Mine had the heavy duty 11 leaf front, 10 leaf rear spring package from the Factory (maybe that is why the plow didn't kill it!). That is what I put back in it. It rides ok, but still not great. I agree, there should be more leafs in the front than the rear simply because of the engine weight. I would get the same that was in it.
Oh, and one thing I noticed too with the springs I used, I don't get that jeep lean. �;)
