Honda A-Series B-Series 0.25 King Racing Main Beairng - MB5259XP0.25
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.
