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.
