I believe that you are right. I need to put a slightly longer shock on the truck. I hear a clicking noise regularly now when I change direction or turn. One short click and then nothing more. I have a feeling it is coming from my maxed out rear shock since it began after I lifted the vehicle. Any thoughts on all that?You sure about that? Adding a spacer above or below the spring will cause the piston inside the shock to move proportionally. Making it's neutral postion closer to either the top or bottom of the shock housing. If your shocks can't account for that offset you'll still max it out.
