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 Grimmspeeds Lightweight Crank Pulley they pulled out all of the stops. CNC machined from 6061 T6 Aluminum Grimmspeeds 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.
GrimmSpeeds innovation is the standard with every product they release and the pulley is no exception. They have designed the only aftermarket pulley installation and removal tool that works with each style of OEM Subaru pulley as well as their aftermarket lightweight pulley. To take it one step further they 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

I have not done a dyno but 3000-4500 rpms never felt so alive in my Subaru. I researched aftermarket pulley systems for months before purchasing the GS pulley from horsepower freaks, the actual product weight is perfectly balanced say compared to Perrin and Cobb which do weigh less, but have cel problems because of the lack of enough weight. I would say I feel my car is faster through the power band, idles smoother and revs a heck of alot quicker, all from a little pulley. I recommend this product and purchasing from HPF to anyone
