The Action Clutch Chromoly lightweight flywheel for 2008–2015 Scion xB 2.4L (2AZ‑FE) is intended for drivers seeking faster engine response and robust thermal performance. Its heat‑treated chromoly design is tested to high RPMs and can be resurfaced to extend service life. The reduced rotational mass enhances responsiveness but may also introduce greater noise, vibration and harshness versus stock.
