This is the VMS Racing version of the JDM (Japan Spec) Honda Civic Type-R Crank Pulley, which is a special design pulley that was used in the JDM Type-R that were for track use. The original JDM Crank Pulley has a slight under drive and is of lighter mass because it eliminates the A/C pulley.
THIS NEW VMS RACING VERSION GOES ONE STEP FURTHER BY PUTTING LIGHTENING HOLES IN ITS PULLEY TO MAKE IT EVEN LIGHTER THAN THE OEM TYPE-R PULLEY!!
This pulley will provide even quicker response of the engine than the OEM Type-R pulley will because of its lower weight! It fits Honda B16, B18 and B20 DOHC VTEC Engines (except B20A). Please Note: This pulley will disable your A/C and might require a shorter belt depending on the application... It weighs just 9.8 ounces!
