52" vs 63" spring rate

[spoolnaround]

Ok after searching for an hour I havent answered my questions.
1. What is the spring rate of a stock 52" Blazer rear spring?
2. What late model Chev has the closest spring rate in a 63" or 64" spring?
3. What is the stock spring rate for the front springs?

I ordered some 57" custom springs from a well known spring co and they made them 56". Well if I am going to move my hanger again I want to go longer not shorter. I figure I will just put the springs I have in front and get new ones (longer) for the rear.

Those of you with the 52's in front, are they too soft? Perfect? Too stiff?
I had these springs made somewhere in the middle of the Ferd 57's and the stock 52's.

I want to say the stock 52 is like 22-2300#'s and the 57" Ferds are 1600#s

Or better yet, I looked but couldnt figure out which company it was that listed all the spring rates for each truck, if you know what it is shoot it!

my guess for closest spring rate for 63's would be an IFS blazer or tahoe.

found out early model. I will keep looking.
looks like my rears will work great for the fronts.

from what ive seen as well as read...only the pickups have the 63's. even into the late 90's the yukons and whatnot had 56's out back.
