I know the standard has the 0~57 rating, but I suspect that's to allow for the decreased weight on the same springs used by the heavier models.
Still, this is about an '86 so the 28~57 is the recommended number. I'd think, after all these years, those numbers might increase to take up some of the sag.
Why ain't we ridin'?
