When this gasoline version is used, the rpms on the dash are no longer correct. The 2nd, even larger issue, is the belt tensioner falls out of range and the belt is too long causing a squeaky belt and shorter belt life. Changing to this pulley fixes the dash rpms, brings the belt tensioner back to center and provides proper belt tension for maximum life.
This pulley is made of 6061 aluminum anodized for corrosion resistance.
How to tell if you have the wrong pulley on your vehicle? Measure the outside diameter of the pulley flange. You do not need to pull the belt off measuring this way. If your pulley is approximately 2.36" OD, you have the wrong one and need ours.
