lol, I have an 09 Silverado 2WD that I want to lift as well.. I also love the look! Looks meanI love the look and always wanted to have a lifted truck. And a 2wd is what I got and is all I have to lift.
So, I'm going to try to do it regardless of 2wd or 4wd. I think on street it doesn't really matter anyways since no one is going to know whether it's 2wd or 4wd except for me.
