This comprehensive kit allows the user to replace the heavy factory crankshaft pulley and cage assembly with a lightweight, precision-machined aluminum hub and interchangeable outer ring.

The kit includes all of the necessary hardware, including a billet bracket to cleanly relocate the factory crank idler pulley.

Once this kit is installed, the user can adjust the vehicle's boost level by simply changing the outer pulley ring to any of the available Metco pulley rings, a process that takes just minutes. This kit is custom-engineered to be a complete bolt-on, with no cutting, drilling, or irreversible changes required.

A special tool is included to assist the installer with removal of the factory pulley retaining bolt.

In most cases, total time required for installation is about two hours.
