DOUBLE KEYED CRANK HUB


What is a Double-Keyed Crank Hub?

Failed or spun crank hubs have been reported throughout the S55 community on a regular basis, which has lead to valid concerns of the integrity of the factory hub, bolt and sprocket assembly. If a crank hub fails or spins it will cause the engine valve timing to skip or jump, potentially causing engine damage or failure.

We have seen several of these through our workshop, we highly recommend fixing the crank hub issue for any engine that has completed over 60,000km and is used on track days or hard downshifting.

SSR's new double-keyed and two-piece crank hub has fast become known as the reliable alternative to the factory design.

Double-Keyed Locking Assembly design locks the valve timing chain sprocket and the oil pump chain sprocket together to prevent one from spinning independent of the other. The oil pump sprocket is also pinned to the crankshaft nose. This Double-Keyed design ensures the sprockets will not rotate out of position.

Two-Piece Design. The original crank hub assembly is made up of three pieces; the hub, the engine timing sprocket, the oil pump sprocket and the crankshaft bolt. The SSR Performance design combines the hub and timing sprocket into one machined piece. This ensures that as long as the bolt is properly tightened to the crank the timing sprocket is always in sync with the crank. This acts as added insurance to the double-keyed design mentioned above.

WHY DO I NEED IT?

If your BMW M3 F80, M4 F82, F83 or M2 Competition F87 S55 is track used, modified or heavily modified installing the SSR Crank Hub is highly recommended. A spun crank can lead to engine failure with repair costs in excess of $20,000 or if slightly luckier broken down until vehicle is sent back to workshop for the crank hub to be replaced anyway and the engine retimed.

The SCH (Spun Crank Hub) failure has been seen on both stock and modified S55 engines. If you are modifying your car, doing track work or driving hard then upgrading the crank hub in your S55 powered M car is a fail safe you will not regret.

NOTE: Drilling holes into the crankshaft using the supplied specialty drill bit is required to mate the locking pins with the crankshaft.

100% BULLETPROOF.

Globally we understand there is a 100% success rate of the SSR Performance Double-Keyed 4-Pin Crank Hub.

INSTALLATION:

Installation of any crank hub solution is extensive and must be carried out by highly qualified technicians only, the oil pan, valve covers, subframe, steering and suspension must be removed and re-installed. BMW-Specific specialty tools are required in order to set the engine cam and valve timing. Drilling holes into the crankshaft using the supplied specialty drill bit is required to mate the locking pins with the crankshaft.

We have done a number of these at BM Performance Centre.

WARNING: Improper installation may cause irreversible engine damage.

INSTALLATION TIPS:

  1. This is a great time to upgrade your turbos as everything is out of the way.
  2. For high output or high km builds it is also a great time to consider replacing the rod bearings, everything is out of the way and ready to go for a very quick and easy installation.
  3. Many components, bolts and hardware are single-use only, please ensure no bolts are re-used during this installation that should not be.
  4. The oil system must be primed prior to re-starting the engine due to the crankcase being opened up and pressure being released.

    This Pillow Is A Must Buy!! What Are You Waiting For?
    Size: Queen (Pack of 1)
    This is, without a doubt, the best pillow I have ever owned. One of my favorite features is the adjustable shredded memory foam fill, which allows you to customize the loft and firmness by adding or removing foam to suit your sleeping preferences. As both a side and back sleeper, I found it incredibly comfortable and supportive. The overall quality is excellent, from the materials used in the pillow itself to the thoughtful packaging. The removable cover is washable, although I personally use a pillowcase to keep it protected. I also appreciated that extra foam is included, making it easy to fine-tune the pillow over time. The difference in my sleep quality was noticeable from the very first night. I’ve been sleeping more comfortably and waking up feeling more rested ever since I started using it. Considering the quality, comfort, and customization options, I believe the $75 price point is well worth it. I am so impressed with this pillow that I plan to purchase another one in the future.

    This is a high-quality, well-designed pillow that combines softness, comfort, and adjustability
    Size: Queen (Pack of 1), Size: Queen (Pack of 1)
    I purchased the DreamyBlue Signature Adjustable Pillow for my husband because he often experiences back discomfort, and many of the pillows we had previously would become flat and lose their support over time. This pillow has exceeded our expectations. It is incredibly soft, comfortable, and comes with extra filling, which allows you to adjust the firmness to your personal preference. We really appreciated having that option. Even after extended use, the pillow has maintained its shape much better than other pillows we've owned. It provides a plush, cozy feel while still offering good support. My husband finds it very comfortable, and it has quickly become his favorite pillow. This is a high-quality, well-designed pillow that combines softness, comfort, and adjustability. I would definitely recommend it.

    Finally Found a Pillow Worth Keeping
    Size: Queen (Pack of 1)
    I genuinely feel like I’ve tried every pillow on the market. At one point, I thought Amazon was going to flag my account because I bought and returned so many pillows trying to find the right one. This is the only pillow that made the cut. The shredded memory foam filling makes a huge difference because the pillow is both soft and supportive, while still being adjustable to fit the way you sleep. It arrives extremely full and plush, and it even comes with an extra bag of fill, which honestly surprised me. I ended up removing about half of the filling to get it exactly how I wanted it. I’m a side/stomach sleeper, which can make finding a good pillow difficult since most are either too thick or too flat. This one was perfect because I could shape it exactly how I sleep. It stays cool throughout the night, has a slightly heavier premium feel, and feels much higher quality than most pillows I’ve tried. Super comfortable, supportive, and customizable. I would absolutely recommend it and would definitely buy it again

    A bit expensive
    Size: Queen (Pack of 1)
    Waited to give a review on this one because I needed several nights before I had any idea if it was as good as everyone says. I've had a real problem finding pillows lately. Either they're too soft to provide support and I wake up with a stiff neck or they're too sturdy and I wake up with a stiff neck. Contour pillows have worked best for me, but they fall under the category of too sturdy. I also toss and turn too much at night, which means I always end up in an awkward position with contour pillows. So I took a chance on an obscenely expensive pillow, and yes, that is the reason for one less star. I'd happily pay $70 for a pillow I thought was amazing and comfortable and perfect, but this one wasn't quite it. It IS comfortable. I have slept on it for a month now without it making my neck stiff, so it does actually provide a good balance between soft and sturdy. They make it easy to stuff the pillow to your preferred fluffiness and even provide extra stuffing if you need it, which adds to the degree of comfort. While the pillow does provide good neck support, I toss and turn a bit trying to find a comfortable position when I first try to sleep. The stuffing within the pillow moves around at night, most notably shifting to the side and the pillow is notably flatter now than when I first purchased it. You can fluff it out, similarly to a down pillow, but it doesn't seem to retain its shape on its own. In some ways, that's good because what it does instead is try to retain a shape that fits you. So yes, this is a really good pillow. One of the better ones you can buy. But it's really expensive for a pillow.

    Best pillow I've ever had
    Size: Queen (Pack of 1)
    I don't really write reviews but holy buckets, Batman. This pillow is legit. Back, neck, and shoulder pain is nothing new for me; I've had scoliosis since I was a kid and hyperflexibility in my neck since birth leading to frequent muscle spasms that have caused me to miss work. Guys. This pillow. It is the most comfortable pillow I've ever had. Like, my neck doesn't hurt and I genuinely didn't remember what that felt like. It's simultaneously supportive and soft and it doesn't sink in. The instructions are super clear to understand and the pillow fluffs up no problem if it gets a little flat. This is a game changer for me and I so hope anyone who buys this has the same experience.
