Hays Billet Aluminum Flywheel

2009–2017 Dodge Challenger / 2015–2017 Dodge Challenger SRT Hellcat

24-205

Overview:

The Hays Billet Aluminum Flywheel is a premium upgrade designed specifically for Dodge Challenger models from 2009 to 2017, including the high-performance Challenger SRT Hellcat from 2015 to 2017. This lightweight flywheel replaces the stock unit with a stronger, safer, and SFI-certified component engineered to enhance your vehicle’s throttle response and acceleration. Ideal for enthusiasts seeking improved performance, this flywheel reduces rotational mass, resulting in quicker gear shifts, smoother braking, and potential fuel economy benefits.

Built to withstand the demands of high horsepower street, race, and off-road applications, the Hays flywheel offers durability and reliability while reducing clutch wear and engine stress. It’s an excellent choice for drivers looking to maximize their Challenger’s power delivery and drivability without compromising safety or longevity.

Key Features:

This Hays billet aluminum flywheel incorporates advanced engineering and materials to deliver superior performance and durability. Key features include:

• SFI-certified for compliance with racing classes requiring SFI certification, ensuring safety and reliability under extreme conditions
• Constructed from 6061-T6 billet aluminum for significant weight reduction and excellent heat dissipation
• Forged, heat-treated steel ring gear with an optimized tooth profile for smooth and reliable starter engagement
• Replaceable 1050 heat-treated steel friction surface secured with high-grade fasteners, allowing easy maintenance without full flywheel replacement
• Designed using CAD technology for precise fitment and consistent product quality
• Reduced rotational mass improves throttle response, acceleration, and gear shifting speed
• Lower rotating mass reduces clutch wear and engine stress, contributing to longer component life
• Potential for improved fuel economy due to decreased engine load
• Enhanced braking and slowing performance thanks to lighter flywheel inertia

Construction & Design:

The Hays flywheel is expertly crafted from 6061-T6 billet aluminum, a material known for its high strength-to-weight ratio and excellent thermal conductivity. This construction not only reduces overall weight but also improves heat dissipation, helping to prevent overheating during aggressive driving or racing conditions. The steel ring gear is forged and heat-treated to withstand repeated starter engagement without wear, ensuring long-term reliability.

Precision CAD design guarantees a perfect fit for the specified Dodge Challenger models, maintaining factory tolerances and ease of installation. The replaceable steel friction surface is engineered for durability and serviceability, allowing you to replace the friction plate without resurfacing or replacing the entire flywheel, saving time and cost over the vehicle’s lifespan.

Performance & Sound

By reducing the flywheel’s rotational mass, this Hays billet aluminum flywheel delivers faster throttle response and quicker acceleration, translating to more immediate power delivery to the wheels. The lighter flywheel inertia also enables smoother and faster gear shifts, enhancing overall drivability. Additionally, the reduced mass contributes to easier braking and deceleration, improving vehicle control.

While primarily focused on performance, the flywheel’s design also helps maintain smooth engine operation without introducing unwanted noise or vibration, preserving the refined character of your Dodge Challenger’s powertrain.

Installation & Fitment:

This flywheel is designed as a direct replacement for the stock flywheel on Dodge Challenger models from 2009 through 2017, including the 2015–2017 Challenger SRT Hellcat. Installation requires standard mechanical skills and tools typical for clutch and flywheel replacement. No modifications to the engine or transmission are necessary, ensuring a straightforward upgrade process.

For optimal results, it is recommended to inspect and, if needed, replace the clutch assembly during installation. Proper torque specifications and alignment procedures should be followed to ensure safety and performance.

What's Included:

• Hays billet aluminum flywheel assembly
• Replaceable 1050 heat-treated steel friction surface pre-installed
• High-grade fasteners securing the friction plate
• Installation instructions

Ideal For:

This flywheel is ideal for Dodge Challenger owners who demand enhanced performance, durability, and safety from their drivetrain components. It is especially suited for enthusiasts engaged in street performance driving, drag racing, road racing, or off-road applications where reduced weight and improved throttle response are critical. The SFI certification also makes it a compliant choice for racers competing in classes that require certified components.

Hays delivers drivetrain performance parts—clutches, flywheels, flexplates, and related components—built to handle the street/strip life. It’s a trusted name for muscle and performance builds where stronger holding power, consistent engagement, and durability under aggressive launches matter.
