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 MMR 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 MMR one-piece crank hub, or the OE crank hub, the elongated slots ensure a perfect, secure installation, every time.
