Do what YOU want. I personally would not lift it any more than a couple inches. I have had everything from a 1974 Ramcharger with 8in of lift and 40in tyres to a Blazer with a big lift and too much lift does no good off or on road and I have found with everything from mild to somewhat wild off roading a lift does no good either. Unless you want to do it strictly for looks a lift is not needed unless of course you plan to rick crawl a Toyo truck......
