These pulleys allow the use of an 8 rib serpentine belt. This will eliminate any belt slip and boost loss when small diameter/high boost pulleys are used.

Please note: The price is for a single pulley only, please choose from the drop down menu to select which pulley you would require.

Pulley options available: 

  • (1) 8 rib grooved idler pulley
  • (2) smooth idler pulley
  • (1) 8 rib idler pulley conversion kit

In addition to the 8 rib supercharger pulley and prerequisites below, the minimum requirement for the conversion is our 8 rib grooved idler pulley; ideally though you would also want to run the smooth pulleys as well.

Prerequisites for the upgrade are shown below:

  • 8 rib supercharger pulley (as found in our boost upgrade kits)
  • Suitable length 8 rib belt for your application
  • Harmonic balancer which has a 8 rib supercharger pulley.

Please see our Listing for Harmonic Balancers to find one to suit your application.
