The PERRIN Performance Crank Pulley is up to 3.7 lbs lighter than the stock OEM crank pulley. This decreases the crank shaft weight by the equivalent of over 100 lbs, improving throttle response, horsepower, and torque. Its 6061T6 billet aluminum construction, anodizing, and laser etching guarantee precise fit and superior belt life. The pulley also boasts machined grooves for a perfect synchronization with all OEM and aftermarket belts.
