According to Perrin:

The PERRIN Performance Crank Pulley weighs just 1.2 lbs, which is 4-pounds lighter than the stock 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.
