Change Toe or Camber +-1deg on the rear of GM's Theta Platform vehicles with this cam nut. Make the adjustment you need easy by installing this cam nut on the toe link's bolt and then driving the change you need in combination with a cam nut on the camber link. (Note: Most vehicles come with a cam nut on the 'camber link' and a standard, non-offset , nut on the 'toe link.' Changing toe will affect camber and vice versa.) If the camber cam nut is corroded or missing, use this cam in that position too. You may need up to four (4) cam nuts per vehicle. California Residents WARNING
