Turner Motorsport WPC-Treated Race Series Rod Bearing Set - N52/N54/N55/S55

What's better than using standard connecting rod bearings in your next engine build? Using Turner Motorsport WPC-treated Race Series bearings!

Turner's process begins with ACL bearing shells. Designed with high performance in mind, ACL's Race Series bearings feature "Duraglide" tri-metal construction and an increased-thickness, high-strength overlay plate for improved oiling during high-RPM operation. ACL bearings are manufactured to exact OEM tolerances using micron-level precision machining for maximum accuracy and perfect fitment. Unlike many OEM and performance bearing shells, no flash plating is applied to ACL's Race Series rod and main bearings, further improving bearing retention and minimizing heat transfer. In short, Turner's foundation is the ultimate performance bearing—engineered for friction protection, reduced heat transfer, and improved oiling during all facets of engine operation.

Despite offering near-perfect wear and friction resistance, the engineers at Turner Motorsport saw an opportunity to further improve ACL'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.

Features & Benefits:

• ACL Race Series Bearing Shells: Designed for high-performance engines, featuring "Duraglide" tri-metal construction.
• Improved Oiling: Increased-thickness, high-strength overlay plate ensures better oil flow during high-RPM operation.
• Precision Fitment for Your Engine: Manufactured to exact OEM tolerances with micron tolerance machining for maximum precision.
• Smooth Surface: Our WPC-treated bearings are free of flash plating, improving bearing retention and heat transfer.
• WPC-Treatment: Reduces friction and enhances strength using ultra-fine particles fired at high speeds.
• Smoother and Stronger: WPC treatment smooths the surface and strengthens the components through thermal discharge.
• Enhanced Friction Protection: Ideal for reducing heat and friction, the two primary threats to high-performance engines.
