An F350 with a 2.5" leveling kit will put you even with the rear. I have also noticed that since the F350 sits higher from the factory, Adding a 2.5" leveling kit puts you right around the same height as a F250 with a 4" lift.
Not completely true. The F350 is 1" taller in the rear do to a 1" taller block. When you lift a F250 2.5" you need to change the rear blocks to 4" - 5". Where with the F350 most will leave the stock 3.5" rear blocks on. This give the F250 .5" to 1.5" over the F350. If you change the rear blocks on a F350 they would be the same. If your were to put a 4" lift on a F250 or F350 they would be the same.
To the OP: Go with 1" or 2.5" with 4" rear blocks. 2.5" would be the best. That said don't forget the track bar. If you lift your truck your wheels will shift to the left .5" for each 1" of lift. To get your wheels back in track an adjustable track bar is needed.
