aFe Supercharger Power Pulley Kit

2015–2023 Dodge Challenger & Charger 6.2L Hellcat

Part #: 79-10007

Overview

The aFe Supercharger Power Pulley Kit is a precision-engineered upgrade designed specifically for the 2015–2023 Dodge Challenger and Charger Hellcat models equipped with the 6.2L supercharged engine. By reducing the diameter of the supercharger pulley, this kit increases the spin rate of the supercharger, resulting in an approximate boost increase of 3 PSI. This translates into enhanced engine power and improved throttle response, making it an ideal modification for enthusiasts seeking to unlock additional performance from their Hellcat’s formidable powertrain.

Crafted for those who demand reliable, bolt-on performance enhancements, the aFe Power Pulley Kit offers a straightforward installation path to more aggressive boost levels without compromising drivability or engine longevity when properly tuned.

Key Features

Engineered for optimal performance and durability, the aFe Supercharger Power Pulley Kit includes:

• Precision CNC machined 6061-T6 billet aluminum pulley with a reduced diameter of 72.5mm (2.85”) for increased supercharger speed
• Boost increase of approximately 3 PSI ±0.5, delivering noticeable power gains
• Black hard anodized finish for corrosion resistance and a sleek appearance
• Laser-etched logo and sizing for authenticity and easy identification
• CNC machined 17-4 stainless steel hub combining 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 pulley size change
• Designed for a perfect fit and seamless integration with factory components

Construction & Design

The aFe Supercharger Power Pulley Kit is built with premium materials to ensure durability and performance under demanding conditions. The pulley is crafted from 6061-T6 billet aluminum, known for its excellent strength-to-weight ratio and resistance to deformation. This material choice ensures the pulley remains lightweight yet robust enough to handle increased rotational speeds.

The accompanying hub is machined from 17-4 stainless steel, providing superior corrosion resistance and mechanical strength. Both components undergo precision CNC machining to guarantee exact tolerances, a flawless fit, and a professional finish. The black hard anodized coating on the pulley not only enhances corrosion resistance but also adds a refined aesthetic touch under the hood.

Performance & Sound

By reducing the pulley diameter, the supercharger spins faster, increasing boost pressure by approximately 3 PSI. This boost gain translates into improved throttle response and additional horsepower, enhancing the Hellcat’s already aggressive performance profile. While the pulley kit itself does not directly alter exhaust sound, the increased boost and power output can contribute to a more pronounced engine note under acceleration.

Installation & Fitment

The aFe Supercharger Power Pulley Kit is a direct-fit upgrade for 2015 through 2023 Dodge Challenger and Charger Hellcat models with the 6.2L supercharged engine. Installation requires removal of the factory supercharger pulley, which involves special tools and mechanical expertise. Due to the nature of the modification, professional installation is recommended to ensure proper fitment and function.

Additionally, the kit requires the use of a smaller serpentine belt (Gates K100572HD) to accommodate the reduced pulley diameter. After installation, tuning is mandatory to optimize engine performance and maintain reliability with the increased boost levels.
