Clevite MS-1596P-20 High Performance Main Bearing Set

The Clevite MS-1596P-20 is a high-performance main bearing set designed for demanding racing and performance engine applications. This P-Series bearing set features full groove design to maximize oil flow to connecting rod bearings, making it ideal for engines experiencing rod oil starvation or requiring enhanced lubrication.

P-Series Performance Features:

• High crush design for maximum bearing retention in the block
• Reduced overlay thickness to prevent overlay fatigue and "hen tracking"
• Hardened steel back construction for added strength and fretting resistance
• Full groove configuration in main shells for optimal oil delivery to rod bearings
• High eccentricity design to narrow bearing contact patterns and improve oil distribution
• Tri-Metal construction combining strength with conformability

Application Guidelines:

P-Series main bearings are ideal for performance engines where rod bearing oil starvation is a concern, typically indicated by polishing, smearing, or discoloration on rod bearing surfaces. The full groove design provides maximum oil flow to connecting rods, while the high eccentricity helps prevent the narrow contact patterns that can lead to bearing failure. These bearings work best in applications requiring increased oil flow and where higher bearing crush is needed for secure retention.

Technical Construction:

Clevite Tri-Metal bearings feature a steel backing, intermediate layer, and overlay surface designed to provide the optimal balance of strength, conformability, and wear resistance. The reduced overlay thickness in P-Series bearings specifically addresses the fatigue issues that can occur under high-load racing conditions, extending bearing life in extreme applications.
