The complete kit is GNRK1257. What is in this box is the center section: the machined receiver socket, the 2-5\/16\" gooseneck ball, the 5\/8\" steel locking pin, the spring loaded latch handle and the safety chain u-bolts. The under-bed frame and the vehicle specific brackets that hold it to the truck are in the mounting kit, which is the other box and is not included here. To end up with a working hitch you need this part and the GNRM1257. B\u0026amp;W ships the Turnoverball as separate boxes, which is why these halves can be bought on their own and are stocked as service parts. That makes this the right listing if you are replacing a damaged or worn half, moving a hitch between trucks of the same make, or completing a two box shipment where one box did not arrive. It is the wrong listing if you are buying a gooseneck hitch for the first time: order GNRK1257 instead. It suits the same trucks as GNRK1257: 2007-2021 Toyota Tundra Trucks. Assembled into its complete kit, the hitch is rated 30,000 lb gross trailer weight and 7,500 lb vertical tongue weight with the included 2-5\/16\" gooseneck ball, and never more than your own truck's tow and weight ratings.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's Included:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCenter section with solid one-piece machined receiver socket\u003c\/li\u003e\n\u003cli\u003e2-5\/16\" solid machined gooseneck ball, stows inverted in the receiver\u003c\/li\u003e\n\u003cli\u003e5\/8\" steel locking pin with spring loaded latch handle\u003c\/li\u003e\n\u003cli\u003eTwo spring loaded safety chain u-bolts\u003c\/li\u003e\n\u003cli\u003eNOT INCLUDED: the vehicle specific under-bed mounting kit (GNRM1257)\u003c\/li\u003e\n\u003cli\u003eNOT INCLUDED: this is not a complete hitch.

The complete kit is GNRK1257. We are saying this first and saying it plainly because it is the one thing that goes wrong when these parts are sold online. The other half is the GNRM1257.

It is also the half that actually wears, which is why it is kept as a service part.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTurns Over and Stows in Its Own Socket\u003c\/strong\u003e\u003cbr\u003eThe Turnoverball behavior this part is named for works the same whichever half you are replacing. Pull the handle in the wheel well toward you and rotate it slightly left to lock the pin out, lift the ball, turn it over and drop it back into the same receiver upside down. The bed goes flat. Rotate or push the handle right and the spring pops the latch back into place, ready to tow.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRated 30,000 lb gross trailer weight and 7,500 lb vertical tongue weight with the 2-5\/16\" gooseneck ball\u003c\/strong\u003e\u003cbr\u003eCapacity on a gooseneck depends on which ball is in the socket, so the number always carries the ball with it. With the 2-5\/16\" gooseneck ball supplied in this kit the rating is 30,000 lb gross trailer weight and 7,500 lb vertical tongue weight. B\u0026amp;W's own position, printed in the Turnoverball owner's manual, is that the hitch is rated to tow what your truck is rated to tow. Look up your truck's GVWR, GCWR and maximum tow rating before you load a trailer, and treat the hitch numbers as a ceiling you work under rather than a target.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFits the Same Trucks as GNRK1257\u003c\/strong\u003e\u003cbr\u003eThis part belongs to GNRK1257, which B\u0026amp;W lists for 2007-2021 Toyota Tundra Trucks.

Roger Baker and Joe Works, the B and the W, were building custom truck beds when they got tired of the one thing every gooseneck customer complained about: a ball welded permanently into the bed, in the way every day of the year for the few days a year it was actually towing. They designed a hitch that mounted underneath the bed and a ball that turned over and stowed in its own receiver, and the Turnoverball Gooseneck Hitch was born. A few years later the same under-bed mounting system became the single-point Companion fifth wheel hitch, which is why a Turnoverball socket still accepts a Companion today.\u003c\/p\u003e\n\u003cp\u003eEverything B\u0026amp;W sells is still made in Humboldt. Roger retired in 1999, and in 2007 Joe began transferring ownership of the company to its employees, so the roughly 600 people working in the plant today are also its owners. They buy American steel on purpose and say why: the sheet steel comes out of Burns Harbor, Indiana, and the round bar that becomes the gooseneck ball is drawn at a mill in Norfolk, Nebraska, because when the strength of a piece of steel is the only thing between a truck and a loose trailer, B\u0026amp;W wants a mill it can hold to a specification.\u003c\/p\u003e\n\u003cp\u003eTheir testing story is worth knowing before you compare hitches on price. SAE J2638 is the performance standard for gooseneck and fifth wheel hitches, and B\u0026amp;W is blunt that it is only a recommended practice, not a legal requirement to sell one. The standard allows a manufacturer to use a fresh sample for each of its nine tests. B\u0026amp;W's own engineering requirement is stricter: a single hitch has to survive all three 300,000 cycle dynamic tests and then still pass the six static tests, because, as their director of engineering puts it, an accident rarely happens when a hitch is brand new, it happens after years of wear from the road.\u003c\/p\u003e\n\u003cp\u003ePrestige Truck is an authorized B\u0026amp;W dealer. Every hitch we ship is new, in the factory carton, and covered by B\u0026amp;W's Lifetime Exclusive Limited Warranty direct from Humboldt.\u003c\/p\u003e","brand":"B\u0026W Trailer Hitches","offers":[{"title":"Default Title","offer_id":49106958516468,"sku":"GNRC1256","price":329.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0805\/4784\/0244\/files\/bw-turnoverball-center-section-for-gnrk1257-gnrc1256.png?v=1786364118","url":"https:\/\/prestigetruck.com\/products\/b-w-turnoverball-center-section-only-for-gnrk1257-gnrc1256","provider":"Prestige Truck","version":"1.0","type":"link"}
