More drop is no problem. The shock in the photo Measures - now get this - 22.5" open, and 12.25" closed. Now, not too many of us have use for 10+" of travel, but the longer shock has a larger resivour. To go lower, we just use a shorter shock. The shock shown will still have a 1/2" of stroke left when the axle hits the frame. For trucks with shorter springs and C notches, we use a shock that measures 9" closed, and 16" open. This still has 7" of travel.
