Cummins ISX12 Parts
Not sure which part you need? Use our parts-request checklist.
Aftermarket and OEM-cross Cummins ISX12 parts, ready to ship same-day from Colorado. The ISX12 is the midrange-displacement workhorse below the bigger ISX15 — built for vocational, regional, and natural-gas duty cycles. We stock the wear and rebuild parts these engines actually go through: cylinder heads, fuel injectors, turbochargers, gaskets, and complete rebuild kits, with quality PAI Industries coverage as the backbone.
Got an OEM, superseded, or competitor part number? Send it over. We cross-reference it to the right ISX12 component and quote it fast. Free freight on orders over $1,000.
