Weight reduction is key to making the best use of any available HP and torque. In no place on our vehicle is this more important than the rotating mass found in the engine. The PERRIN PerformanceTM Crank Pulley is 4-pounds lighter than the stock crank pulley. This reduction is equal to removing more than 100 lbs of vehicle weight! Throttle response, horsepower and torque are all increased with this easy to install product!
Perrin's crank pulley is cut from 6061T6 aluminum, anodized black and laser etched for increased belt life and a precision fit.
This part fits all 1993 & Up Impreza, WRX, & STI's, 1990 & Up Legacy Models, and all Foresters & Baja Turbo's.
