A crank hub upgrade is about keeping engine timing stable. This MMX Performance single-piece kit replaces the factory multi-piece arrangement on supported N55 and S55 engines. The unpinned hub is MMX's choice for stock or Stage 1 builds; its separate four-pin version is recommended for higher-output applications.

Key features

  • One-piece billet EN36 steel construction replaces the multi-part factory hub.
  • Heat treatment adds strength and wear resistance.
  • Unpinned installation avoids drilling the crankshaft for locating dowels.
  • Select the capture-plate configuration for added crank-bolt retention.

What's included

  • Single-piece crank hub and new crank bolt
  • Capture plate when selected

Installation and fitment notes

  • Intended for stock through Stage 1 applications. MMX recommends its four-pin hub for higher power and torque.
  • Professional installation and correct engine timing procedures are required.
  • M135i and Touring applications include non-US market vehicles. Match the chassis and engine.
