Clevite MS-2279P Engine Crankshaft Main Bearing Set

The Clevite MS-2279P is a high-performance engine crankshaft main bearing set designed for demanding racing and performance applications. This P-Series bearing set features full groove design to maximize oil flow to connecting rod bearings, making it ideal for engines experiencing severe operating conditions and high RPM use.

P-Series Performance Features:

• Full grooved design maximizes oil delivery to rod bearings
• High crush construction for maximum bearing retention
• Reduced overlay thickness prevents overlay fatigue and "hen tracking"
• Hardened steel back provides added strength and fretting resistance
• Greater eccentricity narrows bearing contact patterns for improved performance
• No flash plating for superior bearing seating

Ideal Applications:

• Engines experiencing rod bearing oil starvation issues
• High RPM applications requiring maximum oil flow to connecting rods
• Performance builds where narrower contact patterns are desired
• Racing engines with extreme operating conditions

Clevite P-Series bearings represent the original high-performance bearing line from Clevite, featuring unique core part numbers specifically engineered for competition use. These are not standard passenger car bearings—they're purpose-built for racing with increased eccentricity and specialized design characteristics that address the unique demands of high-performance engines.

The full groove design in P-Series main bearings ensures connecting rod bearings receive adequate lubrication even under extreme conditions, helping prevent the polishing, smearing, and discoloration that indicates oil starvation. Choose P-Series main bearings when your engine requires maximum oil delivery and proven performance bearing technology.
