Perrin Performance Alternator Pulley for 02-05 WRX and 04-06 STI Blue
Matching our signature Crank Pulley design, the PERRIN Alternator Pulley decreases rotational weight while maintaining good looks.
Decrease Rotational Mass
PERRIN Alternator Pulleys weigh just 0.116 lbs., which is lighter than the OEM alternator pulley. Throttle response, horsepower, and torque are all increased with this easy-to-install part.
Design
Designed to match the PERRIN Crank Pulley, the precision-machined grooves tightly sync with all OEM and aftermarket belts.
Construction
The PERRIN Alternator Pulley is machined from 6061T6 billet aluminum, anodized black, blue, or red, and laser etched for increased belt life and a precision fit.
