Ball coupler is made of sturdy steel. Adjustable channel bracket is sold separately. Mounting hardware is included.


the 1st one received was stuck on the truck. TI had to really fight to get it off of there. The replacement one does the same thing but I am able to get it uncoupled. Just takes some effort to do so.


Latching mechanism is vey troublesome gets stuck on the ball


bolted right on, is rated above the trailer weight limit so I'm sure it will hold up. So far easy to hook up and unhook.


Well built heavy duty product. Will be a huge improvement over the chinese coupler that come on my new dump trailer. Also plan on installing one on my tag trailer.
Great price and also super fast shipping
I will certainly use etrailer again

Same issues as the elcheapo chinese couplers. When you have to use prybars and set the trailer brakes and rock the truck back and forth to break the couple free its a real pain. I have went back to pintle hitches.


replaced a cast coupler on a new trailer as I felt it not safe to pull a 22 foot trailer with a load. Works great.

Sold trailer. Purchaser happy with upgraded hitch, purchase price reflected upgrade. Pulled 20 ft container office to AZ and dead headed back. 3500 miles no issue.


Completely satisfied and extremely grateful for this item. Very strongly built. We use it on our 3 axle trailer hauling feed for our farm animals.


Held up nicely even with many dry runs on the ball.


Super fast shipping along with great pricing. Hitch showed up just as described and bolted right into place.


I would not buy this again (T4855300). I took it off my trailer. I give etrailer 5 stars.


We like this Coupler, strong and reliab le.


Exactly what I hoped it would be. Old style American excellence. Heavy-duty and holes and bolts were perfect. Fast delivery too. I don't get to praise much of anything these days :)


Great customer service over the phone answering questions and placing order. Quick shipping.


I just installed it. Awesome. Perfect fit and very well built.

Replace a coupler that was held on with 2 bolts after 1 bolt failed. Love the security and strength this one has with 3 bolts. Have had issues with couple not releasing from the ball. Gets stuck in the locked position.
