Originally dropped spindles & springs. Those springs were too soft.
Kept the spindles & went to a stock spring with a coil cut. Cutting increases the spring rate.
Thinking about pulling those springs & going to a light 3/4 ton spring with about 1.75 coils cut. That's probably too stiff of a ride for most people.

From the info I have found my 1/2 ton ECSB with small block has the same coil springs as are used in the big block trucs, Suburban and 3/4 ton trucks. If this info is correct I already have a 3/4 ton front spring. Belltech also uses the same part # for ECSB, 454 SS, 3/4 ton and Suburban...different part# for RCSB with small block. With that being said, I will just cut my stock coils instead of seeking out a 3/4 ton spring from the bone yard.
