Description

Matching our signature Crank Pulley design, the PERRIN Alternator Pulley decreases rotational weight while maintaining good looks. 

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.

Designed to match the PERRIN Crank Pulley, the precision-machined grooves tightly sync with all OEM and aftermarket belts. 

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.
