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

Hitch is very handy in the bottom is concaved to help ball glide into center of hitch. Easy lock and unlock of hitch. Only negative issue was it taking 2-1/2 weeks to get it. 479767

Needed a gooseneck inner tube because the trailer I purchased had a 5th wheel setup. I removed the inner tube for the 5th wheel and installed the gooseneck inner tube. Everything worked very well. Thanks. 393008

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

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

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.

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

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

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

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

The hitch seems to work ok, but a little difficult to close onto ball. It has a little more room to rotate. Ordered Friday night and received Wednesday. 237786

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

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

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

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. 633847

Great product. I bought and installed this hitch 1 year ago and have had zero problems. I did not use the outside tube portion for my set up, instead I welded the inside portion directly to my trailer as I did not require an adjustable set up. I personally am very happy with the latch mechanism. Quick and easy to hookup. 625649

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
