The Beatrush alternator pulley is made out of aluminum and only weighs a mere .17LBS. It retains the original circumference and size and is not a under drive pulley. It is designed with most of the mass concentrated in the center to provide faster rotation yet still retains sufficient material on the outer ring for strength. By reducing the weight of the alternator pulley, the rotating mass is decreased and therefore decreases horsepower and torque loss at the wheels.
