Perrin Performance Lightweight Crank Pulley Black 2002-2014 WRX 2004-2021 STI
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.
The PERRIN Performance Crank Pulley weighs just 1.2 lbs., which is 4 lbs. lighter than the 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.
Precision machined grooves, tightly sync with all OEM and aftermarket belts. While the PERRIN Performance crank pulley fits great on all 1993 or newer Subaru boxer engines, the rear belt keeper is now minimized to make installation on 2008+ Subarus easier!
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.
