FYI. The F350 DRW come with the same blocks as the F250. Atleast mine and the others I have seen do. I had to buy the F350 SRW blocks to raise mine up to match my icon 2.5 lift.
And to the OP you should have a 2 in block between your axle housing and rear spring if its a 4wd. If its a 2wd Im not sure. sorry
