I want to do the f350 blocks in the rear to reaise it up ~2".But what can i do about the front springs to make it level with my rear?? The front sags pretty bad.Its a regular cab 4x4 auto diesel.
Thanks-I only saw reverse shackle kits for the f350 why is that?

 

You should be able to use the reverse shackle kits on either the 250 or 350. They are pretty much identical trucks minus the GVWR and the badges on the side. If you're springs are sagging that bad, you might want to try an add-a-leaf system to raise it up a bit.

That isn't quite true. The F250 has the independent front suspension; the F350 has the straight axle. The shackle reversal kit is designed for the F350's, but nobody makes a kit for the F250. The cheapest way to lift the front is to add-a-leaf. That'll give you 1-1.5". Air bags can be added to the front, and though they'll raise the front 2-3", they make the ride absolutely brutal in the process. I'm not sure how much lift you want to put on, but the add-a-leaf is fairly inexpensive.
