Video Transcript for Bulldog Gooseneck Trailer Coupler - Coupler with Inner Tube Only - BD1289050300 Review

Today we're going to be reviewing part number Bd1289050300. This is the Bulldog BX1 Gooseneck Coupler. It is the Inner Tube. This sturdy inner tube is going to pair with the existing outer tube to create an adjustable Gooseneck coupler. It's going to feature the oversize funnel, it's going to make it easy to guide the ball into the socket. It's going to be this portion here. The bottom locking plate is 50 percent larger than competitions.

The coupler's going to engage even if you miss the ball by just over an inch. It has that nice funnel, it's going to help direct the ball into the coupler. The tight ball fit is going to help to reduce jarring and rattling. The ball pocket is going to provide contact on both sides of the ball. It's going to feature the one-hand operation so it's going to be very easy-to-use, especially using the handle. This portion is going to be lockable using a padlock.

It's going to feature the oil bushings, its going to increase the life of the locking mechanism. You can see here, by turning the handle, that's going to allow you to adjust the plate as needed. That way you can engage or disconnect the ball from the coupler. It's also going to provide smooth operation over time. It's got the integrated grease fittings throughout that are going to make for simple maintenance. It's got the superior, unfinished high-strength steel construction so it's going to provide a really long life. It is designed to fit a 2-5/16" ball.

The tube diameter measuring the outside to outside is going to give us a measurement of 4". The range of vertical adjustment when used with the outer tube is going to be 8". If you need the outer tube, you can find that here at etrailer.com using part number Bd0289500300. It's going to give us an overall length of 22", with a weight capacity of 30,000 lbs. It also has the zert fitting right here, that way you can get the grease as needed. Again, easy maintenance and it's going to provide a really long life.

It's going to come with a pin and clip. The clip is attached to the pin with a cable, that way you don't ever have to worry about misplacing it or losing it. Then again, you have the adjustment holes as well, allowing for 8" vertical adjustment when used with the outer tube. That's going to do it for today's review of part number Bd1289050300. This is the Bulldog BX1 Gooseneck Coupler. .

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



- BD1289050300
by:

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

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

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 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



- BD1289050300

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

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

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 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

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

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 love it. Lots easier to hook up. If I buy another trailer I will change it to this hitch!

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

Ive ran the BX1 on my stock trailer around a year now, works great perfect tight fit. Convenient lock system and love the tapered bottom, as long as the ball is within a couple inces it slips right into place. Would definatly buy another! 331716



- BD1289050300
by:

This coupler is awesome! The couple is easier to back under and latch than any other coupler I have ever seen. I've been meaning to order another one and I'm ordering today. The BEST! 315510



- BD1289050300
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! 314866

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
