Clevite Connecting Rod Bearing part number: CB663A  (Standard)

Clevite AL-5 Bi-Metal Bearings:

As more and more OE manufacturers shift to aluminum bearings in OE engines, Clevite has introduced a new line of engine bearings designed to be the highest quality replacement bearings in the industry. Clevite AL-5 Bi-Metal Connecting Rod Bearings carry on the tradition and reputation that Clevite has built throughout the course of time.

Clevite AL-5 Bi-Metal Connecting Rod Bearings feature a 100% lead free aluminum silicon Bi-Metal material; this includes 60% more silicon than leading competitor's Bi-Metal material for better conditioning of journal surfaces.

Clevite AL-5 Bi-Metal Connecting Rod Bearings also offer greater wear resistance than leading competitor's bi-metal material, as well as greater seizure resistance. Clevite AL-5 Bi-Metal Engine Bearings feature 100% bored ID's for precision and surface characteristics and where appropriate - straight shell main bearings utilizing an "umbrella" groove that allows for superior oil control and improved pressure.


When installing any bearing
DO NOT ATTEMPT TO POLISH THE BEARING RUNNING SURFACE WITH ANY TYPE OF ABRASIVE PAD OR PAPER.
Bearing overlay layers are extremely soft and thin, typically .0005” on high performance parts.
These thin layers can easily be damaged or removed by abrasive media. Because the overlay layer is electroplated,
it may exhibit microscopic plating nodules that make it feel slightly rough.
The nodules are the same material as the rest of the plated layer and will quickly be flattened by the shaft.
