I have a 93 cherokee that i want to put a lift kit on. I am thinking of 3 inches for now and don't know if going add a leaf is the way to go or new springs packs. My jeep has 270,000kms om it and i think the springs are toast so putting a add a leaf seems pointless to me or is it going to bring the old springs back to life???? I live in lloydminster saskatchewan, where is the best and closest place to get a good kit and what is the best kind out there.
Thanks Dan.I
