King Engine Bearings CR Connecting Rod Bearing Set Chevy SBC Gen III/IV

The King Engine Bearings CR Series connecting rod bearing set (also called rod bearings or main rod bearing inserts) is built to give an engine rebuild a reliable, precise-fitting foundation. King Engine Bearings is a specialist bearing manufacturer. The CR line covers OE-replacement sets for stock and street rebuilds, along with race-focused sets for higher-load use.

Key Features:

• Precision manufacturing: Made to tight tolerances for consistent oil clearance and a proper fit on the connecting rod and crankshaft journal.
• Multiple bearing technologies: The CR line includes OE-replacement bi-metal, polymer-coated, and race-oriented designs, so builders can match the bearing to the application.
• Durability: Engineered for wear resistance and load capacity under continuous operation, from daily-driver rebuilds to circle track and drag racing.
• Multiple sizes: Available in standard and undersize options to suit crankshafts that have been machined during a rebuild.
• Engine-specific design: Each CR part number is engineered for a specific engine family's journal and housing dimensions.
