i'm thinking about doing this now. my front end is sagging quite a bit now. I like shannon's method but that is for the F350. Stock isn't the 350 taller than the F250? Maybe there the same height and mine is just sagging alot. It says that it lowered the 350 about an inch, would it lower my 250 an inch too?

In stock trim the F350 sits taller than the F250.

It would probely lower it the same but its no big deal just use W or X code springs and get it back up.

Wait a second, are you talking about doing the SD springs and mounts with the TTB axle?

If so, there is a problem-the spring rate will be way too soft with the SD springs even the x codes I bet. You can do an RSK with the TTB if you use the stock springs and some center pivot brackets but I don't think you will want to do SD springs with the TTB still being in 2 pieces.

I did both, first the RSK with the TTB and built the right length center pivot brackets but used the stock springs gained 4.5" lift.
Now have the SD springs same lift but the TTB is one piece so the leverage is much less and spring rate is perfect.
