Our 6 rib re-wrap idler pulley kits are designed to reduce drive belt slip in high performance applications.

They are designed to be used with our FDFI (Front Drive Front Inlet) series of supercharger kits, which features either a TVS2300 or TVS2650. There are different variants which require identification of the specific water pump and pulley setup that you have on your vehicle, there are documents available in the "Tech Guide" tab at the top of this page that will assist with identification.

Re-wrap pulley and mount may vary depending on engine variant, please enquire.
