This is the GrimmSpeed Lightweight Crankshaft Pulley. This pulley has been designed to be a lightweight direct replacement of the OEM crank pulley to decrease the overall rotational mass. This is ideal for factory 4-cylinder boxer engine designs that have a shorter crankshaft length, and it will increase the engine revs while improving the engine response. Additionally, these lightweight crank pulleys are available in a variety of anodized finishes to improve the overall engine bay aesthetics.
