FAQ
What does .010 undersize mean?
A .010 undersize bearing is designed for crankshaft rod journals that have been machined .010 inch smaller than factory specifications. This restores proper bearing clearances after crankshaft repair or machining.
Will this fit both 5.9L and 6.7L Cummins engines?
Yes. The Cummins 4932375 upper rod bearing is commonly used in 2003–2018 ISB 5.9L and 6.7L Cummins diesel engines equipped with cracked-cap connecting rods.
Is this an OEM Cummins part?
Yes. The 4932375 is a genuine Cummins connecting rod bearing manufactured to Cummins OEM specifications for fit, durability, and performance.
Can I use this on a standard crankshaft journal?
No. This bearing is specifically designed for crankshafts that have been machined .010 inch undersize. Standard journal crankshafts require standard-size bearings.
Should I replace both upper and lower rod bearings during a rebuild?
Yes. Most engine rebuilds replace both upper and lower connecting rod bearing shells as a matched set to ensure proper wear patterns and bearing clearances.
Why use genuine Cummins bearings?
Genuine Cummins bearings provide OEM metallurgy, precision machining, and proven durability that help maintain proper oil pressure, reduce wear, and maximize engine longevity.
