About an inch and a half. I'm sure my shocks are junk too. I have some brand new F350 shocks that are taller, but that'd screw up my alignment and wear the outsides of the tires.... not to mention they would bottom out.

What makes the 2wd 250s, 350s, and 4x4 150s taller any way? I know the 250 ups have leafs and are way different.
