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!

What's better than using standard connecting rod bearings in your next engine build? Using our Turner Motorsport WPC-treated bearings! Our process begins with King Engine Bearings bearing shells. Designed with performance and load capacity in mind, King's SV Series bearings feature a Lead-free, tri-metal Silver-based overlay with a Babbitt plating made to provide seizure resistance. Ideal for extreme-load engines, it serves as an OE replacement and can be employed as a sputter replacement. Despite offering great wear and friction resistance, the engineers at Turner Motorsport saw an opportunity to further improve King's bearing design with WPC surface treatment. WPC reduces friction and adds strength, vastly enhancing the durability of critical internal engine components. Ultra-fine particles are fired at the surface at very high speeds—similar to shot-peening, but on a much smaller scale. The treated parts come out smoother and stronger due to thermal discharge. The two greatest enemies of any high-performance engine are heat and friction, and WPC technology effectively reduces both.
