MMX Crankhub Capture Plate Upgrade for BMW S55/N55

Prevent crank hub bolt failure in your BMW S55 or N55 engine with the MMX Crankhub Capture Plate Upgrade from MMR Performance. Designed to address the common issues associated with the standard three-piece crank hub, this capture plate ensures the OE crank bolt stays secure, preventing it from loosening during operation.

Expertly machined from T-6061 billet aluminum and finished with MMR’s trademark anodized gloss black coating, the capture plate completely surrounds and locks the OE crank bolt, making it physically impossible for the bolt to loosen or slip.

This crankhub capture plate is compatible with both the MMR one-piece crank hub and the OE crank hub, offering flexibility in installation. Thanks to its elongated slots, the installation is precise and secure every time. The plate can be installed without engine removal, requiring only the radiator to be dropped for adequate access, making it a straightforward upgrade.

For standard road use, this capture plate offers great protection against crank hub issues. However, for heavily modified or track-driven vehicles, pairing it with the MMR one-piece crank hub is highly recommended to completely eliminate the risk of costly crank hub failures.

Key Features:

• Single-piece design for durability and performance.
• Machined from T-6061 billet aluminum and anodized in gloss black for a premium finish.
• Fully surrounds and secures the OE crank bolt, ensuring no movement or loosening.
• Available as a complete kit with the MMR single-piece crank hub for ultimate protection.
• Installation possible without removing the engine—just drop the radiator for access.
