I just got my 94 explorer up and running from doing a SOA and James duff parts in the front. You will get 5-6" just doing the soa, no need for blocks.
I would stay away from that super lift kit. I looked into it and alot of people have had it pulled it off due to to much noise from it moving around while driving. Also not worth the money. I bought a set of balistic fab leaf spring perches and shock mount conversion brackets and have about 100 into parts including new shackels. And couldn't be happier with the ride even with a set off bad rear shocks.
