Was a great investment easy to install worked well for what I needed couldn’t beat the price

It is a great replacement for a worn out coupler on my 14,000 pound gooseneck flatbed. fit perfectly in the receiver tube and seems to be functioning as it should. I would definitely purchase again.
by:
Fast and reasonable price. Fit as it should good quality !
by:
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.

After a year, this coupler still works as good as new.

by:
It came very quick and was what we ordered
by:
I think you should add spot for pickup at your store
by:
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.

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.

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

by:
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.
by:
I have a gooseneck trailer that I need the option to switch between a kingpin and ball set up do to the different trucks that pull the trailer. Swapping out the couplers is the easiest fix and this coupler works great. All I did was paint it to match the trailer.
by:
Very good quality of a commercial grade.
by:
It was a great change over, don't have to climb in a release the lock this one opens and closes on it's own.

Fast shipping, good price, and a real quality coupler.
Can’t wait to get it installed.

Works great! I wish they made them so you could just throw a pad lock on them when they are not in use. I wish I would have thought of that when I was building my trailer, would have been so easy to do.

by:
Product was works great was just as it was advertise. etrailer was honest in their dealings and had over charged for shipping. The people caught the error and corrected it to my favor. Will do business with them again. Good product & honesty do not fine that every often in our whole today!
by:
Haven’t installed the coupler yet, have to clean up a couple welds that went too far into the area where the ball goes then paint. Test fit into existing tube on trailer showed it was a little loose, not a big deal as it is tighter in the tube it came with. Overall happy with the hitch and price point.
by:
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.
by:
very satisfied with order-fast shipping-very well built product-changing a 5th wheel camper hitch to a gooseneck set up-will share pics when complete
by:
The box was ripped open when I received it, but everything inside looks fine. Looks like a very nice and sturdy gooseneck hitch.
by:
Great product, great price. Made my much needed trailer repair a breeze.
by:
Looks nice and heavy duty, just what I needed to replace the coupler o my gooseneck
by:
The part I originally ordered was on back order for a month.
I was called by Etrailer about the problem and we found a comparable part and I had it within two days.
Not many companies will call you about a back ordered part they usually just let you wait.

Do you have a question about this Gooseneck Coupler?
  • Gooseneck Replacement Coupler Options with a 4-1/2" Outer Diameter
    Hey Jay, thanks for reaching out! We have the Ram Gooseneck Coupler w/ Load Bearing Pin # GCPN-25008 which is a round option or the Ram Gooseneck Coupler w/ Load Bearing Pin # GCSQ-25008 which is a square option. Both come with the inner tube as well as an outer tube with a 4-1/2" outer diameter so you just need to choose the correct style. If you're looking for an inner tube that has a 4-1/2" diameter than you're looking to make a custom order to one of the gooseneck coupler manufacturers...

  • What Size are the Set Screws on Ram Gooseneck Trailer Coupler # GCPN-25008
    Ram gooseneck coupler # GCPN-25008 has set screws and a 7/8" diameter pin. The set screws are 3/4"-10 x 2-1/2". It is recommended to use a large crescent wrench to adjust the set screws since they have a square head instead of a hex head like a regular bolt. There is a replacement set available as # SS-34103-BT. The matching set screw nuts are # SS-34103-NT.

  • Does The etrailer Gooseneck Coupler Head Kit Fit a 4 Inch Gooseneck Coupler Inner Tube
    Yes, the Gooseneck Coupler Head Kit part # GC-HEAD replaces the coupler head on etrailer.com or Ram, round and square Gooseneck couplers. It is designed for use with GCPN Series, GCSQ Series, and GCSQTW Series couplers which all have the 4" inner diameter tube and 4-1/2" diameter outer tube. I have attached a photo of the coupler head installed on Ram Round Gooseneck Coupler part # GCPN-25008 for your reference.

  • Wall Thickness Of Outer Tube On Ram Gooseneck Coupler
    The Ram Gooseneck Coupler w/ Load Bearing Pin - 8" Adjustment - Round - 2-5/16" Ball - 25K # GCPN-25008 has a wall thickness of 0.21 inches on the outer tube. The inner tube has a wall thickness of 0.24 inches. I reached out to the manufacturer to get these precise measurements for you.

  • 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 to...

  • How Much Clearance is Needed Between Gooseneck Trailer Overhang and Bed Rails
    You want at least 6 inches between the overhang of your gooseneck trailer and the bed rails of your truck. Thanks for sending in a picture of your tow setup. You definitely need to get the nose of the trailer down so that it can be level.

  • Recommendations For Locking A Gooseneck Trailer Coupler
    Though it will ultimately depend on the style of your coupler, we do have a few options available for you to check out. First is the Blaylock EZ Lock Gooseneck Coupler Lock Combo # BLTL-57-40D2. This includes a lock for your coupler as well as for the set screw that holds the coupler in the frame tube. This will fit most adjustable RAM gooseneck couplers, like the # GCPN-25008, but it is kind of limited to that. This is a very common and popular style though, so it may be right for you. If...

  • Replacement Gooseneck Coupler Solution for Trailer with Outer Tube Less than 4 inch Diameter
    I have an option for you but since your outer tube is less than 4 inches in diameter we don't have an inner tube that's going to fit. Best option would be to remove the outer tube and weld on something like the Ram Gooseneck Coupler part # GCPN-25008.

  • Recommended 5th Wheel Adapter for Round 25K Ram Gooseneck Coupler
    Yes, you can use the Gooseneck to 5th Wheel Trailer Coupler Adapter part # KPG5-R25-IP to convert the Ram Gooseneck Coupler part # GCPN-25008 from a gooseneck to a fifth wheel attachment. In order to do this you'd simply remove the gooseneck inner tube from the old coupler and replace it with the fifth wheel inner tube.

  • 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.

  • Lock for Ram Gooseneck Coupler With Round Tube
    The InfiniteRule Hitch Lock is designed for goosenecks with a 4" round outer tube, and the RAM goosenecks have a 4-1/2" round outer tube like the Ram Gooseneck Coupler # GCPN-25008. For the most security I recommend the Blaylock EZ Lock Gooseneck Coupler Lock Combo - RAM Gooseneck Couplers # BLTL-57-40D2. This has a coupler latch lock and set screw lock and comes with a pair of padlocks for the best way to secure your gooseneck. You also have the option of getting the coupler lock...
