Clevite MS-2248P High Performance Main Bearing Set

The Clevite MS-2248P is a high-performance engine crankshaft main bearing set designed for demanding automotive applications. This P-Series bearing set features strategic 180-degree upper shell grooving optimized to maximize oil flow to connecting rod bearings while maintaining critical oil film thickness in loaded areas.

Key Features:

• P-Series high performance design with maximum eccentricity for severe high-RPM applications
• High crush construction for superior retention and prevents bearing spin
• Hardened steel backing provides exceptional strength and fretting resistance
• Reduced overlay thickness prevents overlay fatigue and "hen tracking"
• Full groove upper shells maximize oil delivery to connecting rod bearings
• TriMetal construction for legendary Clevite strength and durability
• Engineered to handle extreme RPM conditions that cause severe rod bore close-in

Important Installation Notes:

• Requires thrust washer set TW-620S (sold separately, not included)
• Designed for engines experiencing bearing contact patterns from parting line to parting line
• Ideal for applications where increased oiling to rod bearings is critical
• Best suited for builds where rod bearing oil starvation has been an issue

The P-Series represents Clevite's original high-performance bearing technology, proven in racing and high-output street engines for decades. These bearings address the specific challenges of extreme RPM operation where standard bearings fail due to inadequate oil delivery or insufficient crush retention.
