Engine & Performance Warehouse CB1643P4020 Connecting Rod Bearing Set Oversize - 0.020

The Engine & Performance Warehouse CB1643P4020 is a connecting rod bearing set manufactured to precise dimensional tolerances for reliable engine performance. Featuring a +0.020" (0.50mm) oversize specification, these bearings are designed for use during engine rebuilds where the crankshaft rod journals have been re-ground to restore proper surface finish and geometry.

Key Features:

• +0.020" Oversize: Engineered for re-ground crankshaft rod journals at the 0.020" undersize specification
• Precision Manufactured: Tight dimensional tolerances ensure proper oil clearance and long-term bearing life
• Quality Materials: Tri-metal or bi-metal construction provides excellent wear resistance and conformability
• OE-Style Design: Matches original equipment dimensions for straightforward installation during engine overhaul

These connecting rod bearings are an essential component of any professional engine rebuild, replacing worn or damaged original bearings to restore proper oil film thickness and reduce crankshaft wear. Always verify journal diameter with a micrometer before selecting oversize bearings.
