MMX Crank hub for BMW with N55 & S55 engine

Description

The problems associated with the original three-piece crankshaft hub on the S55 and N55 engines are unfortunately well known. Fortunately, MMR Performance's machined, one-piece aluminum crankshaft hub solves these problems.

Furthermore, combining this one-piece hub with the optional MMR mounting plate ensures complete peace of mind. This plate prevents the crankshaft bolt from loosening due to engine vibrations.
