Genuine OEM Volkswagen Flywheel, part number 03C105266AA. This critical component is mounted to the engine crankshaft and serves to transfer rotational power from the engine to the transmission. It also stores rotational energy to smooth out engine power delivery and helps to dampen engine vibrations, particularly in the case of a dual-mass flywheel as pictured. The flywheel is located between the engine and the transmission. Weighing 6.61 kg and with a diameter of approximately 0.28 m, it is constructed from robust steel. Choosing a genuine OEM flywheel ensures precise balancing, correct material properties for high rotational forces, and effective vibration damping, which are crucial for smooth power delivery, transmission longevity, and overall drivetrain performance.
