Our extensive inventory guarantees you'll find the right components to keep your Cummins engines operating smoothly and efficiently. Here's a detailed look at the applications for which we supply top-quality aftermarket engine parts:

  
  

• • On-Highway & Commercial Vehicles

    • Engines for trucks, buses, coaches, RVs, and vocational vehicles.

    • Light & Medium Duty

      • Power delivery trucks, buses, utility vehicles, and light commercial applications.
      • B-Series: 3.9 L to 6.7 L inline-4/6 engines for medium-duty trucks, buses, and vocational vehicles.
      • ISB / QSB: Electronic/fuel-injected and off-highway versions of B-Series for vocational trucks, buses, and some construction equipment.

    • Heavy Duty Truck Engines

      • High-power engines for long-haul and severe-service applications.
      • X-Series (e.g., X12, X13, X15): Modern heavy-duty inline-6 diesels for highway tractors and heavy trucks (≈350–605+ hp).
      • Legacy ISX: Earlier heavy truck engine model, predecessor to the X-Series for over-the-road applications.

  • Off-Highway, Construction & Industrial Vehicles

    • Engines for heavy equipment such as excavators, loaders, agricultural machines, and mining rigs.

    • Mid-Range Industrial

      • QSB Series: Off-highway variants of B-Series engines for construction machines and agricultural equipment.
      • ISM / QSM Series: 11–15 L engines for heavier industrial equipment, large loaders, concrete mixers, and construction machinery.

    • Large Industrial

      • N Series (e.g., NT855/NTA855): 8–14 L engines for continuous heavy-duty use in construction, mining, and oilfield equipment.
      • KTA & QSK Series: Larger V-engines (19 L and above up to ~60 L+) for demanding industrial applications, including mining dump trucks and heavy haul equipment.

  • Marine & Offshore

    • Engines for propulsion, auxiliary power, and heavy maritime use.
    • N Series Marine Variants: Reliable workhorse engines (e.g., N14, N855) for fishing boats, towboats, and auxiliary propulsion.
    • QSK Marine Series: High-performance marine diesels (e.g., QSK19, QSK38, QSK60) meeting emissions standards for large commercial vessels and offshore craft.
    • Marine Genset Variants: Generator versions of industrial cores (e.g., QSX15-G, KTA19-G) providing shipboard electrical power.

  • Power Generation (Genset)

    • Stationary and mobile power plants for backup or prime power.
    • Engines used in generator sets from small commercial power to large industrial and data center backup units (7.5 kVA up to ~3750 kVA).

    • Typically use industrial and marine-derived blocks:

      • B Series: Small gensets
      • QSB / QSC: Mid-range power
      • QSK / KTA: High-power generation solutions

  • Gas & Alternative Fuel Variants

    • Natural gas and dual-fuel versions of some diesel engines, especially in heavy-duty and bus applications.
    • X12N / ISL-G: Natural gas engines for urban buses and vocational fleets offering cleaner emissions, suitable for fleets with natural gas fueling infrastructure.
