CUMMINS Connecting Rods

Cummins diesels come back into service year after year in trucks, generator sets, excavators, mining haul trucks and marine installations, and the connecting rod is a part most workshops order by number. This category brings together our Cummins rods across the small and large ends of the range.

On the light side we list the ISF2.8 and ISB 3.8 rods, the A2300 rod used in forklifts and mini excavators, and the four- and six-cylinder B series rods for 4BT, 6BT and 5.9L engines. Mid-range coverage includes 6CT, 6L ISC/ISL, L10, M11 and the 6LTAA and L89L family, while the heavy end covers NT855, K19, KTA19, QSK19, KT38, KTA38, QSK45, QSK60, ISX15, ISG12, QSG12, ISZ13 and QSZ13. Numbers in this group include 3698310 with 3697259 for the ISG12 and QSG12, 2882582NX with 3689108 and 3679797 for the ISX15, 3632225 with 3628824 and 3626494 for KT38 and KTA38, 3418500 with 218808 for the NT855, 3811995 with 3043911, 3007573 and 3014453 for K19, KTA19 and QSK19, and 3643083, 3644676 and 3640518 for the QSK45 and QSK60.

Rods are forged from alloy steel and precision machined, with dimensional checks run batch by batch. Stock models ship without a minimum order quantity, so trial and sample lots are welcome. If your engine serial number or the number on the old rod is not clear, send it over and we will confirm the right part first.
