The BMW N55 and S55 platforms deliver incredible performance, but their factory multi-piece crank hubs are a known weak point capable of catastrophic timing drift or total failure. The 034Motorsport 1-Piece Pinned/Unpinned Crank Hub with Crank Bolt Capture Plate is engineered as a complete, motorsport-grade solution that eliminates slip, locks in long-term reliability, and protects your engine under the highest levels of power and abuse.

Unmatched Engineering. Zero Compromise:

A Permanent Fix for the Factory Crank Hub Problem

The factory crank hub used in BMW’s N55 and S55 engines is a well-known weak point, particularly as power levels increase. The OEM design uses three individual sprocketed pieces that drive the timing chains off the crankshaft. Importantly, none of these sprockets are mechanically linked together nor to the crankshaft . They rely only on friction washers and the clamping force of the crank bolt to stay aligned.

Under higher horsepower, rapid throttle transitions, hard launches, or even completely stock operation, the friction surfaces can slip. When this happens, the timing components rotate out of alignment, causing the engine to fall out of mechanical timing. This can quickly lead to bent valves, piston-to-valve contact, or catastrophic engine failure.

A True Mechanical Solution Instead of More Friction:

The 034Motorsport 1-Piece Pinned Crank Hub replaces the entire multi-piece factory stack with a single CNC-machined billet EN36 steel unit. By combining all timing sprockets into one rigid body, every driven timing component remains physically linked, eliminating the possibility of internal hub slip.

You can configure the hub in the way that best suits your build:

Unpinned Installation

The 034 design can be installed in an unpinned configuration using the factory crankshaft with no drilling required. This setup works seamlessly with the included Crank Bolt Capture Plate, which locks the crank bolt in position and prevents any chance of bolt movement.

Pinned Installation (Recommended for Heavy Abuse/High Power)

For those who want maximum mechanical security, the hub can also be installed in a 4-pin configuration, physically interlocking it with the crankshaft. One of the key advantages of the 034Motorsport Crank Hub is that it eliminates the need for a separate hub version. You can choose pinned or unpinned using the same part.

To ensure safe and accurate drilling, the kit includes a carbide drill bit and a dedicated drill guide and alignment jig. Most competing kits only provide a high-strength steel drill bit, which wears quickly when cutting into the crankshaft.

Crank Bolt Capture Plate: The Second Layer of Defense

Machined from 6061-T6 billet aluminum and anodized for long-lasting protection, the Capture Plate surrounds and locks the OE crank bolt in place, preventing any possibility of bolt walk-out. Paired with the 1-Piece Hub, this configuration eliminates both crank bolt and crank hub slip, protecting against the most common N55/S55 timing failures.

Elongated mounting slots allow the Capture Plate to be used with both OE and 034Motorsport crank hubs, ensuring a precise and secure installation.

Built to Protect Your Engine, No Matter the Power Level:

From aggressively tuned street builds to fully track-prepped cars, the 034Motorsport 1-Piece Pinned Crank Hub and Capture Plate system is engineered to be the definitive solution for securing the crank hub. With uncompromising materials, precision engineering, and a complete installation package, this upgrade delivers the reliability and confidence your BMW deserves.

Upgrade once. Protect forever.

Superman is really SUPER!
Format: Paperback
Fans of superheroes cannot do without this collection of the earliest stories of the Man of Tomorrow. Superman is the epitome of what followed in the era of early superheroes and laid the groundwork for comics even today, as well as radio, TV and movie versions.

Nice collection
Format: Paperback
This is completely worth the money and the time to read. It's like taking a time machine to before he was famous. Man, this is not like present day stories and art. To me this is a history book for every comic book fan. Much like the Bstman Chronicles.

Exciting and fast paced
Format: Kindle
Loved the stories within stories flashbacks. It all ties in nicely in the end and leaves a cool cliffhanger. The art is fantastic and so is the sifting in of beloved Star Wars characters from the past. Good storyline to follow!

Great way to add even more depth to Black Spire Outpost
Format: Paperback
Having just visited Black Spire Outpost on Batuu, I really enjoyed learning more layers of depth and stories from there with this collection of comics. Having read "A Crash of Fate" and "Black Spire" was a great way to do that as well, but this was obviously a quicker read, and also spanned many different times and with some different characters, too. Great for readers with shorter attention spans, too! Recommended!

A great tie-in to the Disney parks
Format: Paperback
Welcome to the Black Spire Outpost on Batuu! I haven't been yet, but you may have if you've recently visited Disney World or Disney Land. There's obviously a lot of references to how the actual park looks. The cover featured the Millenium Falcon just like the actual attraction. This graphic novel tells one story focusing on one of the original characters made for the parks: Dok-Ondar. Within the big story there are four smaller tales being retold. Han Solo deals with a baby sarlacc. Greedo's ego is showcased. Hando comes in contact with the Guardians of the Whills. And, Doctor Aphra travels to the Sith Homeworld of Moraband. Each of these stories show off different aspects of the park that you can see for yourself if you go in person. This is what Star Wars does so well, making connections and building a big lived-in world. There are plenty of wonderful references. Ki-Adi-Mundi and Chirrut are just two of my favorites. Dok-Ondar is the true star of this book. He's an underworld mastermind. I give this book a 3.5/5. It's full of fun stories with connections to the park and featured characters from different eras. This definitely is a tie-in story, though.
