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 Inner Gooseneck Trailer Coupler Tube that Doesnt Use Load Bearing Pins

  • Square Gooseneck Coupler For Trails West Combo Horse Trailer
    From my research it looks like the Trails West combo horse with living quarters 2005 model has a square Bulldog Gooseneck Coupler. All of the square inner tubes available have the holes for the pins. A lot of trailer manufacturers have switched from set screws to lock pins for safety reasons. It may be best to just replace your whole gooseneck coupler with Bulldog BX1 Gooseneck Coupler part # BD1289140300.
