Product Description
CUMMINS 5257364 OEM ENGINE CONNECTING ROD – ISB 6.7L (2007.5–2018)
The genuine CUMMINS 5257364 OEM engine connecting rod is the factory-engineered rod used in the 6.7L ISB Cummins platform from 2007.5–2018. This forged-steel connecting rod maintains the precise mass balance, alignment, and oiling control required for proper piston operation in heavy-duty diesel engines. If you are rebuilding a 6.7L Cummins short block, correcting a thrown rod, or replacing worn rotating assembly components, nothing fits or performs like real Cummins hardware.
Each connecting rod is manufactured to Cummins’ strict tolerances for big-end sizing, center-to-center length, small-end fitment, and fracture-split cap alignment. These tight specifications are critical for maintaining oil film thickness, bearing life, piston stability, and long-term engine durability — especially in towing, commercial, or high-load environments.

Frequently Asked Questions
WILL THIS CONNECTING ROD FIT MY 6.7L CUMMINS?
Yes—CUMMINS 5257364 fits most 2007.5–2018 6.7L ISB engines. Because of ESN-specific variations, always confirm with your engine serial number before ordering.
IS THIS A COMPLETE ROD ASSEMBLY?
This listing is for the connecting rod only. Bearings, wrist pins, and pistons are sold separately.
DO CONNECTING RODS NEED TO BE WEIGHT-MATCHED?
Yes. Cummins rods are manufactured to tight mass tolerances. When replacing a single rod, verify balance within OEM limits.
CAN THIS ROD BE USED IN PERFORMANCE BUILDS?
Yes—OEM Cummins rods are strong, but high-horsepower builds may require forged aftermarket alternatives. For stock or towing applications, OEM rods are ideal.
IS THIS A GENUINE CUMMINS PART?
Yes—CPP Diesel supplies only authentic Cummins-manufactured components for maximum durability and reliability.
