I think all Expo leafs will gain you 2" of lift. Take out your block, you gonna be a -.5" lift. Add shackle, you going to be at 1" of lift.
Using an AAL and a shackle, you'll gain approx 3" of lift. Take out your block, and you'll be at 1/2" of lift. AAL, shackle, and stock block is my rear set up to match my 4" superlift.
