Add some pep to your 1.6L E-tec II motor with an AveoForum aluminum performance underdrive crankshaft pulley! This lightweight pulley weighs in at only 1.2 lbs! That is 78% less than the stock steel pulley. This 4.2 pound weight reduction allows your engine to be more responsive and send more power to the wheels. In addition to the weight reduction, it is also undersized 15%. Undersizing the pulley makes the accessories spin a little slower which frees up power to send to the wheel. Installation is easy and only takes around 30 minutes!
