Clevite MS-1982P-10 P-Series High Performance Main Bearing Set

The Clevite MS-1982P-10 is a high-performance main bearing set from the legendary P-Series line, engineered specifically for demanding racing and competition applications. These bearings feature maximum eccentricity design, full 360-degree grooving for enhanced oil flow to connecting rod bearings, and high crush construction for superior retention under extreme conditions.

P-Series Performance Features:

• Maximum eccentricity rod bearings to handle extreme RPM conditions and severe rod bore close-in
• Full grooved main bearing design maximizes oil delivery to rod bearings, preventing oil starvation
• High crush design ensures maximum bearing retention during high-stress operation
• Reduced overlay thickness prevents overlay fatigue and "hen tracking" under racing conditions
• Hardened steel backing provides exceptional strength and resistance to fretting corrosion
• TriMetal construction delivers legendary Clevite durability and performance

Advanced Bearing Technology:

Clevite's optimized 180-degree upper shell grooving provides the ideal balance between oil supply and bearing film strength. The upper bearing groove efficiently supplies oil to connecting rods while the ungrooved lower bearing maintains maximum oil film thickness for superior load capacity and extended service life. This design reduces horsepower loss and minimizes peak oil film pressure compared to extended groove configurations.

Application Guidelines:

P-Series bearings are ideal for engines experiencing extreme RPM-induced rod bore deformation, typically indicated by nearly full parting line contact on standard bearings. Use this series when increased oil flow to rod bearings is critical, particularly in applications showing signs of rod bearing oil starvation such as surface polishing, smearing, or discoloration concentrated at the bearing's axial center. Extra clearance versions provide an additional 0.001" clearance for select fitting and optimized bearing clearances.

Clevite Engine Parts has been the trusted choice of engine builders and racing professionals for decades, delivering precision-engineered bearings that withstand the most punishing competition environments.
