I may have missed it but did you check out OME springs? They raised my truck in the back about 3" as it had sagged so bad. They come in medium and hard spring rates. I picked the Mediums as I don't tow and noticed huge improvements in ride quality, steering predictability, and traction. Of course new springs in general will do that over old crusty ones but the point being, my ride is good and not harsh in any way. It will probably be at least tolerable in a shorty.
