I Currently have a set of 6" EZ ride springs on the front of my 70 blazer and an add a leaf and blocks in the back. I would like t get rid of the rear blocks but I don't know how to go about it. I hear a lot of guys using both a shackle flip and a new set of springs but why? Why not just get a set of 6" springs instead of a shackle flip and 2" springs. Will the ride quality be that much better or worse? The rear springs seem to cost essentially the same regardless of how much lift they are.
