A true weight savings that can be felt with every blip of the gas pedal. One of our best selling parts, many thousands installed on Subaru engines around the world.
Decreases Rotational Mass
The PERRIN Performance Crank Pulley weighs just 1.2 lbs, which is 4-pounds lighter than the stock OEM crank pulley. This reduction in weight from the crank shaft is equal to removing more than 100 lbs of vehicle weight! Throttle response, horsepower and torque are all increased with this easy to install part.
Design
Precision machined grooves, tightly sync with all OEM and aftermarket belts.
Construction
The PERRIN crank pulley is machined from 6061T6 billet aluminum, anodized black or red and laser etched for increased belt life and a precision fit.
Gates Micro-V Stretch Fit Belt
Gates stretch fit belts may look like standard V-ribbed belts but inside they are dramatically different. The secret is Gates new TwistLock Technology where the strength and flexibility of advanced polyamide tensile cord is surrounded by a specially formulated adhesive that literally locks on to the cord- allowing the cord to elongate and stretch but never lose tension.
