Cummins Parts

Not sure which part you need? Use our parts-request checklist.

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.

Not sure which family you need? Pick your engine platform below, or send us an OEM or competitor part number and we'll cross-reference it. We ship same-day from Colorado with free freight over $1,000.

Shop Cummins by engine: ISX / ISX15 / X15, ISX12, N14, ISM / M11, ISC / ISL, B-Series (ISB / 6BT / 4BT / QSB), 855 / L10 Big Cam, 6C 8.3, QSX / QSM · X15 single-cam rebuild kits, ISX dual-cam rebuild kits.
