Clevite MS-908P-10 P-Series High Performance Main Bearing Set

The Clevite MS-908P-10 is a P-Series high performance main bearing set designed for demanding racing and competition engines. This bearing set features full 360-degree grooving to maximize oil flow to connecting rod bearings, making it ideal for applications where enhanced lubrication is critical to prevent rod bearing oil starvation.

Key Features:

• P-Series high performance design with full grooved construction for maximum oil delivery
• High crush design for superior bearing retention in demanding applications
• Reduced overlay thickness to prevent overlay fatigue and hen tracking
• Greater eccentricity to narrow bearing contact patterns and improve oiling
• Legendary Clevite TriMetal bearing construction for strength and durability
• Engineered for extreme RPM applications and high-stress racing conditions

Application Guidelines:

P-Series main bearings are recommended for engines experiencing rod bearing oil starvation, typically indicated by polishing, smearing, or discoloration concentrated at the bearing's axial center. The full groove design ensures consistent oil supply to connecting rod bearings under extreme operating conditions. These bearings are ideal for competition engines where maximum oil flow takes priority over oil film thickness in the main bearings themselves.

The higher eccentricity of P-Series bearings helps narrow bearing contact patterns, which can be beneficial in applications where standard bearings show excessive contact area. For best results, contact patterns should cover approximately 2/3 to 3/4 of the bearing surface.
