Torque Solution Lightweight Crank Pulley Subaru Impreza, WRX, STi, Legacy & Forester

Torque Solution has designed this lightweight crank pulley not only to improve performance but to surpass the quality of the original pulley. A critical feature of the Torque Solution pulley is its increased mounting surface area between the pulley and the crankshaft. The increased surface area distributes the contact load over a larger area, eliminating the chances of the pulley spinning loose. Torque Solution constructed this crank pulley from high quality CNC machined billet aluminum to provide lightweight without sacrificing strength. The black anodized finish seals the aluminum and preserves the appearance. Most important, this lightweight pulley improves throttle response and increases acceleration by putting more horsepower and torque to the wheels.
