Clevite MS-2269P-.75MM High Performance Main Bearing Set

The Clevite MS-2269P-.75MM is a high-performance main bearing set featuring P-Series design engineered for competition engines and extreme performance applications. This .75mm undersize bearing set delivers maximum oil flow to connecting rod bearings while providing superior retention characteristics for demanding racing conditions.

P-Series Performance Features:

• Full-groove design maximizes oil flow to rod bearings for high-RPM applications
• High crush design ensures maximum bearing retention under severe loads
• Reduced overlay thickness prevents overlay fatigue and "hen tracking"
• Hardened steel back construction provides added strength and fretting resistance
• Greater eccentricity narrows bearing contact patterns for optimized performance
• Engineered specifically for extreme RPM conditions that cause severe rod bore distortion

Advanced Bearing Technology:

Clevite P-Series main bearings utilize a 180-degree upper shell groove configuration, proven through extensive testing to provide optimal bearing performance. The upper shell supplies oil to connecting rods while the ungrooved lower shell develops a thicker oil film for improved load capacity and bearing life. This design prevents oil starvation to rod bearings, which typically manifests as surface polishing, smearing, and discoloration concentrated at the bearing's axial center.

Applications:

Ideal for competition engines experiencing extremely high RPMs, particularly where severe rod bore close-in is indicated by nearly full parting line contact. Best suited for builds requiring higher eccentricity to narrow bearing contact patterns and increase connecting rod oiling. Compatible with crankshafts requiring .75mm undersize main bearings.

Clevite's legendary TriMetal construction provides the durability and strength demanded by professional engine builders and racers worldwide.
