Looks like a hoss! Just based off seeing the fenced in space in the pictures, do you travel with horses?

by:
This hitch was very poorly made. I had to redo every weld and I only kept it because I was in a bind. I should’ve taken before and after photos.

Super great love it

by:
Welded right on perfect! Very happy!
by:
Everything worked as expected. Would definitely by again.
by:
It was perfect and fast shipping
by:
Some of the welds looked a little rough and there was quite a bit of spatter on the tube, but with that said, there's no way you'll find a better value for the money. Since I had to weld the hitch on anyways, I cleaned the spatter off with a flap wheel and went over the welds I wasn't happy with. I wouldn't hesitate to purchase another one.
by:
Great service and fast shipping. My first stop for trailer parts for sure. Thank you
by:
Worked great on a gooseneck restoration project for us. No issues to date with several trips on the trailer.
by:
Just what I needed to convert my 5th wheel rv to a gooseneck.
by:
It was the exact replacement I needed....it arrived in a few days and was just installed. I like that it is adjustable and has a way to lock it into position.

Thanks etrailer.
by:

Do you have a question about this Gooseneck Coupler?
  • Gooseneck Coupler to Convert Trailer Back to Gooseneck From Bumper Pull
    Hi Gerry; they're both going to do the same thing so I would stick with the square # GCSQ-25008 since that is what it looks like it originally had.

  • 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...

  • Replacement Gooseneck Coupler Options for Big Tex Trailer with 3-1/2" Square Coupler
    I do have an option for you but we don't offer any inner tube square gooseneck couplers which measure 3-1/2" x 3-1/2" as this is not a standard size. That said, what you can do is install a new outer tube and inner tube of the standard size 4" x 4" to upgrade the coupler. I recommend the Ram Gooseneck Coupler part # GCSQ-25008 which has a 25,000 lb rating.

  • Replacement Gooseneck Coupler Recommendation for Setup that Uses 3.5 inch Inner Tube
    The only solution we'd have would be an all new outer and inner coupler like the Ram Gooseneck Couple part # GCSQ-25008 as we don't have anything that is designed for a 3-1/2 inch square inner tube. Everything we offer is for 4 inch square tube.

  • Weld-On Square Gooseneck Trailer Coupler
    We do have weld-on gooseneck trailer couplers that are 4-1/2 inches square, they are complete couplers as I'm not 100 percent certain what you are referring to by changing the coupler at the base, unless you mean welding it on. For a weld-on gooseneck you can use either of the following: - Ram Gooseneck Coupler - 7" Adjustment - Square - 2-5/16" Ball - 30K # GCSQTW-30008 - Ram Gooseneck Coupler - 8" Adjustment - Square - 2-5/16" Ball - 25K # GCSQ-25008 I have added links below to video...

  • Installation Orientation of Ram Gooseneck Coupler with Square Tube
    When installing the Ram Gooseneck Coupler w/ Load Bearing Pin - 8" Adjustment - Square - 2-5/16" Ball - 25K # GCSQ-25008 or any square tube coupler, usually the outer tube is welded on so that the set screws face forward, which puts the latch at a 45 degree angle forward of the drivers side

  • Is There a 3-D Drawing of Ram Gooseneck Coupler Load Bearing Pin - 8" Adjustment - Square - 2-5/16
    In regards to the Ram Gooseneck Coupler part # GCSQ-25008, the main things you need to know are the size and weight capacity. The outer tube which gets welded to the tongue of the trailer is 4-1/2" x 4-1/2". The inner tube which is what slides in and out of the outer tube to adjust height and houses the coupler, measures 4" x 4". The weight capacity is 25,000 lbs. I have also attached for you below a few other dimensions you may find useful. Ball size: 2-5/16" Range of vertical adjustment:...

  • Can New Holes Be Drilled for Ram Gooseneck Coupler Inner Tube
    Thanks or reaching out, Paul! If you want the handle for the Ram Gooseneck Coupler w/ Load Bearing Pin # GCSQ-25008 to be forward-facing then you'll want to weld it on in that orientation. If you were to drill a whole new set of holes in the inner tube that would make the inner tube weaker and we'll want to avoid that.

  • Availability of Replacement Gooseneck Inner Tube Coupler with 4-1/2 Diameter
    The only replacement gooseneck coupler inner tube that we carry which has the 4-1/2" outside tube measurement is the Bulldog Gooseneck Coupler # BD0287690300. This is a round coupler that has a weight rating of 20,000 lbs and fits over a 2-5/16" hitch ball. If instead you have a square coupler the only option we have to offer is an entire replacement like with th Ram # GCSQ-25008 which is rated for 25,000 lbs and a 2-5/16" hitch ball. This comes with both the inner and outer tubes which...
