MMX 2018-2021 HEMI Supercharger 8 Rib Pulley Kit for Whipple Superchargers by MMX


SKU: MMX-8rib-pulleykit-18UP Category:


Built to Order!

**Includes New MOPAR Waterpump

This custom 8 rib pulley kit for Whipple supercharged HEMIs by Modern Muscle Performance / MMX is designed to provide greatly improved serpentine belt life and greater surface wrap on the supercharger pulley. This promotes more responsive boost pressures on quick acceleration due the decreased slippage at the small supercharger pulley. This kit also includes a high performance belt tensioner by American Racing Solutions to increase the total performance of the 8 rib kit.

Greatly reduce the number of serpentine belts that you go through in any period of time by changing over from a 6 rib stock kit to this 8 rib premium setup. More details coming soon!
If you have a NON-VVT vehicle please call prior to ordering!!
