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.

Fast shipping. Wish tube was a little longer but otherwise great. I had to drill out holes to a larger size for my pin on my trailer, this metal is heavy. Took awhile with the wrong tools to get the job done. Bought because of the ease of the hitch and believe me it didn't let me down. I would like to be able to purchase just the hitch for replacements on my other gooseneck trailers. By far the best hitch I have on any of my trailers. Haven't had a load on it to see how it does but have hooked it up and drove around to check if it would do ok. I replaced a old sloppy wore out hitch with this one and I assure you it will not be the last one I buy. Service has been tops with this company and feel very comfortable buying from them. This was my first time going through them as I try and buy local. I just couldn't get this hitch off my mind. They keep you updated all the way from start to delivery. I loved how it shows who is actually hands on doing tasks, very personal. I felt as if I were a customer who spends thousands a month with this company and it was only my first time. I would give more stars buy only have 5 to choose. This place is a 10 out of 10 in my book, thank you for being such a great company to do business with.

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!!



by:

Great delivery....a little worried that the bottom locking plate seems thin around where the ball gets locked in? Worried that might lead to cracking....also the welding bead around the bottom head does go all the way around. Why they would leave a one inch gap is beyond me. Otherwise this is thick metal 1/4 inch and seems sturdy...good product overall!!



by:

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...'



by:

Delivery time was great! It was a pleasure dealing with very professional people



by:

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.



by:

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.

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.

Pretty good product, dimensions are as described. I bought it for the low profile, it will let us get a few more inches of height out of our gooseneck connection. Shipped and delivered on time, which is always appreciated. Be aware, this is shipped unpainted. I will spray paint mine to keep it from rusting. Haven't put it into use yet, I will update my review when I put it on the gooseneck.



by:

Hitch fit excellent but the latch mechanism had to be shimmed to get it to properly tighten against the ball. After I made and installed the shims it works great and trailer pulls much smoother.



by:

Really like this unit, it was not difficult to install, it was a direct replacement for our 30 year old stock trailer, and it is so easy to use my wife agrees this was a best buy for us.



by:

I ordered this hitch tube on Monday and it arrived on Friday of the same week
I was amazed at the very quick turn around. When it arrived I found that it was heavier duty than the one I replaced. Ian completely satisfied with etrailer and the part they sent.



by:

Everything was handled very well. Very happy customer.



by:

Got just what is ordered, A bit spectical about the Cast locking mechanism, concerned with durability. Like the concave bottom for the dummies that can't back up right.
