ACL Race Series tri-metal bearings are made to exacting tolerances. CNC machining works to the micron, followed by metrology checks on the diameter, the thickness and the width of every ACL Race Series tri-metal bearing. That is how these bearings give a reliable, consistent fit in your performance engine. They are in fact built up from 4 layers:

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

This choice of materials, combined with the manufacturing processes, makes ACL Race Series tri-metal bearings stronger against increases in power, torque and engine speed. Their compression strength keeps your engine reliable even on heavily boosted turbo or supercharger builds, or on sharp engines running high rpm.
