great product recommend to anyone needing a goose neck coupler easy to center easy to lock and to unlock from towing vehicle ball i use on a bw hitch so this coupler raises high enough to connect on a higher ball

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.

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.


Comments
Coupler is still working great. Has some surface rust around the latch area since I did not paint it there. All and all still works good as new.

I needed this to get the goose lower on my lifted flat bed. My old tube had a partial double collar and could not get it any lower. This fit, has a great latch and no double collar. It arrived covered in surface rust, wish they came at least metal etched primed. Fast shipping as always from etrailer! Thanks!!

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

It’s been working great and have zero complaints.

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.

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.

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!



- BD1289050300

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.

Works good and helped level out the trailer on my lower setting truck.

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


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.

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!

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.



- BD1289050300

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.

etrailer had exactly what I needed and at a good price.

Wish this coupler had come on the trailer when it was built. It is easy to hook up and lock. Really like the grease fitting, it keep the coupler loose and also keeps the ball lubricated.

Bought as a replacement and it fit just as good as original. The new style latch is far better than original. Fast shipping and great pricing

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!

Great service. Arrived in 3 days with free shipping. Best price online. Works great needed to shorten the nose on the trailer to hook up to a high mounted dump body goose neck. Just the ticket. Gained about 5 or 6 inches from the standard coupler.

Pat C helped me out with questions on the hitch and she was great, even went so far as to bring other people in to provide help during the phone call.

Worked great! Replaced factory coupler on PJ goose. This set 6 in lower which was perfect height for my Dodge Ram 2500 4x4.

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.

Great product and service. Do you have any Bulldog stickers? That would look great on my trailer.
