For one, try looking for off the shelf reasonably priced shocks that will mount right up and offer compressed and extended measurements that will work for a 2-3" lift without the compressed length being too much that would cause the shock to bottom out. If you compare the numbers, the front shocks bolt right up, are only 1/8" more on compression but are 3 1/8" longer for the lift height and for extra droop on flex. For the rear, the compressed length is 1 5/8" longer on compression than stock shocks, and 3" longer on extension. The extended lengths, although important, aren't as important as the compressed lengths. With 2-3" lift, the compressed length of the rear works out pretty good, and with all suspension modifications, if you bumpstop properly, the extra length in compression shouldn't matter anyways.
