Or as Dodge calles them "AIR DEFLCETORS" . Ugh. Pretty straightforward once you get the car on stands and take the front wheels off. The only deviation from the instructions I suggest is that you install them about an inch and a half from the bump on the arm and not 3/4 of an inch. If you try to do the 3/4 of an inch route, you will break the "DEFLCETOR" when you tighten it down because the arm curves slightly due to a thickening of the metal in that area.
