I was reading and what I came up with is that I can lift my truck four inches without having to worry about boot problems and other problems arising. From the research I've done I've concluded that the bilsteins will lift 2" and act as a .5" spacer so total you get 2.5" of lift is this correct? So if I were to get my two inch spacer and put it on with the bilsteing and put them at middle perch that gives me 4" total of lift and that can be acquired as long as I have after market Ucas?
