Typically the max wear on a king pin is .080 of an inch with a minimum diameter of 1.920. DOT says the max wear is .125 of an inch with a minimum diameter of 1.875. When new the king pin will have 2 inches of diameter. See the image I made for you showing the dimensions of a weld on king pin.

Hey David, from previous customers of ours who have the same 2020 Keystone Raptor 424 we have determined that your pin box style is the Lippert 1621 which means for a Gen-Y gooseneck adapter you'd want the #GY58GR that you referenced.
