Construction & Design

Manufactured from premium billet aluminum using CNC machining, this pulley offers exceptional precision and strength to withstand the demands of high-performance supercharging. The black electrophoretic coating provides uniform corrosion protection and a durable finish that resists wear even in harsh environments. Its 5-rib serpentine design matches the factory belt profile, ensuring smooth operation and reliable belt tracking without the need for additional modifications or adapters.

Performance & Sound

By reducing the pulley diameter from stock size, this Hellcat supercharger pulley increases the supercharger’s rotational speed, resulting in higher boost pressure. This boost translates into improved engine responsiveness, increased horsepower, and enhanced torque delivery across the RPM range. While the pulley itself does not directly alter exhaust sound, the added power and boost can contribute to a more aggressive engine note during acceleration.

Installation & Fitment

Designed as a direct replacement for the factory pulley, installation is straightforward for experienced technicians or knowledgeable enthusiasts. Professional installation and tuning are strongly recommended to optimize performance gains and maintain engine reliability. This pulley fits a wide range of Mopar vehicles equipped with 5.7L, 6.1L, 6.2L Hellcat, and 6.4L HEMI engines from model years 2000 through 2026, including Dodge Challenger, Charger, Durango, as well as other Chrysler, Jeep, and Ram models.
