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.I 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
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
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
Ended up paying a welding shop to cut and welding it in place because it hung down too much on the lowest setting putting stress on rear axle. Fixed the receiver plate 15 degree offset by cutting the plate off the tube removing the 15 degrees. Glad the Bull Dog was a raw product which allowed modification. Spent an extra $150 in mods to get what I needed.
Michael - 12/20/2018Bought 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
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
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
I 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
I love these adapters. They make it possible to use my truck's 5th wheel hitch for my rv trailer, stock trailer and flat bed trailer (plus, they are much easier to hook up than the gooseneck hitch was). I would recommend these adapters to anyone. Thank you for checking back with me. I am very pleased with the service your company has given me over the years.
Larry L - 04/18/2018The 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
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
Awesome product. Easy to use and install. Has held up well for over a year with no problems. A great shopping experience. 645018
Looks good thanks 644131
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
Looks great haven't installed it yet but thank for making my live easier 612522
Was impressed at the quality of the pro duct!! 611747

Works awesome just as expected great price
Lucas - 03/17/2019Great product 481117
Very good quality shipped on time and when I was told it would. 480144
Was very well built. Had to do a little fabrication to my trailer to get the height right but metal in stem was plenty thick to weld to 468817
Craftsmanship looks good, and it was shipped promptly. *Note* raw finish means you will have to prep it for whatever coating you want to put on it. I painted it to match my trailer. 465944
Lisa D made ordering a joy, so familiar with the product I was seeking. Ordering was quick and to the point. She made me feel like she enjoyed her position and helping a customer. Product was received promptly and was indicated . 444000

Still working it hard today thank you. 439243
Product arrived promptly; and was as expected, and in good condition. Packaging was appropriate. Product works! I painted mine. I would definitely order from this company again. They have a lot of stuff for different kinds of trailers, and parts that are hard to find in any store. 429740
works great 410055
I like the workmanship, Except for height adjustment hole locations. The degree of the holes makes the kingpin plate Off Square. It will work ok. 399881
easy to install, works great for my application of hauling horse trailer with semi truck 372597
Love the product. Great conversion only 2 issues (can't use lowest hole due to supports being to high up the tube as well as the plate is not sitting square. it's off about 30 degrees when pin is put through hole.) Would buy it again and recommend it just a few things. 371607
The product is still working perfect and the best purchase ever. Thanks
Robert J - 05/12/2018I received the package in great timing. I am pleased with the hitch and the price. I will order from you again. 366830
Works as described good product 366739
My wife and I use a heavy gooseneck flatbed on our farm .We also have a fifth wheel rv. This makes the hitch interchangeable. We regularly load 10 tons on the flatbed and have had no problems . 365860

This is the third adapter I have purchased from etrailer. One for my horse trailer, one for my dump trailer and now one for my equipment trailer. A little bit of time to paint and install and everything is fine. No more climbing in the pickup bed to hook and unhook, no chains to deal with. I prefer the 5th wheel to the ball gooseneck, much easier hook up when you can't see the ball in the bed of your truck. Quality is very good and they work. You won't find it cheaper anywhere else and they always ship quick. 357080
Still doing what they are supposed to do and holding up very well. No complaints.
JOSEPH H - 03/23/2018have not used it yet but it will do the job 356914
Have used it for a year with no problem s! 352600
Yes we love it! It made the switch so much easier and has been used a lot, we couldn't be happier. Thanks! 351604
I converted my horse trailer to a fifth wheel set up form Etrailer. It was easy and works like a charm. 347810
Worked like a charm, haul for a living and slides right in every circle gooseneck hitch. Only recommendation for company for buyers is to clear coat it because when not in use it will surface rust with in a couple days. Otherwise affordable quality buy! 344645
fit rite in works great! 343961
