aFe Supercharger Power Pulley Kit

2015–2023 Dodge Challenger / Charger 6.2L Hellcat

Part #: 79-10008

Overview

The aFe Supercharger Power Pulley Kit with a 2.65-inch hub is a precision-engineered upgrade designed specifically for the 2015 to 2023 Dodge Challenger and Charger Hellcat models equipped with the 6.2L supercharged engine. This pulley kit is ideal for enthusiasts seeking to increase boost pressure and overall engine performance without compromising reliability. By reducing the supercharger pulley diameter, the kit delivers a noticeable boost increase, enhancing throttle response and power output for a more aggressive driving experience.

Perfect for performance-minded drivers who want to extract more from their Hellcat’s supercharged powertrain, this pulley kit offers a straightforward upgrade path that complements other bolt-on modifications and tuning.

Key Features

Engineered for durability and performance, the aFe Supercharger Power Pulley Kit includes the following key features:

• Boost increase of approximately 4.5 PSI ±0.5, providing a significant power gain
• CNC machined 6061-T6 billet aluminum pulley with a diameter of 67.25mm (2.65 inches) for lightweight strength
• Black hard anodized finish for corrosion resistance and a sleek appearance
• Laser-etched logo and sizing for precise identification and quality assurance
• CNC machined 17-4 stainless steel hub combining high strength and corrosion resistance
• Includes all necessary hardware: screws, washers, and thread locker for secure installation
• Requires a smaller belt (Gates K100572HD) to accommodate the reduced pulley size
• Designed specifically for 2015–2023 Dodge Challenger and Charger Hellcat 6.2L supercharged engines

Construction & Design

The pulley is crafted from premium 6061-T6 billet aluminum, known for its excellent strength-to-weight ratio and durability under high-stress conditions. Precision CNC machining ensures a perfect fit and finish, while the black hard anodized coating provides enhanced corrosion resistance and a refined look. The accompanying hub is made from 17-4 stainless steel, a material prized for its toughness and resistance to wear and corrosion, ensuring long-lasting performance and reliability.

Every component is engineered to exacting standards, guaranteeing seamless integration with the factory supercharger assembly and maintaining optimal belt alignment and tension.

Performance & Sound

By reducing the supercharger pulley diameter, this kit increases the rotational speed of the supercharger, resulting in approximately 4.5 PSI more boost pressure. This boost increase translates to improved throttle response, quicker spool-up, and enhanced overall engine output. While the primary focus is on power gains, the increased boost can also contribute to a more aggressive supercharger whine, adding to the auditory excitement of driving a Hellcat.

Installation & Fitment

Installation requires removal of the factory supercharger pulley, which involves specialized tools and mechanical expertise. Due to the precision nature of this upgrade and the need for proper belt sizing, professional installation is strongly recommended to ensure optimal performance and reliability. Additionally, tuning is required after installation to safely accommodate the increased boost levels and maintain engine health.

This kit fits 2015 through 2023 Dodge Challenger and Charger models equipped with the 6.2L Hellcat supercharged engine.
