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

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

This combination of materials and manufacturing process makes ACL Race Series tri-metal bearings more resistant to increases in power, torque or engine speed. The compression strength of ACL Race Series tri-metal bearings delivers reliable performance even with high boost turbo or supercharger builds, or high revving engines.
