The truck sets level, I replaced the Fabtech 1.5" Block with a 2.5" Block to make it level, I was going to go with a 3" block but the U-bolts from Fabtech were only long enough to go to the 2.5" block for now . I'm going to have the rear leafs re-arched or add-a-leaf. If I add-a-leaf I'll go back the the 1.5" block and gain it that way, just another $300 to $400 I don't want to spend yet.
