what the ground clearence under the frame rail by the toe board?
are you touching the inner top of the fender right now? if so the the super slammer will work for you
I should be at the same height as Ross at ride height and dropped 2 inches when I let the air out of the bags. I'm resting on the inner fender currently and I will be moving that up 3-4 inches and I'm running a 2" drop spindle as well.
