Agency Power Under driven Crank Pulley Mazda RX-8 03-11

Quicker throttle response, increased horsepower, and improved drivability are just some of the characteristics the all new Agency Power under drive pulley kit offers for the Mazda RX8. Our lightweight and under driven pulley is CNC machined 6061 aluminum. The pulley is anodized in Brilliant Blue or Silver Bright Dip. The Agency Power logo is laser engraved for a stylish finish. Each pulley is made to factory specs to give perfect drivability and fitment.

The pulley is 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 (See Dyno Sheet). Each pulley includes new hardware for a bolt on installation and brand new belts for a perfect fit.
