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

The King Racing CR4125XPGC Connecting Rod Bearing Set is engineered for Subaru EJ20, EJ22, and EJ25 engines, including turbocharged variants. Designed for high-stress applications such as drag racing, circuit racing, and off-shore performance, this bearing set is optimised for use with steel crankshafts and built to handle extreme loads and RPM.

This XPC Series bearing features King’s exclusive pMaxBlack™ overlay, which provides increased hardness and fatigue strength. It is finished with pMaxKote™, a ceramic nano-composite polymer coating that enhances wear and seizure resistance without altering critical wall thickness or bearing geometry.
