Clevite Connecting Rod Bearing part number: CB1442P (Standard)The steel backing on the Clevite Tri-Metal 77 Connecting Rod Bearings provides strength and durability. The Bi-Metal Babbitt overlay provides the conformability and Load Capacity. The Third layer - Micro-Babbitt overlay provides the critical surface Embedability Conformability and has far more forgiveness than bi-metal. This ideal design has properties not found in many original equipment bearings. In most cases Clevite Tri-Metal 77 Bearings are an upgrade over a stock bearing, or three times better.It takes Three Layers to be Number One, and Clevite 77 Tri-Metal Bearings are it ! Engineering quality engine bearings involves a number of interdependent factors. Here is how Clevite 77s Tri-Metal cast copper lead material compares to bi-metal bearings on the most important of these factors:Seizure Resistance: Tri-Metal bearings have significantly greater seizure resistance than bi-metal
