Decreases Rotational Mass

The PERRIN Performance Crank Pulley weighs just 1.2 lbs., which is 4 lbs. lighter than the OEM crank pulley. This reduction in weight from the crank shaft is equal to removing more than 100 lbs. of vehicle weight! Throttle response, horsepower, and torque are all increased with this easy-to-install part.
