When you need the best, you go to a specialist—and for the best bearings, you see King Engine Bearings. King focuses on one product—bearings—and nothing else. Their innovative, race-only Xtreme Performance tri-lecular main bearings are proven track-tough to handle the ground-shaking power of your race engine. Built with enhanced tri-metal, these XP-Series main bearings layer copper lead construction with a nickel plate barrier and a lead/tin/copper babbit overlay over a steel backing in an adhesion process that provides superior stability and durability.
King's advanced control measures hit a bull's-eye, maintaining wall thickness tolerances far tighter than their competitors—an amazing +/- .0001 in.! These XP-Series' main bearings are narrowed for large radii crankshafts and feature enlarged, chamfered oil holes with full, 3/4, or 1/2 grooving for improved oiling. How many reasons do you need to use a specialist? King XP-Series main bearings deliver consistent and reliable performance with a high-load capacity, and the prognosis from the specialists is a long and happy life for your engine.
