You can crank on the shackle bolts to remove some of the slack. Just be careful not to strip the bolts.

My other thought is you might want to remove those steprails before you drive them into your rear tire or rockerpanels.

Oh, and you can order Bilstein shocks from SLR, extended specifically for the shackle distance.
