Here is my view on this topic:
I have 4" ProComp's on my '86 CJ7.
It is on the stiff side, but i'm using the supplied shocks (es3000 ??).
I'm going to change these for a set of Rancho adjustable..
I have loosened the spring clamps and the shackle / frame spring eye bolts.
On the side, they have not sagged at all...
I'm thinking about removing one of the leafs in each spring...
To clear 33", here is what i think is a "killer" setup:
-OME 2.5" rear YJ springs, used front and rear (will need some mods on the front, becuase they are 2.5" wide, stock CJ is 2")
-1" body lift
-3/8" shackle lifts.
This should give you enough clearance, to run 33".
I have driven an YJ with the OME springs, and that was the best leaf sprung Jeep i have ever driven ....
A friend of mine is installing this very setup, it should be finished in a couple of weeks...
Ok, i admit that this setup isn't exactly cheap, but the handling is very, very good....
