King Racing Connecting Rod Bearing Set – Subaru EJ20 / EJ22 / EJ25 (Incl. Turbo)

Engineered for high-performance and racing applications, the King Racing XPC Connecting Rod Bearing Set is a proven choice for Subaru EJ20, EJ22, and EJ25 engines, including turbocharged variants. Commonly used in circle track, drag racing, and off-shore applications, these bearings are optimised for steel crankshaft configurations.

Part of King’s XPC Series, this bearing set features the advanced pMaxBlack™ overlay, providing increased hardness and fatigue resistance. It is topped with pMaxKote™, a ceramic nano-composite polymer coating that enhances wear and seizure resistance without altering the bearing's original wall thickness or precision tolerances.

• Bearing Length: 16.5 mm (0.650 inch)

• Wall Thickness: 1.501 mm (0.0591 inch)

• Coating Technology:

  • pMaxBlack™ for increased hardness and fatigue resistance

  • pMaxKote™ ceramic nano-coating for improved wear and seizure resistance

• Material Compatibility: Optimised for steel crankshafts

• Configuration: Connecting rod bearing set – suits 52mm journal

Bearing Sizes Available:

• STD (Standard): For standard journal and housing sizes with factory tolerances

• STDX (Standard Extra): Slightly reduced clearance compared to STD for tighter tolerance applications

• 0.25mm Undersize: For crankshafts ground 0.25mm undersized (typically 0.010")

• 0.026mm Extra Clearance: Provides increased oil clearance for high-performance builds

• 0.5mm Undersize: For crankshafts ground 0.50mm undersized (typically 0.020")

Proper bearing selection is critical to maintaining correct oil clearance. Always measure crankshaft and housing dimensions carefully and consult engine build specifications when choosing bearing sizes.
