Daido is the OEM supplier for Ford 2L & 2.3L Ecoboost bearings. All their are made in Japan with very strict quality control. These Daido race series bearings feature tri-metal construction for improved particle embedability compared to the OEM Aluminum based bearings without sacrificing the load carrying capability. One feature of Daido's race series bearings feature their patented "Daido Multi Boring" which results in bearings that are round and don't have the chamfer at the parting line like other brands that results in an additional leak path so this feature results in increased oil pressure in engines with Daido race series main bearings.
