Overview

The Clevite P-Series Rod Bearings CB-663P-30 are direct replacement engine bearings designed for high-revving engines. They feature a tri-metal TM-77 construction and are intended to compensate for rod bore narrowing at high RPM. These bearings have higher eccentricity and a high crush factor for secure retention.

Part #: CB663P30

Ideal for rebuilding engines where more demanding use is anticipated, such as heavy duty, motorsports, or street performance. As it is the most versatile replacement, Clevite engine bearing P-Series is suitable for most OE applications. Due to the increased load capacity of the Tri-Metal design, it is a suitable upgrade from Bi-Metal engine bearings.
