Engine & Performance Warehouse CB684P8020 Clevite P-Series Connecting Rod Bearing Undersize - Set 020

This connecting rod bearing set features Clevite's proven P-Series tri-metal design, engineered for high-performance and heavy-duty engine applications. The set includes 8 individual rod bearings designed for Oldsmobile V8 engines (260, 307, 350, and 403 cubic inch displacements) from 1964-1990, with a .020 inch (.50mm) undersize crankshaft specification.

Key Features:

• Tri-metal construction with hardened steel backing, copper-lead intermediate layer, and electroplated lead-tin-copper overlay
• TM-77 bearing material capable of handling maximum loads up to 12,000 psi
• High eccentricity design compensates for rod bore distortion in high-RPM applications
• High crush factor ensures better bearing retention and seating
• Extra-thin overlay reduces friction and drag for increased horsepower
• .020 inch undersize for reground crankshafts
• Direct replacement for OE applications with upgrade potential from bi-metal bearings

Clevite P-Series bearings are ideal for engine rebuilds where more demanding use is anticipated, including motorsports, street performance, and heavy-duty applications. As the oldest members of the Clevite 77 performance bearing family, P-Series bearings are specifically intended for high-revving engines where RPM causes rod bores to narrow.
