Spectral Performance proudly carries a great selection of performance enhancements and upgrades brought to you by PERRIN. 

The PERRIN Performance Lightweight Crank Pulley w/Large Hub features billet aluminum construction and weighs just 2lbs which also makes it 1lb lighter when compared to the factory crank pulley. This crank pulley has been designed to help reduce the rotational mass of the crankshaft which will provide less resistance for the motor to turn. This will increase the horsepower, torque, all while improving the overall throttle response. 

Additionally, this is a performance upgrade you can perform without having to perform a tune or ECU recalibration, however, a proper tune or calibration can optimize the power and potential of this crank pulley for more gains. The PERRIN Lightweight Crank Pulley will come in an anodized finish with an engraved PERRIN logo to also upgrade the overall engine bay appeal. A great component for enthusiasts with weekend show cars, but with the performance delivery for track-dedicated race cars.
