The OEM Subaru crank pulley has been a cause for concern ever since its original design. It is extremely heavy, susceptible to catastrophic failure, and quite unsightly. Continuing to use this on our cars just wouldn't do. Eliminating rotational mass while maintaining a safe presence can increase reliability and bring faster Rev's!

For this Lightweight Crank Pulley GrimmSpeed pulled out all of the stops. CNC machined from 6061 T6 Aluminum this pulley makes no compromise. It weighs in at 3.5lbs 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. GrimmSpeed designed the pulley with the optimum weight for performance while avoiding misfire CEL's and engine hesitation.
