The eccentric shaft is an important component of BMW's Valvetronic system, a form of variable valve lift control. If the teeth on the gear or the lobes have worn out, this can result in improper valve lift, decreased or abnormal performance, and even damage to cylinder head components. Replace your eccentric shaft with this high-quality part from OEM Febi to restore performance and eliminate valve lift issues without the marked-up price of a Genuine BMW eccentric shaft.

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.)

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.

Rocker arms work in conjunction with your camshafts and valves, applying pressure from the camshaft to open and close your intake and exhaust valves. If your rocker arm rollers have failed, this can lead to extreme camshaft damage, requiring the camshaft to be replaced. Replace your rockers whenever servicing your camshafts or replacing your hydraulic lifters to ensure long-term engine reliability.
