Engine & Performance Warehouse CB1670P6010 Connecting Rod Bearing Set 0.010 Undersize

The Engine & Performance Warehouse CB1670P6010 is a 6-piece connecting rod bearing set ground to 0.010-inch undersize, designed for use during engine rebuilds where crankshaft rod journals have been reground to the first undersize specification. These precision-manufactured rod bearings provide a reliable, properly fitted interface between the connecting rod and the crankshaft journal to restore proper oil clearance and engine performance.

Key Features:

• 6-piece connecting rod bearing set — one upper and one lower half per journal
• 0.010-inch (0.25mm) undersize to match reground crankshaft rod journals
• Precision-bored inside diameters for consistent oil clearance and surface finish
• Bimetal construction with aluminum-alloy bearing surface for excellent wear resistance and seizure resistance
• Lead-free aluminum-silicon alloy formulation for compatibility with modern engine oils
• Split-shell design for straightforward installation — one half seats in the connecting rod, the other in the rod cap
• Manufactured to strict dimensional tolerances for reliable, long-lasting performance

These rod bearings are an essential component in any engine rebuild or crankshaft regrind job. Proper bearing selection — matching the undersize to the actual ground journal diameter — is critical for achieving correct oil clearance and maximizing engine longevity. Always verify crankshaft journal measurements with a micrometer before selecting bearing size.
