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!

Unlike traditional BMW engines, modern engines, like the B48 and B58, use a volume-flow-regulated oil pump. Instead of providing a consistent volume of oil, these new systems control oil supply at each individual operating range.

This Control Valve Solenoid is a critical component in the volume-flow-regulated oiling system. This piece seamlessly adjusts the oil pressure based on inputs from the DME. In the event of failure, this means the engine oil supply system may become restricted.

Thankfully, Bremmen Parts offers this high-quality, OE replacement Control Valve Solenoid at a fraction of Genuine price. Built with durability and fitment in mind, this component is an exact fit for your BMW.
