A buddy of mine who works in a truck shop (lifts, suspension, all that good stuff) told me something about being able to level my truck without anything but a turn of a wrench. I'm just wondering if anyone knows anything about this. He said I should jack the front end up and there will be a certain screw on either side that if I tighten I should be able to get about 2 inches higher just by that turn of the wrench. I'm new to the whole suspension ordeal and am a little confused. I can get more info on this but has anybody heard of this or does anybody know what screw he's talking about?
