ACL Race Series Trimetal Bushings 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. So ACL Races Series bushings ensure a reliable and consistent fit in your performance engine. The ACL Races Series trimetal pads are actually made up of 4 layers:

- SAE1010 steel located outside

- 0.3mm copper alloy

- Nickel 0.0001mm

-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 compressive strength of the ACL Race Series trimetal bearings makes it possible to provide reliability to your engine, even with turbo or compressor preparations with high boosts, or sharp engines with high rotation speeds.
