I am running 63" chevys in the rear with no blocks, marlin 4" lift springs with the bottom 2 leaves removed and sitting with 37's. It sits nice is very drivable. Should be about 2.5-3" lift by my calculation. With the aftermarket springs up front I did move the front spring hanger forward and have so far only hammered the pinch weld in. The springs settle a bit once you hit a few trails. Oh, I also have an 8274 up front, duals, hardtop in the winter, 6 pt cage and full compliment of tools.

hope that helps!
