^True, I didn't think about that. Just get some stock 1/2 ton keys and a 1" bigger block for the rear, gave my buddy's boss my keys when I put in my level kit and his duramax sits perfectly level and I think he's got some more bolt left too. Another thing that I just thought about too, I'm sure shocks for a 1/2 ton wouldn't be stiff enough for a 3/4 ton so call Bilstein and see what they recommend for your truck. They'll be a little more money, but going the level route is much cheaper than a lift, so you could splurge a little on shocks.
