The Grimmspeed Lightweight crank pulley has been designed to improve the performance of your vehicle. This particular crank pulley has a 75% reduction in rotating mass when compared to the factory crank pulley, and has been fabricated from 6061 T6 aluminum. This is a direct replacement of the factory crank pulley, and once installed you will get a little improvement in performance, especially since the factory pulley has a mass of 4.90LBS, where the Grimmspeed unit has a mass of 1.15LBS. 

This particular crank pulley will come in the anodized finish to add a cleaner look to your engine bay.
