ACL Race Series trimetal bearings are manufactured to strict tolerances. CNC machining is carried out in microns, followed by metrology inspection of the diameters, thickness and width of the ACL Race Series trimetal bearing. This is how ACL Races Series bearings ensure a reliable, consistent fit in your performance engine. ACL Races Series trimetal bearings are in fact 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 Races Series trimetal bearings more resistant to increases in power, torque or engine speed. The compression resistance of ACL Race Series trimetal bearings lets you keep your engine reliable even with turbo or supercharger builds running high boost, or high revving engines.
