What is the max amount of lift available from the stock rear springs? I read that you can cut down the springs from the same pack 2.5" and then add them to the existig pack for about 3" of lift (keeping the overload) Would adding an AL to this be able to yield 5" lift? IO am asking because i have the 6" fabtech on my truck and the rear is sitting low. I have 1.5" lift shackles to install which would level it out, but I want to ditch the block. I also have another fabtech AAL I could cut down, but running two AALs even of different lengths may make the ride to harsh. Right now I do not have the cash for new rear springs as I am saving to have my gears done. If it cant work, I will just add the shackle and keep the blocks for now. What do you all think?
