ACL Race Series tri-metal bearings are manufactured to strict tolerances. CNC machining is carried out to the micron before a metrology check of the diameter, thickness and width of the ACL Race Series tri-metal bearing. This is how ACL Race Series bearings ensure a reliable and consistent fit in your performance engine. ACL Race Series tri-metal bearings are actually made up of 4 layers:

• SAE1010 steel on the outside
• 0.3mm copper alloy
• 0.0001mm nickel
• Copper alloy from 0.013 to 0.018mm

This material strategy, combined with the manufacturing process, makes ACL Race Series tri-metal bearings more resistant to increases in power, torque or engine speed. The compression resistance of ACL Race Series tri-metal bearings brings reliability to your engine, even with turbo or supercharger builds running high boost, or high-revving engines.
