Today we'll be reviewing part number BD0289640300. This is the Bulldog Gooseneck to 5th Wheel Trailer Coupler Adapter. It's going to have a weight capacity of twenty-five thousand pounds. The Gooseneck to 5th Wheel Adapter lets you tow your gooseneck trailer with a 5th wheel hitch. The round inner tube will fit most standard round gooseneck outer tubes. Tube diameter's going to measure four inches from outer edge to outer edge.
This is a direct replacement for the inner tube on Bulldog Gooseneck to 5th Wheel Coupler Adapter, part number BD0289580300. That's going to be sold separately. It does have the adjustable height with the four hole design. The distance from the center of one hole to the center of the other is going to measure two and three quarters of an inch, and that's going to be the same distance between each hole. It's made from a durable steel construction with a nice raw finish on it. Again, that outer tube's going to give us a diameter of four inches, weight capacity, twenty-five thousand pounds.
The plate here at the base is going to give us a measurement of eleven inches by fourteen inches. Then the kingpin's going to be the industry standard two inch diameter. That's going to do it for our review of part number BD0289640300. This is the Bulldog Gooseneck to 5th Wheel Trailer Coupler Adapter. .

Pull your gooseneck trailer with a fifth-wheel hitch by installing this round gooseneck-to-king-pin adapter. Inner tube fits most standard, round gooseneck coupler outer tubes.My expectation when I unboxed the unit was that it would be a brand new unit. This unit looks like it had been made up and peicemealed from random gooseneck parts. I am reluctant to use this unit because I am questioning the workmanship of the welds. 708317
Victoria B - 10/15/2019I own a small transportation company and needed a way to minimize hookup time for one my drivers that primarily pulls fifth wheels hookups. We bought a 30 ft gooseneck trailer and found we needed a faster solution. We reached out to etrailer and they had solution that worked perfectly. Also, we were able to get our hitch conversion within 3 days limiting our downtime. I will buy from these guys again!!!! Excellent service.... 231711
Works great. Now I don’t have to use the tractor to pull the heavy B&W hitch with the pog system everytime I need to pull the gooseneck. I did have to drill the holes for the pin since the coupler was not a bulldog brand. Pulls better on the king pin than the gooseneck ball also. Great price. Will shop again soon. 646610
The holes through the round tube insert for pinned height adjustment are not at a right angle to the square plate. I am not sure if it's designed that way on purpose or not. I would have thought it would have went exactly cross ways and not at an angle? The pictures look like the holes are for the pins to go straight thru from the side. I will not be using this feature at this time but maybe in the future. It's welded great and not warped and appears square in good shape but does have some rust. Primer at min would be helpful. It arrived very quickly about 2 travel days plus the weekend, 1 day ahead of schedule. This should solve the problem of leaning/ rolling trailer on the goose neck ball for high leverage loads by converting to anti sway 5th wheel set up. 458153
Great product. Very well built. I am a farmer and use it to hook up a goose neck trailer to our semi. We use the trailer to haul hay, machinery, or even cattle. What's great about this product is that you can move it from trailer to trailer. This adapter will fit in a gooseneck trailer with the pin running through the side or with the bolts on the front. Overall great product for the farm. 420980
Bought this so my wife could load and unload our 30' flatbed easier. The gooseneck required her to climb into the bed and was hard for her to line up. This adapter installed in less than 60 seconds and has made her new career as a hot shot driver that much more enjoyable. I couldn't be more happier. 445862
I have ordered alot from etrailer and always been pleased , last week I ordered a 5th wheel conversion for my gooseneck trailer then went outside and literally cut my gooseneck hitch off , i then got a call from etrailer saying the part I ordered was backordered and was not available .while I was disappointed I was so glad called me immediately and was able to come up with a alternative . Great customer service ,I can not say enough great things about etrailer 492683
The king pin post I got from you works great I did have to grind the gusset down A little to get the trailer to set level. I was hooking it to a semi truck. That is higher then A pickup. Thank you. D.A. Kramer 463094
This item is ONLY for Bull Dog tubes requiring a 15 degree offset. I did not know this until after putting it in my none Bull Dog tube (I have a Lippert chassis). Tested after installation and the offset was so pronounced that it caught on my receiver. Talked with manufacturer's technical expert, and he said that the industry standard is 15 degrees. Regardless, the adapter is expertly fabricated and of good strong steel. Just wish it worked for my trailer. etrailer.com was very good trying to resolve my concern to point Donna spent a lot of time researching a solution for me. Ultimately I shipped back the adapter because it was not doable for me. We both learned a lot today about trailers and the limitations on Bull Dog adapters. 461653
Michael - 12/20/2018I bought a fifth wheel camper trailer and mounted a B&W Companion hitch onto the gooseneck hitch in the bed of my truck. It is such a pain to take in and out, so I bought one of these for my horse trailer to see how they work. They work great, so great in fact that I bought two more for my stock trailer and flatbed trailer. The only negative I have is that the holes in the sides of the pipe for bolts, pins, etc., are not located 90 degrees from the front of the hitch plate and therefore will not line up with the holes in most receivers on the trailers. They are apparently drilled before the plate is welded on, because none of the three I bought are in the same relationship to the front of the plate. 369013

Great product 729417
I haven't used it yet but it looks well built and I am sure it will fit the bill. The shipping was great and it got here in record time. I also liked the Tracking program on your website. It made tracking a lot easier and was kind of interesting with the map. 729358

Good price and free shipping. Couldn’t beat it. Easy to install. 679765
The bottom or last hole is 1/2 hole off to use it. Also the holes and plate is off about 10 degrees from being straight. I’ve got to find a welder or some one to redrill the bottom hole 650687
Awesome product. Easy to use and install. Has held up well for over a year with no problems. A great shopping experience. 645018

The product has performed flawlessly 100% Satisfied. 635656
These guys are awesome! Super fast and a great product- exactly as advertised! The gooseneck to fifth wheel trailer adapter was easily installed. Shipping took only a day and packaging was exceptional. 634201
As always, excellent service and support. I called Donna at etrailer to verify dimensions of this replacement 5th wheel adapter pin. Her answers were 'on target' and I was able to comfortably place the order through her. What I wasn't expecting was receiving the component 21 hours after the order was placed! Admittedly, this was a example of timing hitting all the right marks but anything I have ever ordered (lots) from etrailer arrives within two to three days.....usually exceeding my expectations. etrailer will continue to be my 'go to' first stop for my trailering needs. Great website, great service, fair pricing, fast delivery......perfect! 633303
