Background: 82 frame with D60 front 8" superlift springs. 14ff with DIy4x rear shackle flip. Brackets mounted backwards (opposite sides from stock) with 6" shackles for better angle. I need to know what lifted 56's will match the 8" front lift 2.5" w/ or w/o zero rate, 4". I expect the front to drop due to the weight of the diesel but do not know how much. Prefer it level, but whatever works. Thanks in advance. justiz00 I have searched and spend days (cumulative) reading old post if I think they may help me. I have seen no info saying swapping a stock 56" in place of a stock 52" yields me X" of lift (if any).
