• Single dual clamp diaphragm ensures consistent pressure across the clutch disc, enhancing reliability and longevity.
• Specifically engineered for track use, this clutch is optimized for high horsepower applications and aggressive driving styles.
• Designed to be used with Action Steel Flywheels for optimal performance and durability.
• Strictly intended for track and racing applications, this clutch is not recommended for daily street use due to its heavy pedal feel and engagement characteristics.

Construction & Design

The IRONMAN clutch kit features a meticulously engineered sintered iron puck that offers superior heat dissipation and wear resistance, ensuring consistent performance even under extreme conditions. The six-puck configuration maximizes grip and torque capacity, making it suitable for high-horsepower builds. The sprung hub assembly absorbs torsional vibrations, providing smoother engagement and reducing stress on drivetrain components. The clutch components are assembled with precision to ensure perfect fitment and reliable operation, making it a durable upgrade for serious track enthusiasts.

Installation & Fitment

This clutch kit is a bolt-on upgrade that requires basic mechanical skills for installation. It is designed to fit directly onto the factory flywheel when used with an Action Steel Flywheel, with no need for modifications or custom adjustments. Due to its track-oriented design, some drivers may find the pedal feel heavier than stock, which is typical for high-performance racing clutches. No cutting, drilling, or tuning is required, but professional installation is recommended to ensure proper setup and safety.
