I have some used 56" rear springs from a suburban. Can I take 1 or 2 of the leaves out and add them to my front spring pack to get some lift? If so how much lift would I get and how hard would the ride be? Just looking for a cheap way to lift it a couple of inches. A couple of center pins and new u-bolts shouldn't cost me to much. I figure I can put blocks in the rear to match the lift I get in the front.
