    I've got a set of brand-new, never used Progressive shocks with dual-rate, all black springs. I got this set of bad Progressives with blue lower springs. Does anyone know the difference in spring rate? That is to say, which one would be softer/stiffer?

    Measure the wire size. The thicker, the stiffer.
