I have 4" lift front springs and 4" blocks and aal in the rear. i want the truck to be higher and articulate better in the rear. i am decided on doing the rear home made shackle flip, but i dont know how to make the front equal to the rear after the flip. i figured 4-5" of lift from the flip? I can use 2" lift shackles for the front but what can i do for 3" for lift for the front. add more leafs? any ideas?
