Ok so I'm deff going with the 4"lift, But jeep said there lift would be around $4k before labor!!..Because I heard you gotta have some Computer intalled so that your quadra trac 2 doesn't kick in, so then I started thinking about it do I really even need the Computer intalled??..Why couldn't I just turn off my traction control, doing that would deff turn off my 4X4 wouldn't it?!!..So basically should I just go to tuff country down the street and have them just through a 4"lift on my truck with out the Computer?? ????....Let me know what ya'll think!..
