07-13 Chevrolet Silverado/Sierra (All Cabs) 0" to -4" Front / 5"/6" Rear Drop w/ Street Performance Shocks
You really don't need a notch til 7+ inches of drop. This kit also comes with camber bushings to prevent tires from wearing.

I do not recommend air shocks on any fullsize truck. I would go with Street Performance shocks by Belltech and if needed a helper bag system by Airlift.
