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

Part #: HZ-7310-PBK

Overview

The CFR Performance 3.10" Hellcat Supercharger Boost Pulley is a precision-engineered upgrade designed to unlock additional power from your 6.2L Hellcat engine. This billet aluminum pulley increases supercharger speed, delivering an estimated 1.5 to 2.5 pounds of extra boost pressure over the factory setup. Ideal for Mopar enthusiasts and performance builders, it offers a reliable, bolt-on solution to enhance throttle response, horsepower, and overall engine performance without extensive modifications.

Compatible with a broad range of Chrysler, Dodge, Jeep, and Ram vehicles equipped with 5.7L, 6.1L, and 6.4L HEMI engines from 2000 through 2025, this pulley integrates seamlessly with the factory 5-rib serpentine belt system. Whether you’re upgrading a Dodge Challenger, Charger, Durango, or other Mopar models, this pulley is engineered to maximize your supercharger’s potential.

Key Features

Designed for durability and performance, the CFR Performance Hellcat Supercharger Boost Pulley includes these standout features:

• 3.10" (78.74mm) pulley diameter to increase supercharger rotational speed and boost pressure
• Estimated boost gain of 1.5 to 2.5 pounds, depending on engine setup and modifications
• Compatible with 5.7L, 6.1L, and 6.4L HEMI engines from model years 2000 to 2025
• CNC machined from high-strength billet aluminum for superior strength and precision
• Durable black electrophoretic coating (e-coating) for corrosion resistance and a sleek finish
• Designed to work with factory 5-rib serpentine belt systems for straightforward installation
• Compatible with Metco Motorsports Hellcat Supercharger Pulley Hub (not compatible with ZPE Inc. Griptec hubs)

Construction & Design

This boost pulley is meticulously CNC machined from billet aluminum, ensuring exceptional dimensional accuracy and structural integrity. The billet construction provides a lightweight yet robust component capable of withstanding the increased rotational forces generated by higher boost levels. Its black electrophoretic coating offers excellent corrosion protection, maintaining the pulley’s finish and performance even under harsh engine bay conditions.

The pulley’s 5-rib serpentine design guarantees a perfect fit with factory belt systems, preserving reliability and minimizing installation complexity. This precision engineering ensures consistent performance and long-lasting durability for your Hellcat supercharger setup.

Performance & Sound

By reducing the pulley diameter to 3.10 inches, this upgrade increases the supercharger’s rotational speed, resulting in a measurable boost pressure increase of approximately 1.5 to 2.5 pounds. This additional boost translates to improved engine responsiveness and enhanced horsepower potential, allowing your Hellcat engine to deliver stronger acceleration and more aggressive performance.

Alongside performance gains, users may notice a subtle increase in supercharger whine, adding an aggressive auditory character that complements the enhanced driving experience without being intrusive.

Installation & Fitment

The CFR Performance Hellcat Supercharger Boost Pulley is designed for direct fitment on select Chrysler, Dodge, Jeep, and Ram vehicles equipped with 5.7L, 6.1L, and 6.4L HEMI engines from 2000 through 2025. Installation involves removing the factory pulley and replacing it with this upgraded unit while maintaining compatibility with the stock 5-rib serpentine belt system.

Professional installation and tuning are strongly recommended to optimize performance gains and ensure engine reliability following the boost increase. This ensures your vehicle runs safely and efficiently with the new pulley installed.

What's Included
