Replacing the leaf springs is a pretty simple task, as long as the shackles are not rusted shut. Even then some penetrating oil a few hours before working and you should be ok.
I went with an add-a-leaf kit instead of new springs. I ordered a long secondary leaf from Hawk Suzuki so it wouldn't affect my ride to much but would still stop the leaves from going into a negative arch, which is rather common with a SPOA lift. How far backwards are the springs?
