Looking for some knowledge folks. My 3/4 ton 1966 gmc pick up is getting front end rebuilt. I called eaton springs and was told the stock spring is thier ML 2022 spring which is rated for about 1018 lbs spring rate. Now when compared to the same year chevy c20 version that spring is considered heavy duty for a chevy c20. Same year in c20 the standard spring is listed as ML1766 which is listed at around 722lbs spring rate, this spring is standard for both c10 and c20.

So question, is does anyone have any knowledge of GMC using heavier duty springs as standard springs? I'm debating going with the c20 version of standard to get a more plush ride, since the standard in GMC is heavy duty version according to Eaton springs. Hopefully someone knows about this or have ran across this at some point. Thanks in advance.
