A method of making a galvanized upper coupler assembly for use in a trailer and the corresponding upper coupler assembly apparatus is disclosed. The method comprises the steps of providing a frame, covering at least one area of the frame with a mask, galvanizing the portions of the frame that are not covered, removing the mask, providing a kingpin, and attaching the kingpin to the frame. After attachment of the kingpin to the frame, the combined assembly can be coated with a rust resistant coating. if desired, a cover plate can be attached to the frame, over the kingpin.
