GrimmSpeed Lightweight Crank Pulley Black - Subaru Models (i-`nc. 2002-2014 WRX / 2004+ STI)

Spectral Performance proudly carries a great selection of quality aftermarket performance products brought to you by GrimmSpeed. 

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.

Additionally, these lightweight crank pulleys are available in a variety of anodized finishes to improve the overall engine bay aesthetics.
