Features to know about

Self-Latching Coupler for a Secure Connection

No more struggling with your gooseneck coupler. The spring-loaded handle automatically locks onto the hitch ball, making hookup a breeze. When you're ready to disconnect, the hidden latching mechanism holds the handle open, so you don't have to wrestle with it when unhooking.

Curved Internal Ball Clamp for a Tight Fit

A loose connection can lead to excess movement and noise while towing. This coupler features a curved internal ball clamp, ensuring a strong, secure hold on the hitch ball. That means less play, better stability, and a quieter tow.

Heavy-Duty Steel for Maximum Strength

When you're hauling up to 25,000 lbs, you need a coupler that won't let you down. With a machined cast head and reinforced steel tubing, this coupler is built to withstand heavy loads and rough conditions.

Adjustable for a Level Tow

With 8" of vertical adjustability, you can fine-tune your trailer height for a level, stable tow. Whether switching between trucks or adjusting for different loads, this coupler gives you the flexibility you need.

Weld-On Installation for a Secure Fit

For a permanent, secure connection, the outer tube is designed to weld directly to your trailer frame. This ensures maximum strength and long-term reliability, so you don't have to worry about movement over time.

  • Gross towing weight: 25,000 lbs

Video Transcript for Review of etrailer Gooseneck Coupler - Gooseneck Coupler With Load Bearing Pin - e66MV

Hi, everybody. Andy here with etrailer.com. Let's take a real quick look at this etrailer gooseneck coupler with load-bearing pin. This 25K gooseneck coupler self-latches for easy hookup, while the ball clamp ensures a tight fit. The spring-loaded handle is going to automatically lock onto the 2 5/16 inch hitch ball, making hookup a breeze. When you're ready to disconnect, the hidden latching mechanism is gonna hold the handle open so you're not gonna have to wrestle with it when unhooking.

So I don't have the strength to actually show you the self-latching mechanism. I have it in the position right now, to where you could just drop this onto your 2 5/16 inch ball and it would just automatically self-latch. And then when you're ready to uncouple, when you're ready to disconnect, you'll just move that handle over like that. It'll stay in that position and then you'll be able to uncouple off of that ball. So this is going to be very easy to couple and uncouple.

So lemme just kind of tip this back a little bit. This coupler does feature a curved internal ball clamp that's going to ensure a strong, secure hold on the hitch ball. So that means less play and better stability and a quieter tow. So when you're hauling up to 25,000 pounds, you're gonna need a coupler that's not going to let you down. With the machine-cast head and reinforced seal tubing, this coupler is built to withstand heavy loads and rough conditions.

So again, the gross towing weight is going to be 25,000 pounds. This has a vertical load limit or a maximum tongue weight of 6,250 pounds. And with 8 inches of vertical adjustability, you're gonna be able to fine-tune your trailer's height for a level stable tow. So whether you're switching between trucks or you're adjusting for different loads, this coupler is going to give you the flexibility that you need. And for a permanent secure connection, this 4 1/2 inch outer tube is designed to weld directly to your trailer's frame.

That's going to ensure maximum strength and long-term reliability so you don't have to worry about movement over time. If you we inchesre just wondering about the overall height as it sits right now end to end, we are almost 29 inches tall. But I think that's gonna wrap up our real quick look today. I do hope that our brief time together was helpful for you. If you happen to have any other further questions that I didn't answer for you during our time together, don't hesitate to reach out to us and either by phone, email, or chat. We do wanna make sure that you're getting exactly what you want and need. Well, I think that's gonna wrap up our quick look today. I do hope that it was helpful for you. Again, my name is Andy, thank you for joining me.

Glad the # GCSQTW-30008 worked well for you Troy and really appreciate the photos. What are you hauling usually?

by:
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!

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

by:
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:
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.
by:
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.

I went from that to this.

Super great love it

I think you should add spot for pickup at your store
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.

  • Availability Of Gooseneck Coupler Inner Tube With 3-3/4" Outer Diameter
    Hello Heath. I do appreciate you reaching out, but I am sorry to say we do not offer a gooseneck coupler inner tube with a 3-3/4" OD. Everything we have is a standard 4" tube. Do you know the brand of your gooseneck coupler? At this point the next step would be to look at replacing the entire gooseneck coupler with a new one such as the following: - etrailer Gooseneck Coupler w/ Load Bearing Pin - 8" Adjustment - 2-5/16" Ball - 25K # e66MV
