Both the N55 and S55 engines are plagued by the same issue when chasing high horsepower numbers... the dreaded crankhub failure. Fortunately MMR Performance has released an upgraded version of their already stout single-piece crankhub, but this time offering a 4-pin dowelled location that locks onto the front of the crankshaft. This configuration eliminates the multi-piece crankhub with friction discs in favor of a more robust single piece crankhub. Recommended for high-powered cars over 700 Horsepower

If your engine has higher mileage, don't neglect rod bearing replacement! These bearings are sandwiched between the connecting rod and crankshaft journal and are prone to failure due to overheating, lack of lubrication, or general wear. Replace your rod bearings and prevent a spun bearing.

Starting with ACL’s high-performance bearing shells, our Race Series bearings are built to withstand extreme RPMs and stress. Utilizing a "Duraglide" tri-metal construction and a high-strength overlay plate, these bearings offer superior oiling and heat resistance for high-RPM operation.

Our WPC-treated bearings take ACL’s already impressive design and enhance it even further. The WPC treatment process strengthens and smooths the bearing surface by firing high-speed, ultra-fine particles at the bearing shells, reducing friction and improving durability. This advanced surface treatment ensures smoother operation and improved heat dissipation, which are critical for any high-performance engine.

Kit includes

Turner Motorsport WPC-Treated Race Series Rod Bearing Shells (16) Genuine BMW Connecting Rod Bolts (16) Hardware for Oil Pan & Oil Sump Oil filter Liqui-Moly Molygen 5W-40 (6L) Drain Plug Turner Motorsport Oil Reminder Sticker Oil pan gasket RedLine assembly lube (4 oz.)

The centerpiece of this MMX kit is the UK-made CNC-machined one-piece crank hub, created from billet EN36 steel that's heat-treated with a 0.75mm case hardening, making it incredibly strong and durable. Included are four aerospace precision-machined dowels that mechanically lock the hub to the end of the crank itself, plus a brand new OE bolt. Installation of these dowels is certainly not a DIY job. But, to make the job easier for the professionals, ensuring that the required crank modifications are made safely and accurately, the MMX kit also includes a full installation jig that includes a bolt-on drilling guide, a location bolt for this guide, plus an HSS rolled high-speed drill bit. Together, the single-piece design combined with the four-pin location ensures that there is simply no way that the friction plates can ever slip. With the new OE crank bolt tightened appropriately, this delivers a transformational improvement in reliability and peace of mind versus the OE version. Also included is the MMR Crank Bolt Capture Plate. This adds one additional layer of defense, preventing the crank bolt from being able to back out and loosen over time, ensuring everything is tightly held together as intended.

When it comes to optimizing the performance and longevity of your BMW N55 or S55 engine, few upgrades can rival the impact of replacing the camshaft, bearings, and gaskets. These essential components play a pivotal role in your engine's overall health and performance, and upgrading them can deliver a host of benefits, from increased power to enhanced reliability. In this article, we'll explore the advantages of investing in these critical upgrades for your BMW N55 or S55 engine. Improved Performance: Upgrading your BMW N55 or S55 engine with a new camshaft can significantly boost its performance. A high-quality camshaft can optimize valve timing, leading to improved airflow and combustion efficiency. This, in turn, results in increased horsepower and torque, providing you with a more exhilarating driving experience. If you're seeking that extra punch when you hit the gas pedal, a new camshaft is the way to go. Enhanced Durability: The camshaft, bearings, and gaskets are fundamental components of your engine's internal structure. Over time, wear and tear can cause these parts to degrade, potentially leading to catastrophic engine failure. By replacing these components with high-quality, performance-oriented alternatives, you're not only increasing horsepower but also reinforcing the engine's durability. This can help prevent costly breakdowns and extend the life of your BMW engine. Optimal Efficiency: Efficiency is a key factor in engine performance. Worn-out bearings and gaskets can lead to oil leaks and reduced engine efficiency. Replacing them ensures a tighter seal, minimizing oil leaks and maintaining the proper lubrication for all moving parts. This leads to better fuel efficiency and a smoother, more reliable engine operation, all while reducing maintenance costs in the long run. Increased Resale Value: Investing in high-quality components like camshafts, bearings, and gaskets not only enhances your driving experience but also adds value to your BMW. When it's time to sell or trade-in your vehicle, potential buyers or dealerships will recognize the value of these upgrades, making your car more desirable and potentially increasing its resale value. Kit for All N55/S55 Engines

A common issue on N54 motors is cam bearing ledges scoring due to lack of lubrication, and if left unattended can cause damage to the camshafts and increase oil consumption. These WPC-treated cam bearing ledges help prevent lubrication issues to ensure no scoring occurs on the bearing ledge or camshaft. What is WPC, you ask? WPC is a surface treatment that reduces friction and adds strength - two improvements that benefit internal engine components. Ultra-fine particles are fired at the surface at very high speeds, like shot-peening - but much, much smaller. The parts come out smoother and stronger due to thermal discharge. The two largest enemies of any high-performance engine are heat and friction - and WPC has found a way to reduce both.
