The BX1 gooseneck coupler from Bulldog is designed to provide the easiest, most secure hookup possible. The bottom locking plate on this coupler is 50 percent larger than the competition, providing additional surface area to guide the ball into the socket. Miss the target by just over an inch and the coupler will still engage.


Bulldog BX1 Gooseneck Coupler Locking Plate

Once hookup is complete, use the easy-to-access, easy-to-maneuver handle to lock the coupler to the ball. When the handle is down, you know that everything is secure and it's okay to tow. For extra security you can insert a padlock (sold separately) through the fixed plate.


Once you begin towing, you may notice that there is far less rattle and jarring at the coupled point than you'd experience with a standard gooseneck coupler. This is because the ball pocket on the BX1 provides contact on both sides of the hitch ball, rather than on only one side, which is typical of the competition. The result is a tight fit around the ball that makes for a smoother, quieter and more secure towing experience.

  • Replacement Gooseneck Coupler with Outside Diameter of 4-1/2 inches
    You will want to make sure that the inside diameter of 4 inches is the same, but the Bulldog BX1 Gooseneck Coupler # BD1289040300 has an outside diameter of 4-1/2 inches and will fit the standard gooseneck ball size of 2-5/16 inches.

  • Replacement Inner Gooseneck Trailer Coupler Tube that Doesnt Use Load Bearing Pins
    As far as an inner tube only, the BX1 coupler # BD1289170300 is the only option. It sounds like you need one that is held in the outer tube with set screws such as # CG or # BD0287690300. Coupler # CG has a 4 inch diameter tube and # BD0287690300 has a 4-1/2 inch tube. The other option is to replace both the outer and inner tube with # BD1289040300, # BD1289030300, # BD1289000300, # BD1289080300, # BD1289070300, or # BD1289140300. These are all BX1 couplers for 2-5/16 inch balls and...

  • What Is the Outside Diameter of the Bulldog BX1 Gooseneck Coupler
    The outer diameter of the outer tube on the Bulldog BX1 Gooseneck Coupler part # BD1289040300 is 4-1/2". The length of the outer tube is 20". The outer diameter of the inner tube is 4". I don't have accesses to any of the mechanical drawing but if you need another measurement not listed above just let me know what that is.

  • Round Gooseneck Coupler Rated For 30,000 Lbs
    Since your setup is only are strong as it's weakest component you could not add the Bulldog BX1 Gooseneck Coupler Inner Tube - Round part # BD1289050300 to your outer tube and increase the capacity. If you need a 30,000 lb capacity gooseneck coupler, I recommend Bulldog BX1 Gooseneck Coupler - Adjustable Height - Round - 2-5/16" Ball - 30,000 lbs part # BD1289040300.

  • Replacement Bulldog 30k BX1 Gooseneck Coupler Recommendation for Trailer
    I have a better solution for you, but I can't really recommend you start drilling holes in your outer tube as that could potentially reduce the trailer's capacity and would most likely void some warranties. A better solution would be for you to remove your current outer tube and then install the # BD1289040300 instead as that would allow you to use the same style coupler as the inner tube that you referenced.

  • Towing a 5th Wheel Trailer with a Gooseneck Hitch in a 2011 GMC Sierra
    It sounds like your truck has a gooseneck hitch and your trailer has a 5th wheel king pin. In order to tow a 5th wheel trailer using a gooseneck hitch you will need an adapter. I recommend the Andersen Ranch Hitch # AM3100. I have included a link to a video review of this adapter for you.
