I had two shims and could engage them without jacking up the rear. However I liked it better towing with all three shims (requires jacking up only the rear to engage). I just leave them engaged during tow season. I actually think my 2011 F250 feels a lot more stable and certainly has less bounce than the stock suspension without the SLs when unloaded.
