Cummins Parts
Cummins runs more highway miles than almost any other diesel on the road, and JAK'S Diesel stocks the parts to keep those engines turning. From the ISX15 and N14 to the M11, ISC/ISL and the legendary 6BT, we carry PAI Industries aftermarket components plus our own JAK'S Diesel Heads program — cylinder heads, fuel injectors, turbochargers, gaskets and full inframe rebuild kits.
