2" Body lift from AC was OK, but I did add an additional bolt to the bottom Radiator support bracket. It seemed way to flimsy with the supplied hardware. I've done two with several guys helping. The first was about 9hrs and the second around 6hrs, so the more you know the better you'll be. Also note if you have the tow hitch you'll have to notch the rear bumper after you re-drill the holes to bring it up with the body. Flimsy metal so it was not a problem!

All in all, if you plan on running larger tires you'll get the room to stuff them after the BL. If you're staying stock size then it would only be helping your approach/departure angles.
