how are the SOA setups using waggy, FSJ, or Cherokee rear springs working out? any pics?

I have used both YJ and Wagoneer springs. I am quite pleased with the Wagoneer springs softness and flexability. The only problem I ran into was contact with my 9 inch and the fuel tank and the front main spring peeling away from the pack when the shackle inverts. I will get shackles to resolve that and raise my tank here in a bit. I don't think I will use anything other than a Wagoneer front spring again...mostly due to the fact my rear wheel wells are cut to accomodate the offset pins in the springs and moving of the rear axle rearward.

How many leaf waggy springs did you use?

i use the jc whitney 7leaf hd springs for the rear of a cj on all 4 corners. they are military wrapped on both ends and flex really well. others have had good luck running the same springs also. do a search on them. :D
