Description

MMX BMW N55/S55 One-Piece Crank Hub Kit with Capture Plate replaces the factory three-piece hub arrangement with a one-piece billet component and adds an MMX capture plate to help retain the crank bolt.

The one-piece design is intended to remove the friction interfaces within the original hub assembly, while the capture plate provides an additional mechanical safeguard against crank-bolt loosening caused by vibration and harmonics.
