King Engine Bearings, a leader in high performance engine bearings, has introduced new rod and main bearings for Subaru engines in its popular XP Engine Bearings line.

The enhanced tri-metal, copper lead construction with nickel barrier of the XP Bearings features King's proprietary SecureBond advanced adhesion process which provides superior stability between the top and intermediate layers. King XP Bearings are available for Subaru applications, including rod bearings (CR4125XP - 52mm journal) and main bearings (MB5382XP - thrust in #5 position) for EJ20, EJ22, and EJ25 engines.  These new XP parts are available in STDX (.001” extra clearance), STD, and 010. The XP Bearings have a .0005" enhanced performance Babbitt overlay which provides as much as 30 percent greater load capacity than traditional bearings. They are suitable for operating temperatures of up to 350 degrees Fahrenheit. All King XP bearings feature greater rod bearing height that improves bearing to bore contact/heat transfer and reduces spin potential at high RPMs. Main bearings feature enlarged, chamfered oil holes and are ½ grooved for uncompromised lower shell load capacity. King bearings feature the closest wall tolerances in the industry (Bull’s Eye Tolerance), with all shells matched to .0001". Main and rod bearings are narrowed for large radii crankshafts
