Clevite MS-1719P High Performance Main Bearing Set

The Clevite MS-1719P is a high-performance main bearing set engineered for racing and performance engine applications. This bearing set features advanced P-Series design characteristics optimized for extreme operating conditions.

P-Series Performance Features:

• Full groove design maximizes oil flow to connecting rod bearings
• High eccentricity construction narrows bearing contact patterns for reduced friction
• High crush design ensures maximum bearing retention under extreme loads
• Reduced overlay thickness prevents overlay fatigue and "hen tracking"
• Hardened steel backing provides exceptional strength and fretting resistance
• 180-degree upper shell grooving provides optimal oil film development

Engineering and Design:

Clevite P-Series bearings represent the original high-performance bearing line, developed specifically for extreme RPM racing applications. The increased eccentricity design addresses rod bearing oil starvation issues common in high-performance engines, while the full groove configuration ensures adequate oil supply to connecting rod bearings even under severe operating conditions.

The reduced overlay thickness and hardened steel backing work together to prevent common bearing failures in racing environments. High crush specification maintains proper bearing retention even when subjected to extreme cylinder pressures and crankshaft deflection.

Applications:

P-Series main bearings are specifically recommended for engines experiencing severe rod bore distortion at high RPM, typically indicated by parting line to parting line shaft contact. These bearings are ideal when increased oil flow to rod bearings is critical, or when rod bearing oil starvation symptoms such as surface polishing, smearing, or discoloration are present.

This main bearing set is designed for professional racing applications including drag racing, circle track, marine performance, and other competition uses where maximum bearing durability and oil flow are essential.
