I noticed a little green tag on my TC rear springs and I was wondering if anyone could tell me what it means.

HRE
E7SC <- reguesstimate
35.0/4086
5560-KA

Thanks a bunch.

Antonio.

The 35.0 is the initial spring rate in N/mm. That converts to 200lb/in. That's a pretty standard spring rate for the Foxes. Since all but a rare few have linear rear springs, that is the initial spring rate. Usually they are 200-300# progressive.

The 4086 is the load rating in N. That converts to 918 lbf. (Pounds force). That's lighter than the original rear springs in my 84 XR-7 (944 lbf), but still much higher than most Fox Mustang rears, and even the SN-95's aren't that high, but they get closer.
