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!
