Great product for my unique application, i bought an older gold rush trailer with an inverted fifth wheel and this made it as easy as dropping it in and going!
by: Debra B.03/20/2016
We had gooseneck hitch in our truck and didn`t want to be out the money or time to change it to haul fifth wheel trailer so this product is great . Very well built and easy to use.

Another quality attachment from B&W to go with the best hitch design on the market!
by: Jerry12/03/2018
Took out my old hitch and bought this turn over attachment just the weight of it was obvious of how heavy duty it is! The finish and machining is excellent and compact.

- Size of Plate on B and W Inverted Fifth WheelIf you have a B and W Turnoverball hitch the inverted fifth wheel hitch # BWGNXA4000 is the only option we have and it has an 8 inch plate.
view full answer... - Recommendation to Tow Trailer that has Inverted 5th Wheel Hitch with 2012 Ford F-250To tow a trailer with an inverted 5th wheel hitch using the already installed B&W Turnoverball underbed gooseneck hitch on your 2012 Ford F-250, you will just need to add the Turnoverball King Pin Adapter # BWGNXA4000. This will insert into the hitch hole of your B&W gooseneck hitch to convert it to an in-bed king pin, allowing you to tow your trailer. I have attached a short video demonstration on this product so you can see exactly how it works.
view full answer... - Outer Dimension of Square Tube for B&W Turnovrball King Pin Adapter # BWGNXA4000The base of the B&W Turnoverball King Pin Adapter # BWGNXA4000 is 2-1/2 inches by 2-1/2 inches square. This adapter was specifically designed to fit in a B&W Turnoverball gooseneck trailer hitch. I have linked the above mentioned product to this page for your viewing and purchasing convenience.
view full answer... - What is the Benefit of an Inverted 5th Wheel Hitch Head on a 5th Wheel TrailerOne really big advantage to having and inverted 5th wheel hitch head on the trailer is that it is uncommon so that makes the trailer harder to steal. Another advantage is that its a little easier to hook up with a 5th wheel set up than a ball because the king pin can funnel into the hitch jaws. And on most 5th wheel set ups safety chains are not required but that can vary depending on the state so it is a good idea to just use them anyway. Since you already have a B&W Turnover Ball hitch...
view full answer... - How To Tow a Trailer with Inverted 5th Wheel HitchThe only option we offer for using a trailer inverted fifth wheel hitch is the B&W Turnoverball King Pin Adapter for Trailers with Inverted 5th-Wheel Hitches part # BWGNXA4000 which requires the B&W Turnoverball Gooseneck Hitch. If you can let me know the year, make, and model of the truck I can make sure you get the correct one.
view full answer... - Is Location of B&W Gooseneck Adapter for Inverted 5th Wheel Hitches Compatible with 2019 Ford F250When Ford went to the aluminum beds, the position where that hole needed to be changed. Once B & W became aware of this change, they added an elongated hole to the # BWGNXA4000 to allow for the changed position of the retaining pin. This change was implemented in 2017, and all our current stock is of the updated kingpin adapter that will work perfectly with your 2019 Ford F250
view full answer... - How to Tow 5th Wheel Trailer with Inverted Hitch with Truck That Has Gooseneck HitchI am sorry but we do not have a round shank gooseneck adapter to allow you to tow an inverted hitch 5th wheel trailer. We offer only the B&W Turnoverball King Pin Adapter # BWGNXA4000 that you mentioned and the # BWGNXA4025 which allows use of an inverted gooseneck hitch; both of these do have square shanks. But I do have another type of solution for you: a replacement 5th wheel pin box called a Goosebox. A Reese Goosebox is just like a standard 5th wheel king pin except it is designed...
view full answer... - Weight Capacity of the B&W Turnoverball King Pin Adapter # BWGNXA4000The B&W Turnoverball King Pin Adapter # BWGNXA4000 shares the same ratings as the B and W Turnover Ball Hitches it is designed to fit like the part # BWGNRC962. This product has a 30k total trailer capacity and 7,500 pin weight.
view full answer... - Gooseneck Hitch Setup that Can Tow Gooseneck Trailer and Inverted Fifth WheelI really wish there was a gooseneck to inverted fifth wheel adapter available for Curt hitches but the inverted fifth wheel setup is so rare there really isn't much of a demand for that type of adapter. The only setup I can recommend is the B&W Inverted fifth wheel adapter part # BWGNXA4000 but it will require you to replace your Curt gooseneck with a B and W part # BWGNRK1108.
view full answer... - Parts Needed To Tow Trailer w/ Inverted 5TH Wheel Hitch Using a 2021 Ram 3500 w/ Factory Puck SystemThe B&W Turnoverball Underbed Gooseneck Trailer Hitch # BWGNRK1320 will allow you to replace the center factory puck system mount on your 2021 Ram 3500. This will then allow you to use the B&W Turnoverball King Pin Adapter # BWGNXA4000 for trailers with an inverted 5th wheel hitch.
view full answer... - Needing to Pull a Gooseneck Trailer with a 5th Wheel HitchI have a solution for you, however, the B&W Turnoverball King Pin Adapter, # BWGNXA4000, is designed to drop into a B&W Underbed Gooseneck Hitch, like # BWGNRK1197, and tow an inverted 5th wheel hitch. In your case, if you are towing a gooseneck trailer with a 5th wheel hitch, your best option would be to use a Gooseneck-to-5th-Wheel Trailer Coupler, like # BD0289640300. Replacing the inner tube on the gooseneck with this adapter will allow you to connect the trailer to a 5th wheel hitch....
view full answer... - How to Tow Gooseneck Trailer with Inverted 5th Wheel King Pin with 2019 Ford F-250 Factory PucksI do have some potential solutions for you, however there's not an adapter or system available that will allow you to pull a trailer with an inverted 5th wheel head behind your Ford F-250 that's equipped with the factory puck system. You could potentially remove the factory puck system but this is going to require some pretty significant modifications. I might even check with a local Ford dealer to see how this can be done and to make sure it's not going to affect the integrity of the...
view full answer... - Can Truck with B and W Turnoverball Gooseneck Hitch Tow Trailer with Inverted Fifth WheelB and W offers a king pin adapter designed to fit their Turnoverball hitches like the part # BWGNRK1108 that you referenced. For that you'd want the part # BWGNXA4000. You should note that this is for inverted fifth wheel setups and not standard fifth wheel towing. B and W does offer standard fifth wheel hitches to fit the Turnoverball hitches as well like the Companion part # BWRVK3500.

