Clevite MS-1775P-.75MM High Performance Main Bearing Set Oversize

The Clevite MS-1775P-.75MM is a high-performance engine crankshaft main bearing set designed for demanding applications. This P-Series bearing set features .75mm oversize construction for modified or resurfaced crankshafts, delivering the durability and oil flow characteristics required in racing and performance engines.

P-Series Performance Design:

• Full groove design maximizes oil flow to connecting rod bearings
• High crush construction ensures maximum bearing retention under extreme loads
• Reduced overlay thickness prevents overlay fatigue and "hen tracking"
• Greater eccentricity helps narrow bearing contact patterns for optimal performance
• Hardened steel backing provides exceptional strength and fretting resistance

Technical Features:

• TriMetal bearing construction with lead-tin-copper overlay
• 180-degree groove in upper main shells for optimal rod oiling
• Ungrooved lower shells maintain maximum oil film thickness
• .75mm oversize for machined crankshafts
• Engineered for high RPM applications and severe duty cycles

P-Series bearings excel in applications where rod bearing oil starvation is a concern or where extremely high RPMs cause severe rod bore distortion. The full-groove upper shell design ensures connecting rods receive adequate lubrication even under the most demanding conditions. High crush levels maintain positive retention in the bore, while the reduced overlay thickness resists fatigue cracking. These bearings are ideal for racing engines, high-output street performance builds, and any application requiring maximum oil delivery to rod bearings.

Clevite engine bearings are trusted by engine builders worldwide for their precision manufacturing, consistent quality, and proven performance under extreme conditions.
