Issues relating to the standard three-piece crank hub on the S55 engine are widely known, but these are fully addressed with the installation of the MMR Performance one-piece billet crank hub and capture plate. The OE units 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! We know of this problem only too well, having experienced this issue twice ourselves, so we were committed to developing a product that would ensure owners of standard power outputs have complete peace of mind, as much as those that wish to increase the power and torque output without having to worry; MMR have engineered the most comprehensive solution on the market and at one of the most compelling price points. The MMR Performance one-piece crank hub is machined from billet EN36 that's been heat-treated with a 0.75mm case hardening, making it incredibly strong and durable. The one-piece design ensures the friction plates can't slip and with a new crank bolt tightened appropriately, this alone delivers a substantial improvement in reliability versus the OE version. For the ultimate solution, which then also removes the possibility for this bolt to be able to loosen, we've engineered an additional billet aluminium capture plate that securely houses the whole head of the crank bolt, making it impossible for it to come undone. Careful design has also allowed us to develop a solution that's easy to install compared to some other products as there's no drilling or modification required to the OE crankshaft, which saves you time and ultimately money, too. The MMR crank hub kit is available in two forms, with either our one-piece crank hub, or our one-piece crank hub together with our billet capture plate, please select from the product option below before ordering.Shipping Notes

100% Cotton Pillows .
Color: White, Size: Queen Size Set of 2, Color: White, Size: Queen Size Set of 2
These pillows feel soft and fluffy without being too flat. They provide nice support for the neck and feel comfortable whether sleeping on your side or back. After several nights of use, they still keep their shape well and don’t feel too warm during the night. The set comes with two pillows, which makes it really practical for the bed.

Luxury Comfort and Perfect Support – Best Pillows Ever!
Color: White, Size: King Size Set of 2
I recently purchased the Serta Hotel collection Pillows White Goose Feather Down Fiber Gusseted, and I couldn’t be happier with my choice! These pillows are the perfect balance of softness and support — plush enough to feel luxurious, yet firm enough to keep my neck properly aligned all night. The gusseted edges really make a difference, helping the pillow hold its shape and look full even after weeks of use.
The quality of the materials is excellent — the outer cover feels smooth and breathable, and there’s no feather poking out like with cheaper options. I also appreciate that they fluff back up easily after use, making the bed look hotel-perfect every morning.
If you’re looking for comfortable, high-quality pillows that provide great value for the price, I highly recommend these. They’ve truly improved my sleep!

Good quality pillows
Color: White, Size: Queen Size Set of 2
These are very soft and supportive as advertised. W find them a little too thick for my taste (why I only gave 4 stars), but personal preference is very subjective with pillows. They are well made and high quality, and am happy with my purchase.

Overall, not that comfortable!
Color: White, Size: Queen Size Set of 2
Only okay. I find these pillows to be heavy, and not very conforming. Overall, not that great.

goose down pillows.
Color: White, Size: King Size Set of 2
Since receiving them, these king-size white goose down pillows have truly transformed my sleep. They are incredibly soft and fluffy to the touch, so plush it's hard to believe they hold their shape. Sleeping on them is like lying on a cloud.
The 100% cotton cover adds extra comfort: it feels cool to the touch, breathes well throughout the night, and helps me maintain a comfortable temperature while I sleep. Furthermore, the "reinforced fiber" structure is noticeable: after several weeks of use, the pillows retain their support; they don't clump or lose their shape, ensuring consistently good rest.
I find they have the ideal balance between firmness and softness: firm enough to support my neck and head, yet plush enough to adapt to my posture without creating pressure. This has improved my nights; I sleep more soundly and wake up with less stiffness in my neck.
In short: these pillows combine luxury, comfort, and durability. If you're looking to improve your sleep quality with soft, firm, and breathable pillows—especially in king size—these are perfect. Definitely one of the best investments you can make for better sleep.
