GrimmSpeed Black Lightweight Crank Pulley Subaru WRX 06-22

Eliminating rotational mass while maintaining a safe presence can increase reliability and bring faster Rev s! For our Lightweight Crank Pulley we pulled out all of the stops. CNC machined from 6061 T6 Aluminum our 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. We designed the pulley with the optimum weight for performance while avoiding misfire CEL s and engine hesitation.

Here at GrimmSpeed innovation is the standard with every product we release and our pulley is no exception. We have designed the only aftermarket pulley installation and removal tool that works with each style of OEM Subaru pulley as well as our aftermarket lightweight pulley. To take it one step further we have also designed the only compatible aftermarket stretch belt installation kit for all 2008+ Subaru Models.

Achieving balance between performance and design while not sacrificing either, it s what you can expect from GrimmSpeed

Notes:

Based on our analysis, the OEM crank pulley does not act as a harmonic damper found on for example traditional V8 engine dampers. The elastomer portion of the pulley helps dampen some noise from the engine accessories (ie. alternator, PS pump, and A/C compressor) but in our experience, the increase in this noise is in-perceivable.
