ACL Race Series tri-metal bearings are manufactured to strict tolerances. CNC machining is carried out to micron accuracy, followed by metrology checks of the diameter, thickness and width of each ACL Race Series tri-metal bearing shell. This is how ACL Race Series bearings deliver a reliable, 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 strength of ACL Race Series tri-metal bearings gives your engine reliability even with high boost turbo or supercharger builds, or high revving engines.
