Perfect Circle CB831P10 Connecting Rod Bearing Ford 351W .010" Undersize Tri-Metal

The Perfect Circle CB831P10 is a P-Series connecting rod bearing designed for Ford 351W engines, featuring .010 inch crankshaft undersize and tri-metal construction. This bearing is made in the USA and represents the legendary Clevite 77 performance bearing technology now manufactured under the Perfect Circle brand.

Key Features:

• P-Series design intended for high-revving engines, especially those where high RPM causes rod bores to narrow
• Higher eccentricity and high crush factor to compensate for bore distortion, built on hardened-steel backings with extra-thin overlays
• Traditional TriMetal construction with high crush qualities for maximum bearing retention and reduced overlay thickness to prevent fatigue
• Superior tri-metal design incorporating a copper-lead alloy layer on precision steel backing with electroplated white metal babbitt surface layer for optimal conformability and embedability
• .010" undersize for reground crankshafts requiring precision undersized bearings

Ideal for rebuilding engines where more demanding use is anticipated, such as heavy duty, motorsports, or street performance, and suitable for most OE applications. Sold individually. This bearing provides a reliable upgrade option for Ford small block engine rebuilds requiring precision components.
