Suspension Problems

[79TEXASTOY]

I have a 79 Pickup with a Chevy 350 and 700R4 Trans, a Heavy Duty 6 inch lift from Northwest Offroad, es3000 Procomp shocks and the truck is very rough offroad and on concrete. The spring rate is progressive 300-500 lbs per spring. What can or should I do to get a softer ride? :boing

skyjacker springs, coils, or maybe some 1/2 stock 2wd rears that are 63 inches long.

Pro-Comp shocks tend to be stiff too.

he is right 63 inch chevy's ride like a caddy, I haven't setup coils yet but I have heard Aerostar vans work nice.
