Oki the SkyJacker 8" lift kit for our trucks are really cheap. $425. How can someone resist? Now if I was to go from a 4" all the way up to a 8" the same modifications would have to be done correct? I just wanna make sure im not missing anything. Lower Transfer case (how much lower?), Longer drive shafts estimate (how much length and $ ?) longer brake lines front $70, pitman arm $80 along with a Drag link $120, and what would i be missing? Then while i was looking at lifts between kits and systems, how do the 8" kits get that much lift in the rear without a fully new leaf pack? Im asking because they give you the option of blocks in the rear or leafs.
