My guess, looking at the angle of the lower control arms, your springs are either lowering ones (doubtful) or are sagging a lot. IIRC, the lower arms would be level or slightly down angle.
Also, keep in mind that 1" of travel at the bump stop is close to 2" of travel at the wheel. If you want more travel, you can remove the factory bump stop and add a short bump stop like I have. Works great.
