- Meets and exceeds SFI 1.5 safety standards for racing applications
- Optimized for forced induction and high-performance driving conditions
Construction & Design:
This flywheel is crafted from high-grade forged steel, utilizing a 4140 steel plate that undergoes a rigorous stamping process involving 2000 tons of pressure at 1260 degrees. This ensures a robust, wear-resistant surface capable of withstanding the stresses of aggressive driving and racing environments. The one-piece ring gear design eliminates potential weak points found in multi-piece assemblies, enhancing durability and reliability.
Precision CNC machining and dynamic balancing guarantee smooth operation and compatibility with OEM clutch components. The lightweight construction reduces the flywheel’s mass by more than half compared to stock units, allowing the engine to accelerate more rapidly and improve throttle response without compromising drivability or clutch engagement quality.
Installation & Fitment:
The Competition Clutch Ultra Lightweight Flywheel is a direct bolt-on replacement for the 2005–2010 Scion tC and 2008–2015 Scion xB (xB2) models equipped with the 2AZ-FE engine. Installation requires standard clutch removal procedures and can be performed by experienced enthusiasts or professional technicians. No modifications to the transmission or engine components are necessary, and it works seamlessly with both OEM and aftermarket clutch kits.
