Slid into the trailer perfectly. Was a little long so I cut off 5” but it’s better than being short. The dished inside of the coupler makes lining up over the ball so much easier since it only has to be close now instead of almost perfectly over the ball.

Very nice coupler. I did not know these existed. I have used the old lift pin, hammer the latch and lock the pin style thinking there was no other way to hitch up a gooseneck. I purchased a used trailer and found out the coupler was blown out. Searched to find a replacement. Found once again that e-trailer was superior in price and selection to anywhere else in the world. I found my old standard style coupler but also saw this comparable item. For $20 more than the standard coupler I could have one that latches itself when set on the ball. No brainer. I asked my 10 year old son which one he would get and he did not hesitate in selecting this one. After my purchase, I found an ad for a brand new trailer like mine that listed as a selling point it had this same coupler. I installed it and used it once so far. It worked flawlessly as the e-trailer video suggested it would. On a side note, in the past it seemed I always had to pay shipping at e-trailer but with this order I did not. That was greatly appreciated also. Even more value working with e-trailer. I couldn’t be happier with this purchase.

Glad you and your son found it, Dennis! These have only been out for about a year now and they are really starting to gain in popularity. Demco's eZ-Latch has been my preferred style for standard trailer couplers and I was pretty stoked when I heard they were going to integrate it into a gooseneck coupler. What kind of trailer did you install it on?

@LazerS PJ 30 foot flatbed tandem with duals. I believe it has a 25,000 lb gvwr. The old coupler was rated for 25,000 lbs but obviously failed. This one is rated for 30,000 lbs I believe.

@Dennis It is indeed rated for 30K, so it should last you a good long time. What do you typically tow on your PJ trailer?

@LazerS I just purchased it used and the last owner hauled some pretty heavy tractors which I think is what caused the old one to fail. I’m planning on hauling a larger sized skidsteer and attachments mainly but hoping to haul some scrap iron and random farm machinery.

Item as described, good quality, heavy build, looks great and works great.
by:
The product itself is great. But when replacing the round tube gooseneck couplers. The holes do not line up. So your latch is not straight. Just need to give the holes a slight angle. As one of your competitor offers. I purchased 3 of these, at the same time, not knowing. So either return or just deal with the latch not straight. Hope that helps others.

See what our Experts say about this Demco Gooseneck Coupler

Do you have a question about this Gooseneck Coupler?
  • What is Widest Point of Demco EZ Latch Gooseneck Coupler
    Hey Hieu, the overall width of the Demco EZ Latch Coupler part # DM73KV that you referenced is 7 inches at its widest point. That's a good eye on the hole orientation! The actual orientation is 120 degrees out from the latch of the coupler. The product pictures show an early model/sample we got that we took pictures of and it looks like they moved the holes by the time they put it into production.

  • Can I Use the Demco eZ-Latch Gooseneck Coupler on My Texas Pride Gooseneck Trailer?
    Hello Danny, Does that mean that your trailer is bigger than all the others, just like everything else in Texas..... bad joke, I know. I have not heard of any issues with the Texas Pride and not being able to use the Demco eZ-Latch Gooseneck Coupler # DM73KV, so I went ahead and reached out to our tech friend and Demco to see if he had heard of any issues, and he has not either. In order to know if it is really going to work or not, you will need to get a caliper and measure the OD...

  • What Direction Should Demco eZ-Latch Gooseneck Coupler Latch Face
    Hi Dennis; the Demco eZ-Latch Gooseneck Coupler # DM73KV can face any direction as long as the holes line up. If you think it will work best facing the rear I would install it that way. Worst case, if it doesn't work as well as you want it to you can flip it around to face the front.

  • Will The Demco Lock DM88KV Fit My PJ Trailer With a Demco EZ Latch Coupler
    Hey, Johnny! The Demco gooseneck coupler lock part # DM88KV will definitely work for your PJ gooseneck trailer. As long as it has the Demco EZ latch. The lock specifically designed for their EZ Latch gooseneck couplers that are rated for 30k. I believe all of their gooseneck couplers are rated for 30k like part # DM73KV so you should have no issues with fitment.

  • Recommended Lock for the Demco eZ-Latch Gooseneck Coupler Adapter
    Hey Connor, there is no integrated lock for the Demco eZ-Latch Gooseneck Coupler # DM73KV but you can use the InfiniteRule Lock for Demco eZ-Latch Trailer Couplers # IR66FR to lock it, no Gooseneck coupler lock necessary. What kind of trailer do you have? If you have any other questions, please feel free to drop a comment and let me know!

  • Recommended Demco eZ-Latch Gooseneck Coupler DM73KV
    Hey Mark. The Demco eZ-Latch Gooseneck Coupler item # DM73KV will only work on your 2004 Elite 2-horse gooseneck trailer if it has straight pin holes. It will not properly align with angled pin holes. This is a 4" round inner gooseneck tube that has four adjustment pin holes with a 13/16" diameter spaced 2-3/4" apart. There's no database that shows me what kind of gooseneck tube, bolt pattern, or angle of the holes and Elite's website doesn't go that far back so you'll need to take a look...

  • Replacement Inner Tube Gooseneck Coupler 4" Diameter For BullDog Bx1 25k
    Hey there John, I can help you out with this. While we don't have the specific Bulldog inner tube for the Bulldog BX1 Gooseneck Coupler - Adjustable Height - Round - 2-5/16" Ball - 25,000 lbs # BD1289000300, but Bulldog carries it under part number 1289020300. I'm working on getting it added to our site for you, but it may take a few days. That said, this is a pretty standard size (4" inner tube) so you can pair it up with a different brand inner tube like the Demco eZ-Latch Gooseneck...
