Product Description
Cummins 4932376 OEM Upper Connecting Rod Bearing (.020 / 0.50MM) – Ram 5.9L/6.7L
The Cummins 4932376 OEM Upper Connecting Rod Bearing (.020 / 0.50mm Oversize) is a genuine Cummins replacement bearing engineered for rebuilt and remanufactured 5.9L and 6.7L ISB diesel engines requiring a .020 inch (0.50mm) oversize rod bearing. Manufactured to Cummins OE specifications, this upper rod bearing provides proper oil clearance, load distribution, and long-term durability for high-mileage, towing, performance, and daily-driven diesel applications.
When crankshaft rod journals have been machined .020 inch (0.50mm) undersize during engine rebuilding, the correct oversize bearing must be installed to restore factory oil clearances. The Cummins 4932376 upper rod bearing is designed specifically for these applications, helping ensure reliable lubrication, reduced friction, and extended engine life.
