If I remember correctly the main 4 inch frame tubes in the standard Kirkham chassis are slightly thicker steel than the original chassis rails, so from that alone, they would be stiffer than originals at a slight penalty in weight. I think a thick fiberglass body such as ERA uses is a little heavier than a Kirkham body also.
