load centered over the rear axle and integrates directly with B&W's Turnoverball and compatible gooseneck ball platforms, giving you a clean, low-profile setup when the fifth wheel is not attached.
Designed as a direct component of the B&W Companion fifth-wheel-to-gooseneck adapter. Works with B&W Turnoverball gooseneck hitches already installed in your truck bed.
Accepts the standard 2-inch fifth wheel kingpin found on virtually all North American fifth wheel trailers. No special kingpin adapters or modifications required.
Heavy-gauge steel fabrication with a durable powder coat finish resists rust and road grime. Built to handle the repeated stress of long-haul towing and seasonal use.
Whether you are replacing a damaged center section or completing a new Companion system build, the GNRC912 drops in without custom fabrication or drilling.
The B&W Companion is a purpose-built adapter that bridges the gap between gooseneck-equipped trucks and fifth wheel trailers. Many truck owners -- especially those who also haul livestock, flatbed, or dump trailers -- prefer a clean gooseneck ball setup over a dedicated fifth wheel rail system. The Companion system lets you do both: run gooseneck trailers normally, then drop in the Companion head when you hook up your fifth wheel RV or cargo trailer.
The GNRC912 center section is the main receiver/jaw assembly that couples to the kingpin. It interfaces with the Companion's arm assemblies and mounting brackets, which attach to the gooseneck ball shank underneath. The system is designed to be installed and removed without tools in most configurations, so you are not committed to one trailer type.
The GNRC912 is a B&W Companion system component. It is compatible with B&W Turnoverball gooseneck hitches and the Companion arm/bracket assemblies. B&W's Companion system is available in multiple configurations depending on your truck model; confirm that your specific Companion arm set (sold separately or as part of a complete kit) is rated for your trailer's gross trailer weight (GTW) and pin weight.
The GNRC912 integrates with the Companion arm assemblies that pin to the gooseneck ball shank. The center section drops onto the arm pivots and locks in place. No drilling or permanent truck bed modification is required beyond the existing Turnoverball cutout. The jaw mechanism should be lubricated at the beginning of each towing season and inspected for wear before long trips.
