04-10 Mazda RX-8 Agency Power Crank Pulley

Quicker throttle response, increased horsepower, and improved drivability are just some of the characteristics the Agency Power under drive pulley kit offers for the Mazda RX-8. The pulley is CNC machined 6061 aluminum and anodized in Blue or Silver. The Agency Power logo is laser engraved for a stylish finish. Each pulley is made to factory specs to give perfect drivability and fitment. This pulley is an under driven pulley- roughly 20% reduced from the factory component. By having a lightweight and under driven pulley, it will offer much needed throttle response and increase of about 9HP. Each pulley includes new hardware for a bolt on installation and brand new belts for a perfect fit on your Mazda RX-8.
