ACL - 5M1144H-STD

ACL Race Series 5M1144H-STD Trimetal Crankshaft Bearing Set, OEM Size

ACL Race Series trimetal bearings are manufactured to exacting tolerances. CNC machining is performed to micron precision before metrological inspection of the diameters, thickness, and width of the ACL Race Series trimetal bearing. This ensures a reliable and consistent fit 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
- 0.013 to 0.018mm copper alloy

This material strategy combined with the manufacturing processes makes the ACL Races Series trimetal bearings more resistant to increases in power, torque or engine speed. The compressive strength of the ACL Race Series trimetal bearings ensures reliability for your engine, even with turbo or supercharger setups, high boost pressures, or high-performance engines operating at high RPMs.
