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.

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

We actually used the product in production of a new trailer, so I do not have access to it any longer. However, I am certain it is still doing well for my customer, as I have not heard otherwise.



by:

This is a well made coupler. I use it on a custom made trailer that hauls backhoe and excavator daily. The lock/unlock mechanism is easy to use.



by:

We received the product in a really good condition.


Thanks

Excellent service and prompt delivery.

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!!!



by:

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.



by:

My f800 Ford has a tall hitch height . This allowed me the extra distance I needed to tow my trailer . Very low profile .



by:

Have gotten this product before. I like how easy it makes hooking up the trailer.



by:

Great product! Exactly what I needed and wanted. Shipped fast, budget friendly



by:

Great price and fast delivery! They kept me informed about the delivery.



by:

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!!



by:

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.



by:

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.



by:

The insert came, shipping was fast and packaging excellent, but here's the rub, it will not fit into the sleeve. It looks just like the one that slip out and the hitch part looks super, but it is probably a sixteenth in circumference too large. Will not fit into the sleeve without lot of grinding. Grrrrr!



by:

The coupler was on back order for a little over a year, I understand that it was out of etrailer’s hands due to supply issues. The other slight problem was that I would have thought that the industry should have a standard, my trailer hitch is 4” square tube ghe coupler came and would not fit I had to mill ir to fit. etrailer people were nice and cooperative in checking on the order and offering other options but I told them I would wait on the one I ordered.



by:

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.



by:

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.



by:

It does the job



by:

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!



by:

This tube/ball hitch gave me the additional space I needed to lower the front of trailer to level. The locking handle is easy to use with one hand, no more of the two hand strand to release coupler from ball.
The service etrailer provided was great and one year later they have contacted me to see how if any the could provide with any additional service. Will do further business with them when necessary. Thank you etrailer!



by:

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...'
