Hey guys, I have an '05 7lug 4x4 with an AS 2.5. I still have about 1/2-1" rake in the back and I want it completely leveled if not a tad nose-high. Options would be to run a lowering shackle that is adjustable to either 1" or 2" and the other option is to swap out the blocks for a shorter one (maybe off a 2wd). I know some years had more rake stock than others. How big exactly are the 4x4 blocks vs the 2x4 blocks? Can I just buy a set of 1" universal blocks and swap em out? Or even go to a full 3" spacer up front?
