MMX Crank hub capture plate | BMW S55 | N55
The N55 and S55 crank bolt is susceptible to loosening due to the engine’s natural vibrations and harmonics, meaning that with just the slightest loss of torque, your timing will slip out of correct adjustment. With potentially disastrous consequences.
The MMX Performance capture plate completely surrounds and secures the head of the OE crank bolt, making it physically impossible for it to turn or loosen. Secured to either the MMX one-piece crank hub, or the OE crank hub, the elongated slots ensure a perfect, secure installation, every time.

This MMX capture plate is a great starting point to avoid the dreaded hub-slip problems for standard cars, and those not used in track conditions.
However, for complete peace of mind, and certainly when it comes to highly modified or hard-driven cars, we strongly recommend selecting the one piece crank hub plus capture plate as the only way to be 100% certain to avoid future costly failures.
