The Ultimate Fix for S55 & N55 Crank Hub Failure – Proven Reliability

The factory three-piece crank hub used on the S55 & N55 engines (F80 M3, F82/F83 M4, F87 M2 etc.) is a well-known weak point. Under load, the OE hub’s friction plates can slip, causing the timing to jump. When this happens, piston-to-valve contact is highly likely — often resulting in catastrophic engine damage and a repair bill into the thousands.

The MMX Performance One-Piece Billet Crank Hub eliminates this risk completely. Whether your engine is stock or running increased power and torque, this is the most complete and robust crank hub solution available.

Why Upgrade?

OE Hub Failure — A Known S55/N55 Weakness

The standard BMW crank hub uses a multi-piece friction design. Under higher torque (even from factory), the friction plates can slip, resulting in:

  • Timing jump

  • Potential piston-to-valve contact

  • Total engine failure

BMW’s only solution? Replace the entire assembly — and often deny warranty on modified vehicles.

One-Piece Billet Hub = No More Slip

MMX’s redesigned hub is a single, solid billet EN36 steel component, heat-treated and case-hardened. There are no friction plates to slip, meaning the hub and timing gear remain permanently locked together.

Key Features

  • One-piece billet EN36 steel hub – case hardened (0.75mm surface)

  • Eliminates slip from friction-plate design on OE hub

  • Straightforward install (no drilling for dowels required on unpinned version)

  • Optional Capture Plate prevents crank bolt loosening

  • Engine-safe solution for stock & tuned cars

  • Suitable for road, track and high-power builds

Capture Plate 

The Capture Plate is bolted over the crank bolt head and physically prevents bolt loosening from vibration or harmonics.

Benefits:

  • Locks the crank bolt in place – zero chance of it backing out

  • Ideal for high-RPM track or drift environments

  • Adds a second layer of security over the one-piece hub

Pinned vs Unpinned Version — Which Should You Choose?

MMX offers two versions of the crank hub:

Version Recommended For Notes
Unpinned Hub (this product) Stock to Stage 1 tuned cars No drilling into the crank needed.
Pinned Hub (upgrade option) High-power builds / drag / track cars Requires crankshaft drilling for 4 dowel pins.

For most customers, the unpinned version is more than sufficient.

Installation & Torque Specs

  • Follows BMW OE procedure

  • No special tools required (for unpinned hub)

  • Crank bolt torque: 100 Nm + 270° rotation (S55/N55)

Professional installation recommended.

Compatibility

BMW S55 & N55 Engines:

  • F87 M2 / M2 Competition (N55/S55)

  • F80 M3

  • F82 / F83 M4

  • Also fits other BMW models using N55 engines

You only need 64 pages to tell an amazing story.
Format: Hardcover
Before reading The Killing Joke, I've ready V for Vendetta and Watchmen. Both are other graphic novels written by Alan Moore. I had no idea what to expect, but a friend of mine did call this (in his opinion) the greatest graphic novel of all time. I think it's damn near close to it. The Good: I love Batman. Doesn't matter where he is. Nolan movies? Arkham series? Comics? They're all awesome, so of course I was gonna love Batman in this story too. The joker is also a stand out character obviously. I hate to love the joker because he's that awesomely terrible. It's amazing. This story isn't so much about Batman fighting bad guys as it is about proving the joker wrong. "All it takes is one bad day." Well does it? Batman (and Gordon) are pushed to their limits as they not only try to stop the joker, but prove him wrong. By the end of the story, you wonder who TRULY won that night. I won't give any spoilers, but the ending does make you wonder. You see what I mean? It's psychologically complex and disturbing. It really makes worry about the outcome of ALL the characters. One thing I liked from another comic, Batman: Hush, was the use of other DC characters to progress the story, but I really liked how The Killing Joke told another amazing story with less character in less pages. I also really like that short story after the end of the main story. I'm glad it was there. The Bad: There really isn't all that much bad. I mean I would have loved for it to be longer, but I still enjoyed it for what it is. That's really my only complaint. It just a little too short, and I wanted to keep on reading. Final Verdict: I don't know if it's the greatest graphic novel of all time, but I loved it and I think everyone else who reads it will love it too. I mean I read the whole thing is one sitting in less than an hour. I literally could not put the book down. BUT! There's a lot of very disturbing moments in the story, so know what you're getting yourself into. I mean the animated movie adaption for this book is rated R!

Tycho Evaluates: "Batman: The Killing Joke"
Format: Hardcover
As a big fan of Batman as a character and the DC universe, I've always thought of The Joker as my favorite villain. He's a character I've long been obsessed over, there's a lot of fascinating elements about him that have impressed and captivated me, that began with the first time I saw The Dark Knight. Heath Ledgers portrayal of the character astounded me, and inspired me to research more on the history of the character and discover how it was created, and how he's been portrayed throughout the years. One name kept coming up during my search, Batman: The Killing Joke, cited as the quintessential comic featuring The Joker. So, I went online, purchased it and read it. And...it's one of the greatest things I've ever read. There's a quote on the front cover from Tim Burton, saying that its the first comic he ever loved. I agree with that on a lot of levels, as a person who hasn't read too many comic books, I can still tell what a masterpiece this one is. The atmosphere created by the illustrations of Brian Bolland, the writing and dialogue created by Alan Moore, really made me feel like I was watching a movie. That I was experiencing a living, fluid story centered around the actions and origin of The Joker. The balance they achieved between scenes without dialogue and scenes with conversations between characters is perfect, creating beautiful build up and suspense. From Batman walking into Arkham Asylum, to the shooting of Barbra Gordon, to the reveal of the comedian transformed into The Joker. Every page of this book carries so much, accomplishing something I didn't think was possible. Giving a concrete origin to The Joker, a character that's not supposed to have a past, to be utterly mysterious and detached. It works so well though, a failed comedian who has one really, really bad day. Ruining his life and reducing him to a deranged killer obsessed with the idea that life, reality, and the human condition are just a massive joke. There's two moments in this comic that stick out the most to me, one is the moment when the comedian is told his wife is dead. There's a panel where he says nothing, then simply replies with "What?". It truly captures a moment of absolute disbelief, how a man would react to the worst news imaginable, in that he would barely react at all. Then, there's the ending. Out of respect for the sheer brilliance of the conclusion, I wont spoil it here. To wrap up my ramblings, Batman: The Killing Joke is an incredible comic that serves as quite possibly the best story featuring The Clown Prince of Crime. I recommend it to anyone who is even a cursory fan of Batman, The Joker, dark comedy, or simply superb illustration and writing. Its definitely worth the read...and the laughs. -Tycho

Great resource to refer to
Format: Paperback
I thought that I was just going to use it as a reference book but when I was reading it I was very interested and ended reading the whole thing. I learned a lot short cuts and tricks and tips. I still refer to the book all the time. Great investment for a reference.

Good Introduction
Format: Paperback
A good introduction to the basic concepts but nothing in detail. Though...there is quite a couple of grammatical errors. Scissors cannot be a singular noun (i.e. there is nothing like "a scissors")
