Product Description
The Cummins 4932376 OEM Upper Connecting Rod Bearing (.020 / 0.50mm Oversize) is a precision-machined, genuine Cummins bearing designed for rebuilt and remanufactured 5.9L and 6.7L ISB engines requiring an oversize rod journal specification. This upper shell provides exact oil clearance, proper load distribution, and OE-level durability essential for long-term reliability in performance, towing, and daily-driven diesel applications.
When the crankshaft rod journals have been ground to a 0.020" (0.50mm) oversize specification, this bearing ensures the correct clearance is restored—something aftermarket bearings often fail to maintain under high heat and high pressure. Using genuine Cummins rod bearings is the only way to ensure factory-grade protection and longevity.
Fitment
- 2003–2007 Dodge Ram 2500/3500 with 5.9L ISB Cummins
- 2007.5–Present Dodge Ram 2500/3500 with 6.7L ISB Cummins
- Also used in ISB industrial and off-highway engines requiring 0.50mm oversize bearings
Note: This is the upper connecting rod bearing shell. Oversize bearings must match crankshaft journal machining; always verify via ESN and machine shop specs.

FAQ
What does .020 / 0.50mm oversize mean for this rod bearing?
It means the crankshaft rod journals have been machined 0.020" (0.50mm) undersize, requiring a matching oversize bearing to restore correct oil clearance.
Is this the upper bearing or lower bearing?
This part number (4932376) is the upper shell. The lower shell is Cummins part 4932377.
Do I need to replace all rod bearings when replacing one shell?
Yes. Rod bearings must always be replaced as a full matched set for proper load distribution and engine longevity.
Does this fit both 5.9L and 6.7L Cummins ISB engines?
Yes — as long as the engine requires 0.50mm oversize rod bearings. Fitment is ESN-dependent.
