Anything lower than 6 in the rear and you will have to have some type of frame notch and most likely have to do something with the bed floor to keep the rear end from hammering it.

Up front 4 possibly 5 inches with a static drop using the stock type suspension. The only way I know to get 6/8 without bags would be a 2 inch body drop and a 4/6 static drop. Im not sure what kind of tire clearance issues you might run into if you dropped the front 6 inches.
