Perfect Circle CB527P20 Connecting Rod Bearing Undersize - 020

The Perfect Circle CB527P20 is a precision-engineered connecting rod bearing designed for Chrysler big block V8 engines, including 383, 400, and 440 cubic inch applications from 1958 to 1980. This P-Series bearing features .020 inch crankshaft undersize, making it ideal for engine rebuilds where crankshaft journals have been machined.

Key Features:

• Tri-metal construction with hardened steel backing, copper-lead intermediate layer, and electroplated lead-tin-copper overlay
• Higher eccentricity and crush factor designed for high-revving engines
• Suitable for heavy duty, motorsports, and street performance applications
• Extra-thin overlay design for improved heat dissipation
• Versatile replacement suitable for most OE applications

Part of the Clevite 77 performance bearing family, P-Series bearings are engineered to compensate for rod bore distortion in high-RPM applications. The tri-metal design offers increased load capacity over traditional bi-metal bearings, making this an excellent upgrade for demanding engine builds. Sold individually.
