The air-max shocks did what I wanted them to. That is the good part of it. The bad part is that one of them leaked. I removed them and found it to be leaking where the air stem attaches to the shock. I cleaned up the leak area and applied J-B weld. So far it is holding air. I also question whether they are Monroe shocks or knockoffs. If it continues to hold air over the long run then it was easier to repair it than send them back.
