Grimmspeed Lightweight Crank Pulleys | 2002-2013 Subaru WRX and 2004-2013 Subaru WRX STI (095015) GrimmSpeed

Multiple Subaru Fitments Lightweight Crank Pulleys by Grimmspeed

In our opinion, the OEM Subaru crank pulley has been a cause for concern ever since its original design. It is relatively 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 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 the balance between performance and design while not sacrificing either, it’s what you can expect from GrimmSpeed™.

Features

• Factory Fit for a clean install
• Optimum weight to avoid misfire CELs or hesitation
• Balanced CNC machined 6061 T6 anodized Aluminum
• Includes OEM timing marks for timing verification

Benefits

• Decreases rotational mass more than 3.5lbs over OEM (You will see much faster revs as a result)

Please Note: 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.
