King Racing Main Bearing Set – Coated for Subaru EJ20 / EJ22 / EJ25 (Incl. Turbo)

The King Racing MB5382XPGC Main Bearing Set is purpose-built for high-performance Subaru EJ20, EJ22, and EJ25 engines, including turbocharged variants. Commonly used in circle track, drag racing, off-shore and other demanding motorsport environments, this bearing set is engineered to suit steel crankshaft applications and thrust in position #5.

Part of the XPC Series, this bearing features a high-strength pMaxBlack™ overlay combined with pMaxKote™ ceramic nano-composite polymer coating, delivering outstanding wear and seizure resistance without altering the original bearing wall thickness.

It also incorporates an upgraded design with full oil grooves, SmartLug technology, and oil slots to address insufficient oil flow—common in EJ-series engines. The result is enhanced lubrication, durability, and reliability under race-level stress.
