10-Rib 3.47in Supercharger Drive Pulley

The Vortech Charger 10-Rib Supercharger Pulley is a 3.47-inch diameter pulley designed to enhance the efficiency of your Vortech supercharger. It is CNC-machined from 6061 T-6 billet aluminum with a black anodized finish for durability. This pulley increases the surface contact with drive belts, helping to limit power-robbing belt slip.

By upgrading to this 10-rib pulley system, you can reduce belt slippage and ensure your vehicle operates at maximum efficiency. The diameter of the supercharger drive pulley can also be altered to increase or decrease boost output, allowing you to fine-tune your power level. This product comes with a three-year warranty.
