Bulldog Gooseneck Trailer Coupler - BD1289210300

Short base assembly is made of durable steel. Large bottom locking plate makes hookup fast and easy. Ball pocket provides tight fit with less rattle. Pair with existing outer tube for a secure, easy-to-use gooseneck coupler.


Features:

  • Sturdy, short inner tube pairs with existing outer tube to create adjustable gooseneck coupler
  • Oversize funnel makes it easy to guide ball into socket
    • Bottom locking plate is 50 percent larger than competition
    • Coupler engages even if you miss the ball by just over an inch
  • Tight ball fit helps to reduce jarring and rattling
    • Ball pocket provides contact on both sides of ball
  • One-handed operation with easy-to-use handle
    • Lockable with padlock (sold separately)
    • Oil-impregnated bushings increase life of locking mechanism
  • Smooth operation over time
    • Integrated grease fittings throughout make for simple maintenance
  • Superior, high-strength steel construction


Specs:

  • Ball size: 2-5/16"
  • Tube outer width: 4"
  • Range of vertical adjustment (when used with outer tube): 8"
  • Overall length: 22-1/2"
  • Weight capacity: 25,000 lbs
  • Vertical load limit: 7,500 lbs
  • Theft-deterrent locking hole diameter: 5/16"
  • Limited 5-year warranty


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.

Video Transcript for Bulldog Gooseneck Trailer Coupler - Coupler with Inner Tube Only - BD1289210300 Review

Speaker 1: Today we're taking a look at the Bulldog BX1 Gooseneck Coupler Inner Tube. This sturdy, short inner tube pairs with an existing outer tube to create an adjustable gooseneck coupler. This is designed to work with a 2 and 5/16 inch hitch ball, so if I flip this over, you can see right here, this is a slot of the 2 and 5/16 inch hitch ball.Now, one of the neat features I want to point out about this is that it uses an oversize funnel which makes it easy to guide the ball into the socket so the bottom locking plate is about 50% larger when compared to other brands, and this coupler is designed to engage even if you miss the ball by just over an inch. That is a really, really nice design of the unit. To open it up, you simply rotate the handle, slide the plate over, and move it into an open position. Now you can easily get connected, and then a locked or closed position, move the handle, slide the plate back over, and that's all there is to it.It's really nice and easy to use.

The weight capacity is 25,000 pounds, and the vertical load limit is 7,500 pounds. The tight ball fit really helps to reduce jarring and rattling, and that ball pocket provides contact on both sides of the ball.Nice one-hand operation with the easy to use handle. Right here you'll notice that it is lockable with a pad lock so that way you can secure it in the closed position. Padlock's not included. If you're in need of one, you can find some options here at etrailer.com.

That theft deterrent lock hold diameter is 5/16 of an inch, so I would recommend using a padlock with a shackle diameter of 5/16 of an inch, or even a 1/4 inch shackle diameter would work well.Smooth operation. It does have a grease zerk, so if you ever notice that it gets tough or maybe there's a little bit of resistance, you can simply just add in some grease. You attach a grease gun to that. Pump in the grease. That's going to lubricate those internal components and those moving components, and it's going to make for simple maintenance and smooth operation over time.We're looking at a superior, high-strength steel construction.

Can be primed and painted to match your trailer if desired. The tube right here has an outer width measurement, so from outer edge to outer edge is 4 inches, and that's a square design. So four by four.You'll notice that it does come with a new bolt and lock nut. So new hardware is included to get it attached to an outer tube. And you'll also notice that there's four adjustment holes on the unit, and these holes are separated on center by 2 and 5/8 of an inch, which gives you a range of vertical adjustment, when you use with an outer tube, of right around 8 inches.A few other measurements I want to go over with you real quick.

I took a length measurement from basically the top of this plate right here to the top of the tube. Length is about 22.5 inches, and the overall length measurement, from the bottom of the unit which is equivalent to the top of my table to the top of the tube, is about 24 inches.That's going to do it for today's look at the Bulldog BX1 Gooseneck Coupler Inner Tube.

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

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

This is a well made product that fits and works as billed. I added a coat of paint to match my trailer, did the installation and have pulled that trailer 10,000 miles since. Be sure to lubricate the locking mechanism well and regularly to prevent it from being very difficult to use. 611246

The BulldogBX1 gooseneck coupler was sent to me in a very timely manner and is very well built the mearsurements were perfect and is a perfect fit. Installation was a breeze. I am converting from fifth wheel to this bulldog gooseneck coupler.This product is being used on our 42ft. homemade triple axle Toyhauler our total weight will be around 20,000 lbs. We take our ATVing very seriously LOL ! Can't wait to take it out on our next outing. We have been using etrailer for quite some time now and the personnel at etrailer has always been fantastic.

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! 601291

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

This gooseneck hitch is exactly what I was looking for. It fit right into the existing neck on my horse trailer. The latching mechanism is great! I can now hook and unhook my trailer by reaching into the bed without having to actually climb up onto the truck. 378490

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

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.

Installed on a 20' gooseneck, the old one would not latch without beating it closed. The new one was installed by a local welding shop, works perfectly, simply pull the locking mechanism out slide it to the rear and the lock is engaged, just as easy to disconnect 572934

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


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

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


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.

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. 544407

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

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

Purchased this replacement for the original coupler. I had to cut the tube to the correct length on my older enclosed Featherlite gooseneck. The coupling operation is easier and I love the beveled/centering coupler which makes it much easier to center the ball while lowering the trailer. Excellent newer designed product from Bull Dog! 646383
