Trying to find the stock rear leaf spring rate.
It's somewhere in the 120-140 range. My 2001 CC non-RT is 130 pounds per inch, with three 1/4" leafs. You do not count the 1/2" overload spring.
Calculator I used - https://www.suspensionmaxx.com/tech-...ng-calculator/
On mine, I have
2.5" wide x 1 Leaf x 56" long x .25" thick = 19.38 lb/in
2.5" wide x 1 leaf x 45" long x .25" thick = 37.35 lb/in
2.5" wide x 1 leaf x 36" long x .25" thick = 72.96 lb/in
Total = 129.69 lb/in, or basically 130 lb/in

Great info - thank you very much!
