CFR Performance Hellcat Supercharger Boost Pulley

2000–2026 Dodge Challenger, Charger, Durango 6.2L Hellcat

Part #: HZ-7240-PBK

Overview

The CFR Performance Hellcat Supercharger Boost Pulley is a precision-engineered upgrade designed to enhance the performance of your 6.2L Hellcat engine. By replacing the factory pulley with a smaller 2.40" diameter unit, this pulley increases supercharger boost pressure by approximately 7.5 to 9 pounds, unlocking additional horsepower and torque without extensive modifications.

Compatible with Dodge Challenger, Charger, and Durango Hellcat models from 2000 through 2026, this pulley is ideal for enthusiasts seeking improved throttle response and overall engine output. It offers a direct bolt-on solution that maintains factory belt alignment and tension, ensuring reliable daily driving and high-performance use.

• Not compatible with ZPE Inc. Griptec Hellcat Supercharger Pulley Hub to ensure proper fitment

Construction & Design

This boost pulley is meticulously CNC machined from billet aluminum, providing an optimal balance of strength and lightweight performance. The precise manufacturing process ensures tight tolerances critical for high-speed supercharger applications, reducing the risk of belt slippage or premature wear.

The black electrophoretic coating enhances corrosion resistance, protecting the pulley from harsh engine bay conditions while delivering a smooth, uniform appearance. Its 5-rib serpentine design matches factory specifications, allowing for a direct bolt-on upgrade without requiring additional belt or accessory modifications.

Performance & Sound

By reducing the pulley diameter to 2.40 inches, this upgrade increases the rotational speed of the Hellcat supercharger, resulting in a significant boost pressure increase estimated between 7.5 and 9 pounds. This additional boost translates into improved throttle response, increased horsepower, and enhanced torque throughout the powerband.

While the pulley itself does not directly alter exhaust sound, the increased engine output can contribute to a more aggressive engine note during acceleration, enhancing the driving experience.

Installation & Fitment

The CFR Performance Hellcat Supercharger Boost Pulley is designed for straightforward installation on vehicles equipped with compatible 5-rib serpentine belt systems. It fits Dodge Challenger, Charger, and Durango Hellcat models with the 6.2L engine from 2000 through 2026.

Installation requires removal of the factory pulley and replacement with this upgraded unit, maintaining proper belt tension and alignment to prevent premature wear or slippage. Professional installation and tuning are strongly recommended to optimize performance gains and ensure engine reliability.
