The OEM Subaru crank pulley has been a cause for concern ever since its original design. It's relatively heavy, susceptible to catastrophic failure, and quite unsightly.

Eliminating rotational mass while maintaining a safe presence can increase reliability and bring faster Rev's!

CNC machined from 6061 T6 Aluminum our pulley makes no compromise. It weighs in at 3.5 pounds lighter than OEM while at the same time increasing its durability. Marked with a timing mark and perfect cut keyway makes this install a breeze.

  • Balanced CNC machined 6061 T6 anodized Aluminum 
  • Includes OEM timing marks for timing verification
