Clevite MS-2279H Performance Main Bearing Set H-Series

The Clevite MS-2279H is a high-performance engine crankshaft main bearing set from the trusted Clevite 77 H-Series line. Engineered for demanding applications, this bearing set delivers the durability and precision required for medium to high RPM engine builds.

H-Series Performance Features:

• Medium level of eccentricity for optimal oil clearance control
• High crush design ensures secure retention in the bearing saddle
• Hardened steel backing provides exceptional strength and dimensional stability
• Thin overlay construction promotes faster break-in and conformability
• Non-flash plated surface for superior seating characteristics
• Designed for crankshafts with oversize fillets

Clevite H-Series bearings are specifically developed for performance and racing applications where engine speeds exceed stock RPM ranges. The hardened steel back resists distortion under high loads, while the precision overlay material protects the crankshaft journal and accommodates minor surface imperfections. The absence of flash plating allows the bearing to seat more effectively during initial startup, reducing the risk of bearing movement and ensuring consistent oil film thickness throughout the engine's operating range.

Ideal for engine builders and enthusiasts seeking OE-quality replacement bearings with enhanced performance characteristics for street/strip, racing, and high-output engine applications.
