Clevite MS-1802H Performance Main Bearing Set

The Clevite MS-1802H is a high-performance engine crankshaft main bearing set from the renowned Clevite 77 H-Series line. Engineered for demanding applications, this bearing set delivers exceptional durability and reliability in medium to high RPM engine builds.

H-Series Performance Features:

• Medium level of eccentricity for optimal oil clearance control
• High crush design ensures positive retention in the housing bore
• Hardened steel backing provides superior strength and fatigue resistance
• Thin overlay construction improves conformability and embeddability
• Non-flash plated finish allows for better seating and faster break-in
• Designed for crankshafts with oversize fillets

Clevite 77 H-Series bearings are the preferred choice for performance engine builders who demand precision-engineered components. The advanced metallurgy and optimized geometry make these bearings ideal for street performance, bracket racing, and other applications where engine speeds regularly exceed stock operating ranges. The absence of flash plating promotes superior mating between the bearing and housing, reducing the risk of bearing movement and ensuring consistent oil film thickness throughout the RPM range.
