I'm trying to get about a 1" lift in the front of my blazer. I have an extra set of leafs that i am thinking of sandwitching in the spring pack. currently i have 3 leafs, i'd end up with 4 leafs in front. I know that i would have to change the center pin. I thought about the ORD 1"addaleaf, but if i can get similar results with the extra leaf i'd only have to spend on the center pin and u-bolts. Any draw backs on doing this?? thanks, ARQ.
