ACL Race Series Trimetal Bearings are manufactured to exacting tolerances. Numerical control machining takes place in microns before metrology control of the diameters, thickness and width of the ACL Race Series trimetal bearing. Thus the ACL Races Series Bearings ensure reliable and constant adjustment in your performance engine. The ACL Races Series trimetal bearings are actually made up of 4 layers:

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

This material strategy combined with manufacturing processes make the ACL Races Series trimetal bearings more resistant to increases in power, torque or even engine speed. The compression resistance of the ACL Race Series trimetal bearings allows you to provide reliability to your engine even with turbo or compressor preparations with high supercharges, or sharp engines with high rotation speeds
