his sig does state that he has X springs which I would think lifted his Ex 2.75" seeing that they lift a F250 or 350 1.75"s over stock front springs and he also states rear F350 blocks. I'd start with tires balancing and then go to the driveline shop if that didn't do it. I'm assuming you didn't have this with your old tires? Unless you changed the suspension and tires together w/o driving it with your old tires and new suspension change.

didn't catch that but I still don't think its the shaft. 2" of likt should't be a problem. I ended up getting a Hi Angle CV rear shft and it needed to be reballenced! But my problem ended up being 2 out of round tires. These trucks seem very sensitive, depending on the road it stills vibrates like its the tires, rims or ds.
