So I'd like to bag my 07 Silverado in the next year or so, but wasn't sure what to get. I'm thinking about a 4/6 drop from DJM which includes flip kit, upper and lower arms, shackles and hangars. So is there anything I won't need if Im going to bag it? I don't want to buy the shackles and hangars if they're not going to be used when I bag it.
