Video Transcript for etrailer.com Ram Gooseneck Coupler Review

Hey guys. Randy here at etrailer.com. Today we're taking a look at our two and five sixteenths inch gooseneck coupler. Now this coupler is going to be pretty ideal for most gooseneck applications. It's a little bit heavier duty here at the bottom. Sometimes I like gives you a lot of confidence in it.

Another nice feature is that it's got the spring loaded release here at the bottom, so we pull that up and turn it and as we lower this down on our ball, it's automatically in a open. Then close behind it. At that point, all we have to do is pull our handle. You see it clicks right down in position. You can see our base plate here is going to be much thicker than what we are used to seeing with some of the smaller types.

It's going to have a nice wide bevel on it as well, so if we're not exactly centered underneath that ball, it's going to help to guide it in as we put weight on it.All in all, it's a really nice easy to use coupler. The overall construction feels really nice. You've got heavy duty welds around here and they're really clean. You'll see a little bit of welding slag here and there on it, but it is an unfinished coupler and we're going to have to paint it anyway, so most of that's going to come off as we sand blast it before it goes through that paint process. Now as we said, this coupler is going to work on just about any gooseneck application, but it does have its kind of its sweet spot.

I think that's going to be in your farm use, in your utility use or if you just don't haul your trailer very often. If you haul a gooseneck trailer regularly, you're used to some of that chucking, bucking and noise that we get. It can make your ride a little bit uncomfortable.So if you've got horses or livestock or living quarters in a trailer that you're trying to haul with you, I'd recommend something cushion, maybe the GEN-Y or the Convert-A-Ball cushion used from that mount. Basically that cushioning is going to take the rigidity out. So the Convert-A-Ball has about three quarters of an inch of movement there.

Your GEN-Y uses a torch and flex system and it can overall just give you a better experience while hauling your gooseneck trailer. The gooseneck is going to offer us about eight inches of adjustability, so we can move this down and up eight inches. So right now we're about 11 inches, 11 and a half inches to the bottom of the coupler to our pinhole. We can get that all the way out to about 19. Alright, now we can move on to the installation process and that's really going to depend on how you're set up currently.If you are rebuilding a trailer, maybe it took damage, you need to repair it or building a new trailer, then the outer tube is going to be something that you'll want to install. Now this is a weld on outer tube, just like any other gooseneck coupler. This one uses two set bolts. The set bolt can be tightened down using a 23 millimeter 12 point and it's going to have two jam nuts. Those you're going to need an inch and an eighth for. I like that it's not painted. That's going to prevent us having to kind of, grind all the paint off to get a proper weld done on it. Standard length on these, it's about 20 inches. You're going to see that just about across the board on the coupler, outer tubes. And one thing to make note of, the top is open on these and typical applications that's going to be capped off.That prevents moisture from getting down in there, causing that inner and outer tube to kind of rust together. So I highly recommend if you are going to install the outer tube that you have that plate welded on to protect your two components from the elements. Now with us not replacing the outer tube, we're going to take our inner tube, you're going to slide that up and in. You can see the four holes here. That's where we get that eight inches of adjustment. And as we bring that in, we just line up the pinhole with the hole in the outer tube and slide the provided pin through. We're going to secure it on the other side with a clip. Now to set your coupler height appropriately, you're going to want this to be either matching to or as close as you can get it to what your old coupler was or you'll want it to be about two inches lower than what your ball sits in the back of your truck compared to the ground. And once you've got it pinned in the appropriate spot, I'm using an inch and an eighth on this particular boat. Remember, if you're using the outer tube that comes with it, it's a 12 point 23 millimeter.We'll torque that down to the appropriate specifications. Once we've got that there we're going to bring that jam nut down and we'll need to put a pretty decent amount of force on it here. Basically that's going to prevent this bolt from backing out on us. Now of course the inaudible 00:04:19 We'll want our locking pin released it, then we'll just lower it right down. You'll notice that gate is going to move out of the way as we talked about and even as we're uneven there a little bit, it guides it right down on the ball. So overall nice and easy to connect. Let's get the weight down, you'll see that plate go back forward. Then it'll just be a matter of pulling our locking pin around here, that goes down and engage. We make the rest of our connections. We'll be ready to head down the road. That's going to complete our look at our two and five sixteenths inch gooseneck coupler.

I ordered these items for my DIY project, turning my bumper pull trailer into a goosenech trailer. The parts are of good quality and the delivery was quick. I would highly recommend for anyone who needs something for a DIY project to order from ETRAILER.COM I went from that to this. 336168

- GCPN-25008

Used it on a bumper pull that I converted to gooseneck 20 foot flatbed trailer. Took a few trips of delivering equipment and vehicles to set it up the way I wanted it. Mostly I'm around 12-15k. The funnel really helps hooking up and the spring lock is great. Yes I would recommend to my best friend. Great product great service and it was packed up in the box great. 749649

- GCPN-25008

I replaced the original goose neck coupler on a my 1986 Lazy N horse trailer that didn't have an adjustment. The new hitch worked well and gives the additional clearance needed to pair an old trailer to a newer truck. This hitch will save my tailgate and bed side now. Etrailer has free fast shipping on this item and I like the fact that the receiver latch is spring loaded. Great product. 664035

- GCPN-25008

Love the features of this reasonably priced gooseneck coupler. The large cast coupler allows the trailer to be connected even if you are off a little bit on the alignment with the ball. I also like the pin for locking in the height and not relying on just the set screws. Overall, I am very impressed with it and can't wait to get it installed. 395341

Still works flawlessly after a year of use. I have it on a small gooseneck flatbed and could not be happier with it.

- GCPN-25008

Product seems to be good quality for a good price. The only thing I would suggest is better packaging for heavy items like this hitch. The coupler end of the hitch had torn a large hole in the cardboard box, but luckily the other items that were shipped with the hitch had not fallen out of the box. 308355

on time and they gave me what I wanted I will tell my friends thanks. 260341

your hitch is great

  • Replacement Gooseneck Hitch Recommendation for Hanover Trailer
    You would want to just remove the tubing and replace it with a setup that includes an inner and outer tube setup like the part # GCPN-25008. A fabricator would have no problem removing the old setup and attaching this.

  • Troubleshooting Alignment of Gooseneck Coupler with Inner Tube Replacement
    The B&W Extend-A-Goose Gooseneck Coupler - 10" Offset # BWTEXA4200 should be a straight fit. If your coupler was not installed so the pin was horizontal, then there isn't another adapter that will fit correctly. The misalignment will be an issue with any replacement. I recommend replacing your coupler with the Ram Gooseneck Coupler w/ Load Bearing Pin - 8" Adjustment - Round - 2-5/16" Ball - 25K # GCPN-25008. Your only other option is drilling a new hole in your current coupler...
