i read a thread on pbb about front leafs and rear coils. it started with a guy wanting to put leafs on the front of his tj. it seems that is a very popular setup and i'm thinking about doing it myself. currently i have waggy front and yj rear in spring over config.

another option for front coils may be the ford radius arm/panhard bar setup. i looks pretty simple. you would just need long radius arms for lots of travel. probably not as good as a 4 link but it would be pretty cheap if you used junkyard parts. just an idea. i've never seen it on a jeep and don't know if the stuff would even fit but it's worth the research.
