I'm a little nieve when it comes to this topic so please forgive in advance. I have a 04 Z71 that I want to put 285/70/18 or close to this size set of wheels on. I know I will have to put some sort of leveling kit or lift on the truck but I don't want anything to aggressive. With that being said the guy at the store said the only lift size for the 04 would be 6inches. I feel this is way to big for me and I also got the feeling from reading some of these threads that there are smaller lifts / leveling kits out there...Any info would be appreciated.
