ACL Race Series tri-metal bearings are manufactured to strict tolerances. CNC machining is carried out to micron precision, ahead of metrology inspection of the diameters, thickness and width of the ACL Race Series tri-metal bearing. This ensures ACL Races Series bearings provide a reliable, consistent fit in your performance engine. The tri-metal bearings of the ACL Races Series 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 combination of material strategy and manufacturing processes makes the ACL Races Series tri-metal bearings more resistant to increases in power, torque or engine speed. The compressive strength of the ACL Race Series tri-metal bearings delivers reliability to your engine, even with turbo or supercharger builds running high boost, or high-revving engines.
