With superior steel construction, an adjustable-height design, fast and easy hookup and disconnect ability, and a tight fit around the ball for ultimate security, this gooseneck coupler is perfect for your heavy-duty towing needs.


Replacement on our hay trailer was the call for the hitch. It was easy to weld on and I like the pin on this hitch. It never moves like ones that are just jam nut tight. Can run down the road and not worry that this hitch will move out of ajustment. Fast shipping and a great company to work with.


Cut the old one off welded this on great adjustability for the new higher box pickup trucks


Product is exactly what I needed for my 30 ft cattle trailer. Heavy duty material that will last longer than the trailer. Would definetly recommend this product to others.


Quick shipping on a quality product with a great price


Heavy duty and easy to operate. I cut off a fifth wheel hitch and install this Bulldog
gooseneck coupler which cleans up the bed of my truck by ridding it of the fifth
wheel mount.


Great product and delivered at the right time. Staff very helpful. I wished I had ordered the Bulldog Gooseneck Coupler Adjustable Round 2-5/16 Ball for my Trailer sooner. I went all over the place looking for the item. I needed it in a hurry and I found it here and it was delivered as promise and I was happy as a farmer could be. Thank you very much for my Item: BD0289500300


I bought the gooseneck coupler hoping it would fit and it did. It took my uncle about half an hour to replace the old one with the new one. The service was quick. I received the product in 3 days. I'm happy with my buy.


Great product, fast delivery, incredibly easy to install. I will most definitely be ordering all my parts from for this project from etrailer.

  • Will the Bulldog Gooseneck Coupler, # BD0289500300 Fit Into an Existing Gooseneck Trailer Assembly
    In order to determine if the Bulldog Gooseneck Coupler, # BD0289500300, will fit in your existing trailer assembly, you can measure the inner diameter of the assembly. The inner diameter will need to be greater than 4 inches. You most likely would not need the outer tube since it sounds like you already have one. However, if you decided to replace the whole assembly,, the outer tube would need to be welded to the trailer by a qualified professional. Since the old coupler came off the ball...

  • Replacement Round Gooseneck Coupler For Lakota Horse Trailer
    I recommend Bulldog Gooseneck Coupler part # BD0289500300 which has a 30,000 lb capacity and set screws. This particular coupler is the inner and outer tube so it would replace the whole coupler on your 2007L Lakota Horse Trailer. It is a 4-1/2" outer tube that would need to be welded on by a professional welder. If you are trying to replace just the inner or outer tube I would need to know the diameter of the tube and the brand if you can find it on a sticker that would be helpful.

  • Outer Diameter of Inner Pipe on Bulldog Gooseneck Coupler # BD0289500300
    The inner tube on the Bulldog Gooseneck Coupler # BD0289500300 referenced in your question has an outer diameter of 4 inches and an inner diameter of 3-5/16 inches. This adjustable gooseneck coupler features a weight capacity of 30,000 pounds and a range of adjustement of 8 inches.

  • Is the Inner Tube Portion of Bulldog Gooseneck Coupler, Part # BD0289500300 Available Separately
    We do offer just the inner tube portion for Bulldog # BD0289500300 gooseneck coupler. That part # is BD1289050300. I do see that you have already ordered the entire gooseneck coupler, part # BD0289500300. Given that your original coupler could potentially have hidden damage or have been weakened by the accident, your decision to replace the entire unit is the right choice for safety reasons.

  • Can a Hole be Drilled in Gooseneck Trailer Outer Tube to Install Adjustable Coupler
    You would need to contact the trailer manufacturer to see if you can safely use the trailer after drilling a hole for an adjustable coupler such as # BD0287610300. the outer tube would have to have one to use this type of coupler so provided there was a hole and the trailer manufacturer was fine with adding one then you could use it. The outer diameter of the coupler tube is 4 inches so the inner diameter of the outer tube needs to be slightly larger for it to fit. Another option, which...

  • Replacement Gooseneck Coupler for Trailer with Set Screws
    The tube part # BD1289050300 that you referenced is not designed for use with set screws. It is designed for a pin that runs through it and the outer tube. Best option we have would be to go with the Bulldog Gooseneck coupler part # BD0289500300 which comes with a new outer tube that you could replace your trailer's with.

  • Can A Hole Be Drilled In Trailer Gooseneck Coupler To Use Replacement Coupler Outer Tube
    You will need to contact the trailer manufacturer to see if there is a problem with drilling a hole for the pin in the tube on the trailer to use with the # BD0287610300 inner tube. This tube has a diameter of 4 inches so you want to make sure the outer tube you have can accommodate the tube. You may want to consider another option which is to remove your old coupler and use a new one like part # BD0289500300. This should be installed by a qualified welder.

  • Bulldog Gooseneck Coupler Repair Kit For 30,000LB Gooseneck Coupler # BD0289500300
    Yes, the Bulldog Gooseneck Coupler Repair Kit # BD0287740300 has been confirmed by Bulldog to work on the Bulldog Gooseneck Coupler # BD0289500300. Their engineers have tested this and confirmed that it will work on the 30,000lb coupler as the difference between the 20,000lb and 30,000lb couplers is the thickness of the tube. They both use the same coupler parts beyond the tubes.

  • Gooseneck Coupler Recommendations for a Pace American Trailer with Gooseneck King Pin
    It sounds like you have something like the part # BD0289590300 on your trailer now and you are looking for a way to convert it to a gooseneck hitch that is designed to couple to a gooseneck ball. Which the only inner tube gooseneck hitch that would fit your square 4-1/2 inch outer tube would be the # BD1289210300. A better solution might be to completely remove what you have on your trailer and install an entire new assembly like part # BD0289500300.

  • Troubleshooting Gooseneck Hitch that Won't Lock onto 2-5/16 inch Ball
    It really sounds like your gooseneck hitch is designed for a 3 inch gooseneck ball. I know you said that you attached to your friends B and W hitch, but B and W offers a 3 inch ball # BWGNXA2025. The 3 inch setup is less common but it is still seen out there. If your trailer is larger it is very possible that you need a 3 inch ball. Which there are no adapters like the Spyder that have 3 inch balls. This would call for the replacement of your coupler or the install of a gooseneck hitch...

  • What Is Needed For More Clearance Between The Bed Rails And Gooseneck Trailer On A Ford F-150 Truck
    A good rule to follow is to allow 6 inches or more of clearance between the sides of the bed and the bottom of the gooseneck trailer to allow for dips and bumps in the road. You will want to check your gooseneck coupler to see if it has an adjustable tube with set screws that will allow you to adjust the height of the coupler for extra clearance when attached to your vehicle. If it does then you can loosen the set screws and adjust the length of the tube to get more clearance. If the...

  • How to Install Gooseneck Coupler BD0289500300 on a Trailer
    Gooseneck coupler # BD0289500300 is installed by welding it, using gussets, directly to a trailer with no existing coupler or fifth wheel attachment. This coupler is not a 5th-wheel to gooseneck adapter, but a coupler meant to be installed on a naked trailer. If you have an existing 5th-wheel kin pin on your trailer, a better choice for you would be to use a 5th-wheel to gooseneck adapter like # CAB-C5G. Using this adapter would be the easiest way to equip your current fifth wheel trailer...
