Perrin 93-11 Subaru Impreza / 04-21 STI / 02-14 WRX EJ Engines (w/o AC ONLY) Crank Pulley - Blue - PSP-ENG-102BL

The PERRIN Lightweight Crank Pulley lightens up your rotating engine parts to free up power. True weight savings can be felt with every blip of the gas pedal.

This crank pulley has been designed to reduce the rotational mass of your engine to promote faster revs, and better response, with increased performance. Additionally, this crank pulley version has been designed for those who have removed the AC belt drive to allow for those building engines to make the highest levels of horsepower and torque. 

DETAILS:

• Anodized blue finish with white PERRIN logo
• Weighs just 1.0 lbs which is 4 lbs lighter than the stock OEM crank pulley
• The reduction in weight from the crankshaft is equal to removing more than 100lbs of vehicle weight
• Machined from 6061 T6 billet aluminum materials
• Precision machined grooves that tightly sync with all OEM and aftermarket belts

NOTE:

• For models WITHOUT AC
