First to start off with you can find them and you have to call but the 2011 will fit and second you will not be able to get 2" of lift on your truck. The Outdoorsman model already has a small level lift on it from the factory. If in fact you do put a leveling kit on it you will only get about .3 inch of lift. I think your best bet for more lift is a 1.25 body lift or go with a 4" suspension lift. Don't really know of any more or different options for you. I hope this helps you out and that i may have steered you in the right direction.
The dealer installed a Rancho Quicklift on mine. http://www.gorancho.com/downloads.php I really like it. The ride quality is just as good if not better than the original and they have nine adjustment levels. I've heard that the puck lift takes away some of the ride quality, but don't know for sure. Everything else is stock. Let me know if you would like some pics and I'll post them.
