leaf springs on a '04 F-250
I've got a '04 F-250 FX4 6.0L CCSB and it has a leveling kit on it....but the springs look worn out. They don't much of an "arch" anymore. They almost flattened out on the front and I have the F250 rear block w/ no overload springs. I wanted to raise the truck up a little so my 35s will not scrub. Should I do add-a-leafs or replace the whole leaf spring? If replacing, does someone sell a pair w/ the leveling springs already on? I was thinking of putting the F350 block in the rear. Would that mess anything up?
