1969 American/Jav/AMX Spring rates

[farna@xxxxxxx]

I included Javelin and AMX rates just in case you want to mix and match springs. As far as I know the SC/Rambler used the optional heavy spring rates, which were the same for the AMX. Javelin V-8 heavy springs were a bit stiffer. Since the 4.0L is a little lighter than an old 232, at least 40 pouinds lighter, I'd try the light (standard) V-8 wagon springs, or V-8 wagon W/AC at the most. I think over 100#/inch would be a bit on the stiff side, and it may sit a little higher since you should have no more than 800# on each spring. Shorten to about 9.75" to retain stock height, or maybe 9.50" (assuming all other stock specs, like loaded hgt. weight).
