King Bearings popular XP Series features the pMaxBlack™ overlay - producing superior load capacity. XP is a tri-metal Lead Bronze layered material, with a nano-scaled hardening process of Babbitt overlay that withstands 10,200 PSI load. Ideal for Circle Track, Drag Racing, off-shore, and other applications that utilize steel crankshafts.
Subaru’s EJ and FA engines have been central to the brand’s success, powering everything from daily drivers to high-performance rally cars. However, like any high-performance engine, the EJ and FA series come with their unique set of challenges—particularly in oil delivery and reliability under extreme conditions. King Engine Bearings has risen to meet these challenges by designing bearings that offer enhanced performance and protection, ensuring that Subaru engines can reach their full potential.
