I put the 6" Zone lift on 2 years ago and love it. I have 2007.5 4 door long box - 20" rims and 35" tires. You still need to trim the front bumper and fenders a bit. I did because I live in Montana and use my truck for towing and hunting which requires chains on the truck. Great kit and went together really easy! The only thing I would recommend is getting the Idler/Pitman arm brackets and putting them on when you do the kit. You already have everything torn down and I wish I would have done it then.
