King pin coupler allows you to pull your gooseneck trailer with a fifth-wheel hitch. The height easily adjusts to fit your application. Square inner tube is included.The king pin adapter works great and I won't have to switch back-and-forth between gooseneck ball and fifth wheel hitch anymore. I found the best price at the etrailer.com .
My pickup engine went down being unable to pull a my gooseneck with a ball application I ordered your 4 in kinpin adapter for a gooseneck trailer as you can see in the pictures it pinned in perfectly with no trouble at all with your adapter im able to get my trailers moves while repairs are made and with it i'll just have to use the fifth wheel hitch for the pickup witch is much more easy to use than a goose ball
Has held up well to the wear and tear of my overloaded trailer. Very good quality item and well built.
It was just a little bit heavier than I expected which really means that's great thank you
Item was as advertised. and came to me undamaged and timely
Well built product. Only problem is the holes were too small for my locking pin. Just used a die grinder to open them up a little and fit great. I did paint it also, came bare.
Quality manufacturing. I have a 1989 gooseneck car hauler with a 4 1/2 inch OD square tube and I'm changing it over to a king pin. This is a 4 inch OD and it fits perfectly inside my existing tubing. The holes aren't the same size as my original 4 1/2 inch but that's an easy fix. I can't wait to be able to tow my 5th wheel and my car hauler without having to switch from king pin to gooseneck ??????
Super fast shipping, it was exactly what I imagined it being when I ordered it.
This thing works. No hassles with hitching and I don't have to swap out my fifth wheel from the truck (which pulls the camper too) to use the equipment trailer.
The fifth wheel is easier to hitch and disconnect than the ball hitch that it replaced.
I see no disadvantages, except that my neighbors can't just borrow my trailer.
This gooseneck to 5th wheel adapter was an excellent decision, hooking up my equipment trailer is now as piece of cake.
