Decreasing the overall rotational mass while maintaining a safe presence can increase reliability and engine revs! The GrimmSpeed Lightweight Crank Pulley features a lightweight and durable design for improved performance and engine response. This means no misfire or engine hesitation. This pulley is CNC machined from 6061 T6 Aluminum and is 3.5lbs lighter than the OEM crank pulley. This pulley is further designed with a timing mark and a perfect cut keyway to make the installation a breeze.

I noticed a difference immediately in the driveline! Much easier to rev and much more responsive I am very pleased with this product! Does look very nice under the hood and matches the Grimm speed air oil separator perfectly
Fit on perfect and is way lighter than the factory pully, Also the color is very shiny
Had to change my timing belt and this was a no brainer. Grimmspeed has the best reviews for a reason! Quality finish, fitment, and does what it advertises. Noticeably lightens the drive line and revs come easier.
This is the pulley to buy, people!
Quality part shave some weight and adds a nice splash of color under the hood.
