Clevite CB451P30 P-Series Connecting Rod Bearings .030" Undersize

The Clevite CB451P30 P-Series connecting rod bearings are engineered for high-performance and high-RPM engine applications where precision and durability are critical. These bearings are specifically designed for crankshafts that have been reground .030" undersize, making them ideal for engine rebuilds and performance builds.

Key Features:

• P-Series tri-metal construction with hardened steel backing for maximum strength
• Extra-thin babbitt overlay provides excellent conformability and embedability
• Higher eccentricity and high crush factor compensates for rod bore distortion at high RPM
• Precision-engineered to maintain proper oil clearance in high-revving applications
• Compatible with aluminum connecting rods featuring dowel holes in lower sections
• .030" undersize specification for reground crankshaft journals

Clevite P-Series bearings represent the original performance bearing design from the legendary Clevite 77 family. The tri-metal construction combines a copper-lead alloy layer with steel backing and electroplated babbitt metal overlay, delivering the strength needed for demanding applications while providing the critical surface characteristics of low friction and conformability. These bearings are the proven choice for engine builders working with high-performance street engines, racing applications, and any build requiring reliable protection at elevated RPM levels.
