Upgrade your engine build with Turner's WPC-treated Race Series Bearings, engineered for serious performance enthusiasts. Starting with ACL’s high-performance bearing shells, these 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.

Key Features:

Duraglide Tri-Metal Construction: ACL's Race Series bearings feature a high-strength overlay for enhanced performance. Optimized Oiling: Designed to promote better oil flow during high-RPM conditions. Precise Fitment: Manufactured with OEM-level precision using micron tolerance machining. WPC-Treated for Strength: Surface treatment adds strength and reduces friction for improved engine performance. No Flash Plating: Allows for better heat transfer and bearing retention. Thermal Discharge Process: Smoother, stronger components through WPC’s unique thermal discharge technology. Enhanced Heat and Friction Resistance: Built to combat the biggest enemies of high-performance engines. Don’t settle for standard bearings—choose Turner Motorsport WPC-treated Race Series Bearings for the ultimate engine performance upgrade. Perfect for your next engine rebuild or rod bearing service!

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.
