I am at 5.5" fine. Some people just over look areas that need to be adressed when lifting. My only problems were death wobble but and adj trac bar up front from an XJ ($50) fixed it for the most part and can drive to school going 50mph while I wait for the rear adj trac bar to arrive.
I just bought 6" springs in the group buy over one JU, but i havent installed them yet. Im going to buy 3" fronts to go in the rears to match the 6". Oh by the way they are made by national spring which i think is skyjacker.
