Suspension Upgrade

[Sno-Mow]

Ok, I had a 06 F350 with 2 Ton front coils installed plus rear airbag...It was totaled.

I bought a 03 F250 and because I plow snow and the plow was set up for the old truck (push bar was welded) I need the truck to be 4 inches higher.

I was thinking about buying used F350 springs (code x) for the front and springs for the rear (code B) plus blocks and add-a-leaf kit to acheive the total height and capacity I had in the old truck.

Any reason this wouldn't work? I figure seeing as I have the cab off right now to do the heads now would be a perfect time to get the suspension done.

PS...I hung a 975# plow on the old one with NO sag, and need the same.
