MMX One Piece Crank Hub Upgrade With Capture Plate BMW S55/N55

MMR Performance One Piece Crank Hub Upgrade With Capture Plate – BMW S55/N55 – MMR20-1003FK Issues relating to the standard three-piece crank hub on the S55 & N55 engine are widely known, but these are fully addressed with the installation of the MMR Performance one-piece billet Crank Hub together with our Capture Plate for ultimate security. The OE crank hub unit’s friction plate are known to slip, causing the timing to alter enough that piston-to-valve contact can occur and, if not totally standard and within the warranty period, leaves owners with a very expensive repair bill! Features: Prevent slipping of the friction plate, avoiding timing alterations and potential costly repairs Made from billet EN36 with 0.75mm case hardening for superior strength and durability One-piece design eliminates slipping of the friction plates Additional billet aluminium Capture Plate ensures the crank bolt cannot come undone We have developed this one-piece Crank Hub together with our Capture Plate to ensure owners have complete peace of mind, whether on an untuned factory car or equally for those that wish to increase the power and torque output significantly without ever having to worry again; MMR have engineered the most comprehensive solution on the market and at one of the most compelling price points. Then for the ultimate solution, which then also removes the possibility for this crank bolt to be able to loosen with the engine’s vibrations or harmonics, we’ve engineered an additional billet aluminium Capture Plate that securely bolts over the whole head of the crank bolt, making it literally impossible for it to come undone.
