Clevite MS-2209P High Performance Main Bearing Set

The Clevite MS-2209P 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, ensuring optimal lubrication under extreme conditions.

Key Features:

• P-Series high performance design with unique core part numbers
• Full grooved upper shells for maximum oil flow to rod bearings
• High crush construction for maximum bearing retention
• Reduced overlay thickness to prevent overlay fatigue
• Maximum eccentricity for narrowed bearing contact patterns
• Hardened steel back for added strength and fretting resistance
• TriMetal bearing construction for legendary durability

Important Notes:

• Requires thrust washer set (sold separately - use with Part# TW-606S)
• Thrust washers are NOT included with this bearing set
• Designed for applications requiring high oil flow to rod bearings
• Ideal for extremely high RPM applications and engines experiencing rod bearing oil starvation

The P-Series bearings are Clevite's oldest and most proven high-performance bearing line, featuring the greatest amount of eccentricity among their performance bearing options. These bearings excel in applications where rod bearing oil starvation is a concern, typically indicated by polishing and smearing of bearing surfaces with possible discoloration at the axial center. The full groove design in these main bearings prioritizes oil delivery to connecting rod bearings, making them ideal for high-RPM racing engines that demand maximum lubrication.
