BMW OEM N54 8-Bolt DCT Dual-Mass Flywheel – 2009 BMW 335i (PN 21207593469)

This flywheel is engineered specifically for BMW N54 engines equipped with an 8-bolt crankshaft and is designed to function seamlessly with transmissions that use a pilot bearing located on the input shaft.

Unlike the factory flywheel, which utilizes a steel nipple pressed directly into the flywheel, this design relocates the steel nipple into a separate pilot bearing assembly. By doing so, the nipple is able to rotate freely rather than remaining fixed, reducing friction and heat during operation.

This improved configuration helps minimize premature wear, lowers the risk of nipple or flywheel failure, and in theory extends the overall service life of both components. The result is a more durable and reliable solution for high-performance and OEM-replacement applications where longevity and proper drivetrain alignment are critical.

Precision-machined and built for exact fitment, this flywheel is ideal for 2009 BMW 335i N54 platforms requiring an 8-bolt crank flywheel solution.
