I have a 2015 jeep wrangler unlimited sport and am wanting to get a 2.5 inch lift, mainly for looks. As well as bigger tires. So my questions are what size tires could I get? Recommendations on lift kits, as well as what all does someone need for a lift? I heard of programmers, axel gears, etc. Is this all needed and how much does this all cost for a decent setup?
