Product Description

The aFe Power **79-10006 Supercharger Power Pulley Kit** is engineered to elevate the performance of supercharged 6.2 L HEMI engines found in modern high-power muscle cars and trucks. By reducing the pulley diameter, this kit increases the spin rate of the supercharger, resulting in an estimated **+1.5 PSI of additional boost** when paired with proper tuning. The result is more power, sharper throttle response, and a more aggressive driving feel.

Built from high-strength **6061-T6 billet aluminum** with a **17-4 stainless steel hub**, the pulley is both lightweight and rugged. The black anodized finish gives it a refined look under the hood. Installation requires some mechanical skill and specialized tools for pulley removal, but it reuses the factory belt and mounting setup. After installing, tuning is strongly recommended to optimize performance gains and ensure safe operation.
