I have a stock jeep now. It has 31x10.50x15 tires on it. I'm going to be running 33x12.5x17 tires soon. Do I need a lift kit? I am looking at the quadratec 3" suspension lift with springs and shocks and bump stops. If I need a lift, will this be good enough? I don't do any rock crawling. The most I do off road wise is hunt from it. Thanks in advance.
