Hello, Does anyone happen to know the factory front and rear spring rates for a 1995 Caprice LT1 B4U w/ the FE3 package and tow pack? Spring tag on rears is THH. I have heard that these are the stiffest factory spring put on 94-96 B-Bodies including Impala SS and 9C1's. Is this true? Car does ride like a truck...Which is OK...Has Monroe Severe Service shocks also that I put on...Thank you, Uvaldi..
