Engine & Performance Warehouse CB1670P6020 Connecting Rod Bearing Set 6-Piece 0.020" Undersize

The Engine & Performance Warehouse CB1670P6020 is a six-piece connecting rod bearing set sized at 0.020" (0.50mm) undersize, designed for engine rebuilds requiring a ground or undersized crankshaft journal. This set cross-references to the industry-standard CB-1670P rod bearing specification and is packaged by EPWI for professional engine rebuilders.

Connecting rod bearings seat at the junction of the connecting rod and the crankshaft journal, providing a precision friction surface that allows smooth piston articulation throughout the full stroke cycle. Proper bearing clearance is critical for maintaining oil film integrity, preventing journal wear, and ensuring long engine life after a rebuild.

Key Features:

• Six-piece set — enough for a complete 6-cylinder engine rebuild
• 0.020" (0.50mm) undersize — designed for use with reground crankshaft journals
• Precision-bored inside diameters for consistent clearance and optimal oil film
• Bi-metal or tri-metal construction (per CB-1670P specification) for durability and conformability
• Meets or exceeds OEM specifications for journal surface interaction
• Direct replacement for engines requiring the CB-1670 rod bearing specification

This bearing set is intended for professional engine builders and machine shops performing a full engine overhaul. When replacing connecting rod bearings, it is recommended to have the crankshaft inspected, polished, or reground as needed to ensure proper clearance and a long-lasting repair. Always verify journal size with a micrometer before selecting bearing undersize.
