Connecting Rod | Cummins ISX/QSX | 4059429

Connecting Rod | Cummins ISX/QSX | 4059429. Drilled style with new bushing included and pressed in.

Some early ISX engines have the articulated two piece pistons in them, as they originally came assembled from factory. These pistons need to be upgraded to the mono-therm style one piece steel pistons which also require a connecting rod upgrade.
