This adapter is solid steel Kingpin hydrogen welded to a hardened steel 25000# 2 5/16  painted enamel black paint. (Sometimes if the trailers goose neck is offset you may need to block your fifth wheel plate to keep it from tilting. This is an almost impossible item to find, and certainly makes your trucks hitch more useful allowing you to pull goose neck type trailers with a semi-tractor or other truck with a fifth wheel plate. The main post of your goose neck trailer may have to be adjusted to allow the trailer to ride level. You will love this handy adapter. The Kingpin is rated for 80,000# , typical for semi-tractor fifth wheel plates. Load rated for 25000 lbs max. The Seller assumes no liability for the use of this item. This is all  based on USA type fifth wheels. This ad does not include a compensation ring. Measurement B on the drawing is .5" if you cannot adjust for this please see my other ad that does include the .375 compensation ring which will take up most of the slack and still allow room for removal.
Some pick up truck fifth wheels swivel 360 deg and may not be block or lockable and this adapter will not work with these.Some pick up truck fifth wheel heights are too tall by the time the adapter adds 4.5 - 5" to the height and if there isn't enough adjustment on the trailer bolster post will not allow the trailer to ride level which is not recommended. Please take this in consideration before ordering. We do not accept returns.

Due to the inability to get the steel to make our original compensation ring I searched for an alternative and this has worked out fine as a suitable replacement, made from very durable high density polyethylene
