i did this with a regular set of frnt springs,i used the rear spring pack minus the main spring and the overload. i used 3 springs from the rear spring pack to force my stock front springs into a positive arch. all it cost was the price of the new tiebolt. a 3'' block in the rear leveled it out just perfect. its been a few months shy of 3 yrs. and no trouble as of yet! just make sure to put the leaves inside of the band that keeps the springs all inline, i believe i made awhole new strap or modified the original so it would wrap the thicker spring pack. this truck gets beat on hard, i drive it like a demolition derby car(bouncing off trees and over some very rough terrain,so they have been treated like $hyt) and like i said no trouble thus far and the ride isn't that bad either.
