Agency Power has just released their brand new EVO VIII and IX 4G63 Light Weight crank pulley. The pulley is a direct bolt on using the factory belt. The AP pulley weights about 1.1lb compared to the stock pulley weighing in at 4lbs. The weight savings in rotational mass equates to serious performance increases. Don't worry about the stories you have read on crankwalk or unbalancing the motor. The factory harmonic balancer reduces engine noise and vibration in the cabin and deleting this will NOT destroy your motor. The pulley is completely safe as a bolt on giving you between 3-6 horsepower and increased throttle response. Tested and used on many high horsepower EVO 8's and 9's!
