You can buy an adjustable height front Bilstein strut to level the truck out if you want to save money. "Bigger" shocks won't provide lift, or proper shock travel. If you want to spend more money, you could go for a coil-over shock in the front (Icon, Fox, Bilstein, Camburg, Total Chaos, etc.) and you can go with a nice set of Bilstein's 5100's or whatever you want in the rear. I'm sure if you do some searching, you'll run accross all kinds of lift options with coil-over or bushing/puck/spacer lifts. Just depends on what you want to do with it, and how much money you're willing to throw at it. Nice thing is that with your truck being 2wd, you can crank it up and not worry about the front CV's.
