Agency Power has designed a Mitsubishi Evo X crank pulley for the 4B11 engine. This new pulley is fully CNC machined 6061 aluminum and is available in a Black or Satin silver finish with the Laser engraved Agency Power logo. The lightweight crank pulley fits all 08-09 EVO X models.
The pulley is a direct bolt on using the factory belt. Using the same diameter as stock, the AP pulley weights about 1.0lbs compared to the stock pulley weighing in at 4lbs. The weight savings in rotational mass equates to serious performance increases. Quicker throttle response, improved rev matching, and more for the serious performance driver.
