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.

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!!! 240883

This coupler honestly exceeded our expectations! My husband was extremely impressed with it and we will be buying these couplers in the future for trailers we purchase. They are heavy duty and I can't believe the low price for the quality of product! Very satisfied customer and will definitely buy from etrailer in the future! 409204

Came home from work to the package on my front step after 6 days, opened it like a kid on Christmas and was more than happy with the product. As heavy duty as you can make it for a great price. It's going to work perfect on my 30ft horse trailer and my lifted pickem up truck. 437695

Excellent quality, and the cupped end of the coupler makes it extraordinarily easy to hitch up even when alighnment isn't perfect. Used it to replace the oem coupler on a used trailer and gain more clearance between tongue and bed. Perfect choice. 478555

Product was exactly as advertised and delivered early. Thanks etrailer!! You've won myvote of confidence!! 124329


Comments

After a year in operation the bulldog hitch is performing perfectly. I had to go with this coupler to level out the trailer so that the weight was evenly distributed over both axles. I actually think this is helping with tire wear and blowouts. Very pleased!!! Thanks e trailer.

Review from a similar Bulldog BX1 in Gooseneck Trailer 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. 227654

Review from a similar Bulldog BX1 in Gooseneck Trailer Coupler


There is not a locking load bearing pin manufactured to Bulldog's knowledge that fits these types of tubes. People usually steal the trailer and not the tube (unfortunately for me the idiots stole my tube and not the trailer). Standard coupler locks are 1/4" shank usually, and the end of the load bearing pin has a .20" hole for the retainer pin. Bulldog sees no reason why it couldn't be drilled out to support a 1/4" coupler lock that will fit on the end of the 3/4" diameter load bearing pin. I have not yet performed this modification of the load bearing pin, but will upload pics once complete. 455175

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!! 527920

Review from a similar Bulldog BX1 in Gooseneck Trailer Coupler


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! 314866

The product was great, and Noah was even better! He gave his personal number to call if we had issues(which we didn’t), the reviver came to me in 2 days free shipping, and was an exact fit. And is already on its way to a horse show!! We are a larger high end boarding/show/ beach ride facility, and use multiple trailers on a daily basis, will definitely be shopping here again next time the new girl breaks something 504247

I was in a bit of a hurry for the gooseneck coupler to use for a trip to Colorado. I got it in 3 days which counted the day I ordered it. It was exactly what I had ordered and fit my trailer as if it was original equipment. It was also the most economically priced. When making inquiries for needed equipment I will do so at ETrailer first. Thanks ETrailer for a great price and product. 216390

Review from a similar Bulldog BX1 in Gooseneck Trailer Coupler


Very pleased with our BX1 coupler. We had put in new springs on our Ford Superduty which raised the truck bed up 4+ inches. The coupler allowed us to keep using our horse trailer and maintaining the trailer close to level. Shipped to Ontario Canada in short time. Whenever changing the coupler height, be aware of the spacing between the floor of the gooseneck and the top of the truck bed. 384877

I ordered this item by phone on a Friday & it was at my door on the following Monday. Great service & great product quality. I have not changed out the part yet - hopefully soon - when the weather breaks but I am very satisfied with the prompt service I received. I would recommend this company for any trailer parts you might need. I was also thrilled with the free shipping, Thank You. 176755

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...' 436956

Review from a similar Bulldog BX1 in Gooseneck Trailer 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. 324986


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.

Installed to lower the nose height on my horse trailer. This was my only option and am quite pleased with it. I pull an Elite 4 horse with a 19' living quarters behind a Peterbilt 335. The truck has a trailer saver air hitch. The latch mechanism just clears all the way around and is truly a one-hand operation. Very happy! 378981

Review from a similar Bulldog BX1 in Gooseneck Trailer Coupler


I needed to replace my coupler with the new BX1 type, because I have a very high ball mount (44" ground to base, Freightliner M-2 truck ). The old coupler would not allow tube to raise enough to allow the trailer to be towed level. This works perfectly, and service was great. Thank You etrailer.com 105313

Review from a similar Bulldog BX1 in Gooseneck Trailer Coupler


All the reviews said this is good for higher vehicles, to level a load. The distance from bottom hole to gooseneck is 10.5 inches, exact same hight of the coupler that came standard on my trailer. The raw finish comes with a nice coat of rust on it, so be prepared to clean all that up as well. 437240

Review from a similar Bulldog BX1 in Gooseneck Trailer Coupler


Replaced my old one with this on my 20k GN as it was getting hard to unlatch. This one also helps with hooking up with the large opening and you can lock it with a padalock. The latch design is easier than the old style and easy to tell if it is latched or not. 365487



- BD1289050300

by:

Review from a similar Bulldog BX1 in Gooseneck Trailer Coupler


Great design. More adjustable because it lets you slide it all the way up to the latch, which means you can get it 7" higher than a conventional style gooseneck coupler. It's concave shape allows it to slide onto the ball easier also. Wish it was made in America. 347858

Do you have a question about this Gooseneck Trailer Coupler?


  • 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...

  • 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. It is rated for 30,000 lbs, has a retracted height of 24-1/2 inches and has a vertical range adjustment of 8 inches. This gooseneck coupler also comes with a Limited 5-Year Warranty.

  • 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.
