Fantastic company to deal with, which is rare anymore. I am a welder/fabricator and needed this for a job. Fast shipping, I couldn't believe it. Heavy stuff and it showed up fast- I ordered on a Friday, they shipped out the next day and it showed up to my very rural address the following Tuesday. Their website is clear and information is easy to find. I am very happy with them, the things I ordered, and will be using them in the future. Thanks etrailer!

The quality of this component compared to what the trailer manufacturer used is much higher. I would recommend etrailer for any of your needs above all other suppliers any day. Plus the price was great.

This was a great quality piece and has by far been much better than the original one that came on the trailer

@Ronald Glad we had not just a replacement for you, but a better replacement Ronald! What kind of Gooseneck trailer are you hauling around?
by:
It's a great starting point for my extreme goosenecks I weld the reinforcement ring top and bottom and reinforce the latch mechanism which makes them just about indestructible . This is the six one that I've installed they get horribly mistreated and are all working fine

@DavisF Glad to hear it's still working out well for you! If any of that paint starts to fade enough that you have bare metal exposed be sure to cover it with more spray paint to avoid rust taking hold and taking over!
by:
Good quality and stout although, the collar that assists in strengthening lower part of the tube was only welded in three small places around the top and bottom of the collar. I thought it necessary to be welded all the way around so I welded around the complete collar.
by:
I have used this coupler many times the last three have come in awful the bottom plate was not indexed correctly which makes the bottom hole useless. The bottom plate was missing 1/3 of the weld but the drain hole was welded over sharp edges everywhere there was a cut . Ram Trailer products does not take phone calls one email was returned to me it only said try flipping the pin
by:
This is the OEM coupler and outer tube on my new flatbed trailer. I ordered the trailer with the kingpin inner tube. I decided to use a goosenck hitch plate on my fifth wheel rails and this gooseneck coupler during the winter and to have in case a friend needs to use my trailer and doesn’t have a fifth wheel hitch.

I didn’t need the outer tube, but I now have spare set screws, jam nuts and load bearing pin. This was less than some inner tube-only prices.

Only reason I didn’t give five stars is because of the weld splatter that needs to be cleaned up before painting.
by:
Product looks great, haven't welded it up yet but showed up in a very timely fashion
by:
Solid product and delivered on time!
by:
I have not installed it yet but it appears to be well made but a little cleaning of the weld would have been appreciated

Excellent Product. IT was exactly what I wanted. Shipped very fast. This time I had a great experience with ETrailer
by:
The salesmen at E-trailer were very helpful. I didn't get original part that I ordered as it was back ordered but found me a satisfactory alternative. I'd order again from E-trailer
by:
Great Customer service and the delivery time was very expeditious. It came 3 days earlier than expected. The coupler is very well structured and put together with a good grade of steel. Couldn’t be more happier with it.
by:
This product worked great for me.
I will
continue to purchase from e trailer, like doing business with them.
by:
It's perfect. It took us a while to get someone to put weld it on but it's fantastic!
by:
Quality and workmanship look and seem extraordinary. I can give you an overall assessment in 40 yr., but I think it will outlive me.

  • How to Use the Ram Gooseneck Coupler Part # GCPN-30008
    The Ram Gooseneck Coupler part # GCPN-30008 gets welded on the trailer and then attaches to the gooseneck hitch ball in the bed of your 2017 Ram 3500. You will want to use the adjustment holes on the coupler to try and get the trailer as level to the tow vehicle as possible. Once this is done you can then pull the spring pin on the coupler to secure it to the hitch ball in the bed. After the coupler is securely seated on the hitch ball you can then attach the safety chains and wiring. Then...
