Most gooseneck trailers are designed to be towed on a gooseneck hitch ball located in the bed of the tow vehicle. However, this king pin and pipe assembly is designed for those wanting to tow a gooseneck trailer with a 5th wheel hitch. The 4" O.D. square tube will fit as an inner pipe on most standard gooseneck outer tubes. Always follow manufacturer's torque specs when tightening set screws. This adapter is used to convert the HBQ2516ADJ Bulldog coupler to a king pin fifth wheel adapter.

Customer Satisfied I Have a 36' Float gooseneck trailer that we use for our hay business. We recently decided to change to a small semi and replace our one ton trucks for pulling due to the size of the loads we carry. After a little research we found that we could change our hitch out and pull the trailers that we have instead of replacing them. I priced around on the internet and found etrailer.com was the best price with free shipping! I ordered the hitch online and instantly received an order confirmation followed quickly by the shipped confirmation. I was also quickly informed that the shipping had been sped up and i would receive it even quicker! I was able to follow the progress of the tracking the whole time. I was very satisfied and will return for more trailer parts needs in the future. Sincerely, Clark Fabris Oklahoma Hay Express Inc. 5169
