Alright, I am new to the whole, Grand Cherokee thing, I have owned a T.J.,X.J.,C.J., and now my Z.J., my question is...I installed the bb from daystar, and my brother rececently gave me his used discos from his T.J. I installed them, and everything seems to fit...does anyone see a problem with running these? They are tera units I believe for 0-2 inchs of lift.
