ACL Race Series tri-metal bearings are manufactured to exacting tolerances. CNC machining is carried out to micron precision before the diameters, thickness and width of the ACL Race Series tri-metal bearing undergo metrology inspection. This ensures the ACL Races Series bearings provide a reliable and consistent fit in your performance engine. The ACL Races Series tri-metal bearings actually consist 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 processes, makes the ACL Races Series tri-metal bearings more resistant to increases in power, torque or engine speed. The compression resistance of the ACL Race Series tri-metal bearings ensures reliability for your engine, even with turbo or supercharger set-ups running high boost, or high-revving engines.
