King pin coupler allows you to pull your gooseneck trailer with a fifth-wheel hitch. The height easily adjusts to fit your application. Round inner tube is included.I have 3 of them. They are a good product and they are built very well. I recommend them to anyone who wants to convert to a 5th wheel! etrailer is a Great Company to deal with! Take Care!’
Amazing build and great design. This think is thick!
Very excited to see how much better the 34 foot cargo trailer will be with this conversion.
Great product. Allowed me to use a friends gooseneck trailer with my fifth wheel hitch and haul 4 tons of wood pellets! Very easy to put on and take off.
Works as it should, Fits perfectly, Changes to gooseneck in minutes for different vehicle
Great products great prices always on time or early! Product is Exactly as stated in the ad!
I ordered this item and within 2 days it had arrived. Installing it didn’t take over 10 minutes! I use my truck to work during the week and pull my 5th wheel on the weekend! Only thing I’d recommend purchasing is a lube plate to put on the hitch, that way you don’t have to deal with a greasy mess! I’d recommend this hitch to anyone!
Prompt delivery. Have not towed with the adapter yet, but product appears to be very heavy duty with thick walled pipe and very sturdy welds. I am anxious to test it.
This product allows me to use a fifth wheel hitch to haul my 34' camper trailer and quickly convert to haul my 35' gooseneck trailer with my tractor and implements.
My adapter arrived on time with no issues. Adapter has been installed.
Your delivery service is terrible I have purched a few items from you and I have not had one delivered to my house, always neighbors, or not delivered at all. Maybe you should consider a new service.
Nice heavy duty goose neck 5th wheel adapter fit good .
Allowed me to take on other hAuling jobs
Wow I was blown away by your product and received it 2 days earlier a plus not to mention the thickness of this adapter this adapter was build like a tank no paint but for me that’s a plus I can paint it to color match my trailer win win for me and talk about the welds wow that’s an awesome weld job ...I’ll buy your products again hands down I loved it ...way more than expected and for the value you just can’t beat it..quality ..and made in the USA ..need I say more ..
Looks and fits good
Well built for the price. Had to get one to take my class A cdl test, but now I can haul my 40' gooseneck trailer with any truck.
The holes that were drilled in the shaft of the part was not lined up straight they where diagonal and made the plate not useable
I ordered a 30k gooseneck to kingpin conversion for a 40 foot heavy hay trailer. I received my order early. Upon inspection, I was pleased with the construction and then mounted it. it attaches to my single axle road tractor easily. it also provides better stability than the other options available. I am a first time customer and will likely be a repeat customer.
I was told about your website by an RV dealer, I was looking for a goose neck to fifth wheel adapter for a horse trailer I had just purchased. I found what I was looking for at etrailer and ordered it, it was delivered in a couple days and the piece looked great and worked wonderful I was very impressed with the short turnaround time and would highly recommend your business
thanks, we have been using this 5th wheel adapter on a daily bases. It has stabilized the trailer 100%. Very Satisfied with it. Thanks
The web site is organized and easy to order from. The customer service are knowledgeable to answere questions and assist you to finalize your orders.
Makes switch from gooseneck ball hitch trailers to the fifth wheel very easy and only moments to do. Transporting for a living every advantage time wise is a plus.
Hitch sits to high at it's lowest setting both 5th wheel and Adapter set as low as possible .holes in Adapter not drilled in line with plate sits cockeyed on Trailer. Painted yellow for safety.
It lets me use the trailer behind a semi; the load is less stress on the semi that on the 1.5 ton flatbed trucks.
Works great for adapting the goose neck trailer into being able to be used with the 5th wheel plate in the truck
