ACL Race Series tri-metal bearings are manufactured to strict tolerances. CNC machining operates to micron precision before metrological inspection of diameter, thickness, and width. ACL Race Series tri-metal bearings ensure reliable and consistent fit in your performance engine. ACL Race Series tri-metal bearings comprise 4 layers:

• Outer SAE1010 steel
• Copper alloy 0.3mm
• Nickel 0.0001mm
• Copper alloy 0.013 to 0.018mm

This material strategy combined with manufacturing processes makes ACL Race Series tri-metal bearings more resistant to power increases, torque boosts, and higher RPMs. Compression resistance of ACL Race Series tri-metal bearings provides reliability to your engine even with turbo or supercharger prep, or high-RPM performance engines.

Since 1960, KING RACING designs and manufactures high-performance / quality bearings. Beyond ultra-high-performance machinery, King Racing relies on simulation software to analyze thermodynamics, dynamics, and elastohydrodynamics of their bearings. KING RACING tri-metal bearings are produced in pMax Black, a tri-metal alloy 24% more resistant than all existing tri-metal bearings.

KING RACING bearings comprise 3 to 4 layers (by application):

Outer: Steel Intermediate: Lead-bronze Inner: White metal alloy with high copper content Anti-friction coating: contains lubricant and ceramic additives
