Ok, I'm running a 2.5" block, factory rear springs with a ORD 4" Shackle flip and stock shackles. One of my blocks are broken and I would like to do away with them all together. I can't see spending the money on a set of 2" rear lift springs, when there are other routes that I could go. My question is can I run the ford 57"ers and eliminate the blocks all together? I'm looking to be around the 6-7" lift range. If I run the Ford springs then that will move my axle back correct? I will also have to take the shackle flip off and swap sides also correct? Sorry for all the questions but I don't want to have to change it up for awhile. Thanks.
