Made from Clevites famous tri-metal design, these bearings are great for stock to performance applications. Incorporates the strength of a copper-lead alloy layer on a precision steel back with electroplated babbit surface with a 1/2 groove on upper shell.

These bearings do not have enlarged chamfers required by most aftermarket forged steel crankshafts. We also carry these in the "H" series bearings, if you require a chamfered bearing. See our ebay store for other Chevy Bearings, and more!
