Torque Solution Underdrive Crank Pulley Kit: Porsche Boxster / Cayman / 996 / 997 With AC TS-POR-458AC

Torque Solution Underdrive Crank Pulley has been designed to improve performance by being lighter and smaller than the OEM crank pulley. This results in less engine load which in turn produces faster revs and increased throttle response. Made from high quality CNC machined 6061-T6 billet aluminum to be lightweight without sacrificing strength. The black anodized finish seals the aluminum and preserves the appearance. To complete the install we provide a new crank pulley bolt, as well as the proper serpentine belt.
