leveling kit

2.5 should be fine, thats what I had on mine. But I did not like it at all!!! It brought the front wheels closer together. Made the truck look like it needed wide rims really bad!!! I had just purchased new tires & did not want rims. I ended up lowering the rear 2" with shackles and lifting the front about 3/4" to level the truck. Looks like thats the way it should have been from the factory, not extreme at all. Plus I would always get flashed when I was running my fog lights, not anymore.
