Trevor I believe it was pretty obvious to the casual reader that Gary was asking the question in trying to help you. Had he not asked those questions we would not know that what you meant by "Air suspension" was merely OEM air shocks. Not speaking for Gary but I believe, at least for me, that's where the confusion came from. When people speak or "air suspension" they're usually referring to something like Legend Suspension and not the stock OEM air shocks. I hope your frustration is in not getting an immediate answer to your question and not that your fuse is to short to truely understand the line of Gary's questions of you.
Stick around Trevor......you're going to learn more about that new (to you) CVO Ultra Classic than any Harley dealership could ever tell you. And from these owner/riders, for the most part it will be fact and not merely because they're trying to sell you something or simply because they don't know the answer and have to big of an ego to admit it. This place is a wealth of information and you're about to learn that, now that we know what you really meant.
One other thing before I offer my suggestion to your question....your post is now in the correct place and most here know the answer to your question even though they may not ride a CVO Ultra Classic like you and I do.....they make them for all models.

http://www.cvoharley.com/smf/index.php?topic=2539.0My suggestion for your original question.....there are several ways of getting that rear lowered but I believe the most common would be Legend Suspension. It will drop your fender right down on your tire and several of our members have this system. I suggest having somebody install this that's installed on an Ultra Classic before because they'll know to relocate your wiring, etc. up inside your rear fender. You can find them here....
