PERRIN Lightweight Crank Pulley, Black (2012-2016 Impreza & 2015-2017 Impreza WRX)

DECREASES ROTATIONAL MASS
The PERRIN Performance Crank Pulley weighs just 1.2 lbs, which is 3.7 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
Designed to look mean and fast, the PERRIN Crank Pulley has precision machined grooves which tightly sync with all OEM and aftermarket belts.

CONSTRUCTION
The PERRIN crank pulley is machined from 6061T6 billet aluminum, anodized black and laser etched for increased belt life and a precision fit.
