Have a ZJ I am planing on putting a 4 inch lift on this fall. My question is I see a lift kit that come with everything (shacks, springs, control arms) do I need anything else like drop my rear end. Someone told me anything bigger then 4 inches I'd need to drop my pumpkin down to reach.

Or could someone give me a list of what I'd need to lift it 4 inchs?..

One of the lift kits I'm looking at is ( rusty's offroad 3" basic kit ) with maybe adding 1" spacers...
