How Does Buyers Products BKPT809B Kingpin Install to Trailer

Published 12/12/2022

Question:

Do you have installation instructions for this kingpin? When I am looking at the holes the counterbores are on the pin side and the surface has a slight taper. It is the same product that is being sold here.

I can see the tag in your picture and can tell that what you have is the Buyers Products King Pin part # 337BKPT809B. This is designed to be bolted to a recessed bolt plate on a trailer and once installed the nuts would be lower than the cut out area for the king pin so that they wouldn't drag. If your trailer does not have the needed plate you'd want to contact a welder in your area as they'd be able to help with that.
