Perrin [02-26 WRX, 04-21 STI] Crank Pulley

The PERRIN Lightweight Crank Pulley lightens up your rotating engine parts to free up power - a true weight savings that can be felt with every blip of the gas pedal. Machined from 6061-T6 billet aluminum and hard anodized, it is significantly lighter than the stock pulley for improved throttle response, horsepower and torque. Precision-machined grooves sync tightly with all OEM and aftermarket belts. Select your specific part number and color above - fitment varies by part number.
