Can you take a pic of your front setup? Also.. if you try to make a shackle lift or spacer lift.. keep in mind it needs to be of HEAVY steel.. and i would not go more than 2 or maybe 3 inches. Shackle lifts have been done for years on jeeps.. but the biggest one you can find are 2 or 3 inches. Probably for a reason.
also keep in mind that if u extend the shackles 3 inches, it will only give u a 1.5 inch lift.....it only moves one end of the leaf spring, so the middle moves half as far as the end....
