ACL Race Series tri-metal bearings are manufactured to tight tolerances. CNC machining is carried out to the micron, before metrology control of the diameters, thickness and width of the ACL Race Series tri-metal bearing. ACL Race Series bearings therefore give a reliable and consistent fit in your performance engine. ACL Race Series tri-metal bearings are in fact made up of 4 layers:

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

This material strategy, combined with the manufacturing processes, makes ACL Race Series tri-metal bearings more resistant to increases in power, torque and engine speed. The compressive strength of ACL Race Series tri-metal bearings brings reliability to your engine, even on turbocharged or supercharged builds running high boost, or sharp engines running high rpm.
