Product Details

Maximize reliability and performance with the King MB5304XP Main Bearing Set (STD Size), engineered for Mazda B6, B6-T, ZM, B3, and B5 engines. Built with King’s race-proven pMax Black tri-metal construction, these bearings are designed for high-load, high-RPM environments—ideal for street/track Miatas and boosted builds.

The XP series bearings use a unique tri-metal pMax Black overlay combined with a hardened steel backing to deliver superior fatigue resistance and reduced wear under extreme stress. This technology ensures dependable crankshaft support, consistent oil film strength, and exceptional longevity—critical for Mazda B6 and BP-powered Miatas running naturally aspirated, turbocharged, or endurance applications.

Key advantages of the King MB5304XP include:

  • Superior Fatigue Resistance – Handles high cylinder pressures and detonation resistance.

  • Optimized Oil Clearance – Ensures stable oil film for reduced friction.

  • Race-Proven Reliability – Trusted by professional builders and grassroots racers.

  • Compatibility – Fits Mazda B6, B6-T, ZM, B3, and B5 engines.

Whether you’re rebuilding a high-mileage street engine, preparing a Miata for autocross or HPDE, or building a turbocharged track monster, the King MB5304XP STD Main Bearing Set gives you the confidence to push harder without compromising reliability.
