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.

Review from a similar BX1 in Gooseneck Coupler


Honestly i feel short changed the welds should really be 100% across regardless of whether necessary or not. Some oil so it didnt rust during shipping would of also been appreciated but again not end of the world. The welds appear to be robotic if they're by hand they did an awesome job.of what was done but again, for the time to finish the seams wouldnt of been a real big deal on the production side, but i sure do appreciate the capacity its rated and i plan on using it to its fullest. Thanks again

Review from a similar BX1 in Gooseneck Coupler


I had a fixed neck on my 32' cattle trailer and with the newer trucks the ball sits so high that my front axle on the trailer was barely touching the ground. After replacing the fixed hitch with the bx1 my trailer rides level. It does exactly what I was hoping it would do!! GREAT PRODUCT!!!

Review from a similar BX1 in Gooseneck Coupler


Great, well built product and support. I had several questions about this product and someone from their technical support team promptly responded multiple times until all of my questions had been answered. By far the best bang for the $$$. It would have been nice if it had come pre-painted or at least primed but the decals had peel off covers so you could simply paint it the color of your choice and then peel off the covers and it looks great. Very well built and sturdy product. Can't ask for more.

Julie at etrailer got me just what we needed and got it here in time for the move! We were replacing an older goose neck coupler that had become damaged. Although a original replacement wasn’t available Julie found a newer model that would fit and worked out perfect! Super easy to hook up the trailer with this new BX1 coupler!! Thanks!!

Excellent product and service. I replaced the hitch on my 36 ft PJ due to hole ripping out. I made a modification to the hitch to reinforce the hole as shown in pictures.

I ordered the bulldog bx1at 9:30pm and it was on my porch 3 days later. Absolutely amazing turn around time. Installed it the next day on a trailer project with no issues with the product at all. I will order from etrailer from now on. Great product and easy one handed operation.

Review from a similar BX1 in Gooseneck Coupler


I bought a dump trailer that had a 5th coupler on it. Switch to a gooseneck for the weight capacity and this has been a great coupler. Easy to use and holds tight. Pulled a lot of weight with it with no problems or damage. Would buy again if I needed one.


Comments
Coupler is still working great. Has some surface rust around the latch area since I did not paint it there. All and all still works good as new.

I needed this to get the goose lower on my lifted flat bed. My old tube had a partial double collar and could not get it any lower. This fit, has a great latch and no double collar. It arrived covered in surface rust, wish they came at least metal etched primed. Fast shipping as always from etrailer! Thanks!!

The customer service at etrailer is amazing! I had ordered a gooseneck coupler not realizing that was on back order until april. I called and explained what had happened and they quickly found a similar product that was in stock and ready to ship. I actually received it the next day. Everything fit and works just like it should. I will definitely be using and recommending etrailer in the future!

Review from a similar BX1 in Gooseneck Coupler


I replaced my old bulldog coupler with the newer BX1 coupler, it's so much nicer and easier to lock/unlock. I've not actually used it yet, I did locked the ball in the coupler on my original and the BX1 to compare and it was a much tighter fit. I can tell I'm going to love it - can't wait to pull my bobcat, I'm sure it's going to be a smooth ride.


Comments
Just hauled my bobcat 325 miles and my BX1 coupler did and awesome job! No worries pulling with this coupler...it’s so much safer than my old one.

Review from a similar BX1 in Gooseneck Coupler


Would not have been able to use trailer without it truck was to tall. Tons of misalignment is allowed for hooking up. If etrailer was smart they would sell the pin to lock the latch with the receiver. Can't use standard hardware because clearance is tight. Has to be the correct oddball Lynch pin. If they do sell it, make it like other sites 'customers frequently bought with this...'

Review from a similar BX1 in Gooseneck Coupler


I bought a 2017 Ford F250 which was higher than my 2011. I replaced a different bulldog hitch with this on my cattle trailer and was able to get more adjustment to completely level my trailer. I actually only used the insert. I really like the lock! The cupped design also makes it easy to go on the ball. I got a great product at a great price! Thanks guys!

  • 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.

  • Can Gooseneck Trailer be Leveled After Coupler is Attached
    You should make sure your level is trailer before coupling the Bulldog BX1 Gooseneck Coupler # BD1289140300 because as you can see by the cut out of the linked manual for this coupler: "The load bearing pin must be fully insough both the inner and outer tubes and the retaining pin installed inserted through both the inner tubes and outer tubes in order for the coupler to support its rated load." This would not allow you to adjust the height of the coupler with a fully supported load.

  • Replacement Inner Gooseneck Trailer Coupler Tube that Doesnt Use Load Bearing Pins

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.

  • Gooseneck Trailer Coupler Like # BDGN240200 Is Difficult To Operate
    Since the # BDGN240200 is a weld-on application. I am not sure if it would be easy to just change out the coupler on your trailer as it will require cutting and grinding to prep for the new weld. You may simply want to try some white lithium grease to see if that frees up the current mechanism a bit and makes it easier to unhook the trailer. It is designed to allow you to move the lever to open the jaws and pull the vehicle out. If that does not help you may want to consider either...
