could not b any easier, a great place to shop



by:

Great price works well



by:

Perfectly as described and manufactured well.
only reason i give 4 stars instead of 5 is the box it came in is trashed and almost falling out of the box.
it needs packaged to take the abuse along the way.



by:

Very well built, will send pictures as soon as installed, great service, overall excellent. Thanks



by:

great customer service



by:

The Price was good, but the quality control could be better, some of the welds are very poor. I'll be re-welding these in a few places, mainly the reinforcing strap around the bottom of the outer tube and the locking bolt bung. Other than the poor welds, this is a solid coupler.

Oh no, I am sorry that you have received the product in such a manner. I have sent this over to our quality control department to check on the rest of our stock for these welds. We strongly advise in the future that you reach out to customer service to see if they can help before repairing the welds on your own. Our warranty will not cover products once they have had modifications performed on them as we cannot guarantee your safety.



by:

Great pricing Fast shipping.

Packaging is poor welds need to be grou nd

Item was described exactly as advertised and shipping was right on time.



by:

The ease of ordering, price, speed of shipping, and quality of product were all Excellent! Thank You! You are now on my list of suppliers



by:

The weld quality on this gooseneck coupler is horrible! Our fab shop will have to repair almost every weld on the coupler. For something that is supposed to be rated for 30K pounds I'd expect a certified welder to weld the coupler. But this is not the case because the undercut and lack of fusion on this coupler would not be present if a certified welder welded this coupler. Also, it came as bare metal not painted as shown in the picture. We are NOT satisfied at all with this product!



by:

unfortunately the handle did not make it.
the
handle is not even installed correctly, it is missing the Carter pants to hold it on.
it is only being held on with shrink wrap.
this tells me very possibly it was broken before it was shipped.

this is not like etrailer what the heck.

can you please send me a replacement handle.

Thanks,

The shipping was great, I didn't expect it that quick. It is the same that was originally on the trailer, great fit. Thank you.



by:

Excellent product! Fast delivery! Would buy again

makes it much easier to hook up tailer with wider opening on bottom.

Looks awesome, Ron! What type of trailer is that on? I can't quite tell from the photos. [Which, by the way, thank you for sharing :)]



by:

I am quite surprised that it wasn't painted at all.
Rust showing in many places so get brush to remove rust and then get primer and paint.
A few weld sprays to clean up.

All else is very good and well built.
Packing for shipping is very good.
Promise delivery date was very good.



by:

It worked great and it was perfect fit



by:

Great product worked great but parts missing broken box



by:

Fast shipping and exactly what we needed



by:

The new topwind coupler didnt not come with grease in the top bearing. And I installed a rubber washer to help keep the water out of the new one. How does this not get mentioned that it must be disassembled and greased before instalation



by:

Fit up was great and efficient to make height adjustments for different trucks. I’m buying another for my stock trailer.

  • Can I Take the Inner Tube of the Ram Gooseneck # GCSQTW-30008 and Put it in My Outer Tube on Trailer
    Hello Jerry, Great question. It all depends on on if it is compatible. If your current set up is not a topwind coupler then it isn't going to work because the # GCSQTW-30008 does not use traditional pin-adjustment holes (please refer to picture I attached) like other gooseneck couplers. Instead, it relies on the spinner nut mechanism at the top to secure and adjust the height of the inner tube. If you find that it is not compatible please let me know so I can have someone from customer...

  • Is it Normal for There to be Play in Gooseneck Coupler Side to Side
    Hey Weston, gooseneck couplers aren't super refined and since they are also adjustable it's not unheard of for there to be some play due to looser tolerances. Now I don't know what specific coupler you have but as long as the bolts are tight and there's nothing else you can see that's worn out you are probably just fine.

  • Replacement Gooseneck Coupler Similar To The 30K Bulldog BD028900
    Hi Oliver! What you are looking for is the Ram Gooseneck Coupler - Topwind - 7" Adjustment - Square - 2-5/16" Ball - 30K # GCSQTW-30008. This is nearly identical to the Bulldog Gooseneck Coupler BD028900 you currently have on your trailer. The only real differences between them is the vertical adjustment height on the Ram is 6", whereas the Bulldog is 7", and the fully extended height on the Ram is 38" whereas the Bulldog is 39". Other than that, they would be hard to tell apart. It's...

  • Will the Ram Topwing Gooseneck Coupler Inner Tube Work With Another Coupler
    The Gooseneck Trailer Coupler part # LL2516ST and Ram Gooseneck Coupler part # GCSQTW-30008 both have a 4" wide inner tube with similar topwind handle. Therefore, in theory you should be able to swap the inner tube out between one another. That said, there is no way to confirm this as there are more moving parts than just the handle and inner tube and since they are different manufactures one could have used different components that the other making the two incompatible. I spoke with RAM...

  • Recommended Coupler Lock for Big Tex Gooseneck Trailer
    I was not able to locate specific manufacturer information regarding the couplers that are used on Big Tex Gooseneck Trailers like what you have. With that being said, they do look very similar to the Ram Gooseneck Coupler # GCSQTW-30008 that you mentioned, with its square tube design and crank. If you find that this is what you have, I recommend the Blaylock EZ Lock Gooseneck Coupler Lock # BLTL-55-40D. This coupler lock is designed specifically for Ram gooseneck couplers and features...

  • Recommended Heavy Duty Gooseneck Coupler For Clearance and Adjustability
    It sounds like you want vertical adjustability for 30K gooseneck coupler. It appears you may be seeking 30 inches of vertical travel and we don't have anything with that capacity. The normal range is 7-8 inches but the retracted heights can vary. We have the following options for you: Bulldog Gooseneck Coupler- Round - 30,000 lbs # BD0289500300 with 8 inches vertical travel with a retracted height of 29-1/3 inches.

  • Replacement Adjustment Handle for Ram Adjustable Gooseneck Coupler GCSQTW-30008
    If the coupler will not adjust be sure that the set screw (shown in the linked photo) has been loosened to allow the coupler to move. If the set screw has been loosened and the unit will not adjust try applying a product like PB Blaster or WD40 to the set screw hole with the unit upside down so that it can flow down into the mechanism. This might help loosen up the adjustment function. If you need just a Replacement Topwind handle assembly for your Ram Adjustable Gooseneck Coupler # GCSQTW-30008...

  • 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...

  • Does Ram Gooseneck Coupler # GCSQTW-30008 Weld to Trailer
    Yes, the outer tube of the Ram Gooseneck Coupler # GCSQTW-30008 that you referenced is designed to weld to the front of a trailer. Every gooseneck coupler like this would require welding so there isn't a bolt-on solution I could recommend instead of this. I attached a review video for more info on this for you to check out as well.
