EXEDY SF04 Lightweight Flywheel

The EXEDY SF04 Lightweight Flywheel is engineered for automotive performance enthusiasts seeking optimal engine response and reduced rotational mass. Constructed from high-quality billet chromoly steel, this flywheel offers a superior strength-to-weight ratio, making it an excellent choice for light to moderately tuned vehicles used in drag racing, autocross, and rally applications.

Material and Construction

Manufactured from solid one-piece billet chromoly steel, the SF04 flywheel stands out due to its robust design. Chromoly, a blend of chromium and molybdenum, enhances the material's strength and hardness compared to standard steel or aluminum flywheels. This construction ensures durability and reliability, especially under high-stress conditions typical in competitive motorsports.

Performance Features

  • Low Weight and Inertia: The SF04 is designed to minimize weight and inertia, resulting in quicker engine response and improved throttle sensitivity.
  • Enhanced Airflow: Special design features promote better airflow, aiding in clutch cooling during intense driving scenarios.
  • Integrated Ring Gear: Unlike aluminum flywheels, the ring gear teeth are integrated into the flywheel, eliminating the risk of separation due to differing expansion rates.
  • SFI Approved: The SF04 meets SFI 1.1 certification standards, ensuring it has passed rigorous testing for safety and performance in competitive environments.

Installation Notes

While specific fitment details for the SF04 are not provided, it is essential to confirm compatibility with your vehicle prior to installation. The lightweight design is particularly beneficial for applications where rapid engine response is crucial. Proper installation is key to maximizing the performance benefits of this flywheel.

Performance Testing

The EXEDY SF04 Lightweight Flywheel is engineered to handle RPMs of 15,000 to 18,000, making it a reliable option for high-performance applications. Users can trust its durability under competitive conditions, backed by the SFI certification.
