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 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™
GrimmSpeed was founded in 2006 to provide customers with innovative and highly engineered products.
The company's founder, Justin Grimm, has always had a passion for Subarus. Just like most enthusiasts, he was satisfied with his vehicle's performance stock, but could not resist the urge to see just how much more potential was left untapped. After a few years of perfecting his ideas and techniques on his own personal Subaru, Justin decided to turn his passion into a career. He immediately realized the niche market for Subaru aftermarket performance and founded GrimmSpeed, initially performing all of the work out of his own garage. As the demand for his own high quality products grew, he opened a new shop in St. Paul, MN. Enthusiasts quickly took to GrimmSpeed, and it became necessary to expand even further to a larger location. In January 2010 GrimmSpeed moved into a 6500 SQ FT shop in Minneapolis, MN. This move has given GrimmSpeed the opportunity to expand for years to come.
Due to the extreme weather conditions of Minnesota, GrimmSpeed has unique opportunities to test their products to ensure quality performance. This allows the engineers to take advantage of a very wide range of conditions for product testing. This enables GrimmSpeed to continuously perform research and development on all products and make revisions accordingly.