- Parts Needed to Tow a 5th Wheel Trailer with Inverted Pin Box with a 2018 Chevrolet Silverado 2500I do have a solution for you, but we typically recommend going with a sliding 5th wheel hitch when towing a 5th wheel trailer with a truck that has a bed shorter than 8 feet. For your 2018 Chevrolet Silverado 2500 with a 6-1/2 foot bed I recommend installing the B&W Turnoverball Underbed Gooseneck Trailer Hitch # BWGNRK1016 and then using the B&W Turnoverball King Pin Adapter # BWGNXA4000. This adapter allows you to tow your trailer that has an inverted 5th wheel pin box and can easily...
view full answer... - Fifth Wheel Adapter Options Other Than King Pin to Gooseneck BallWe don't have a 2 inch receiver application, but we do have the B&W Turnoverball King Pin Adapter for Trailers with Inverted 5th-Wheel Hitches # BWGNXA4000 which is a 2-1/2 inch outer measurement on the solid square. We also have the Fifth Wheel Trailer King Pin # 337KP20050 with no connection on the backside if you need to make a custom adapter If you are looking for a gooseneck to king pin connection, we have the Gooseneck to 5th wheel adapter inner tube # KPG5-Q25-IP which has a 4...

If you have an inverted 5th wheel hitch on your trailer then you can use the B&W Turnoverball King Pin Adapter for Trailers with Inverted 5th-Wheel Hitches # BWGNXA4000. If you have a more normal king pin (not inverted), then you can mount a B&W Companion hitch in the gooseneck mount. I have listed...
view full answer... - How to Tow 5th Wheel Hitch w/ 2008 Ford Super Duty with In-Bed KingpinThe in-bed king pin is kind of an oddity that isn't terribly common. How to proceed will depend on whether you'll need to continue to use the in-bed kingpin. If you will, your best bet would be to remove the existing kingpin and install a B&W Turnover Ball, part # BWGNRK1108. When you need to tow the trailer with the inverted fifth wheel hitch, use the # BWGNXA4000 adapter. When you need a standard non-inverted fifth wheel hitch use # BWRVK3500-5W. Or if you have a short bed truck, you'd...
