i guess i probly dont do enough hard core wheelin to do the sas. if i was to go with an IFS lift it would probly be superlift. probly go with replacement rear springs. although i heard the have a tendancy to sag. although my buddy might sell me his trailmast IFS front kit. hes gonna do a sas and i would give him about $400 for the front. barely ever wheeled with it. cost wise it might be the way to go for now and see how i like the ifs lift. plus with the traveling im gonna do with it seems like the way to go for now.
