Clevite MS-979P Engine Crankshaft Main Bearing Set with 3.567" Flanged Bearing

The Clevite MS-979P is a high-performance main bearing set designed for demanding engine applications. This set includes a 3.5670-inch flange diameter flanged bearing and features engineered oil distribution for optimal lubrication and bearing life.

Advanced Bearing Design:

This main bearing set utilizes proven bearing technology that maximizes oil film thickness for superior protection. The upper main shells feature a 180-degree oil groove design that efficiently supplies oil to connecting rod bearings while maintaining optimal load-carrying capacity. The lower shells are ungrooved, allowing the crankshaft to develop a thicker protective oil film for improved durability and performance.

P-Series Performance Features:

• High crush design for maximum bearing retention in performance applications
• Reduced overlay thickness to prevent overlay fatigue
• Hardened steel backing for added strength and fretting resistance
• Engineered eccentricity for controlled bearing contact patterns
• Full groove configuration to maximize oil flow to rod bearings

Application Notes:

P-Series bearings are ideal for high-RPM engines where maximum oiling to rod bearings is critical. The increased eccentricity helps narrow bearing contact patterns and prevents rod bearing oil starvation. These bearings are specifically engineered for performance engines requiring superior retention characteristics and enhanced oil delivery systems.

This is a genuine Clevite engine bearing set, manufactured to exacting tolerances for reliable performance in both street performance and racing applications.
