BMW M5X to ZF 8HP45 Flywheel / Flexplate

Upgrade your BMW M50, M52 or M54 engine for a ZF 8HP45 automatic transmission swap with this flexplate solution. Specifically for BMW M5X engines, this component provides the correct connection between the engine crankshaft and the 8HP45 torque converter.

This BMW 8HP45 flexplate is an ideal solution for E46 8HP conversions and other custom BMW projects using M50, M52 or M54 engines. 

Designed for BMW 8HP45 Swaps

When converting a BMW E46 from a manual or conventional automatic transmission to a modern ZF 8HP45 gearbox, the original flywheel setup cannot be used directly. This flexplate is designed to provide the correct interface between the BMW M5X crankshaft and the ZF 8HP45 torque converter.

The result is a clean and straightforward solution for your BMW 8HP swap, without the need to develop a custom flexplate yourself.
