Cummins original Common Rail Fuel Injector 4954801 4326784 4954374 Replacement for OEM 4326781 for QSX60 QSK60 QSK45 Sprayer Excavator Truck Construction Machinery Parts original new injector

For maintenance teams managing Cummins high-horsepower engines, clear part identification is essential. This diesel fuel injector assembly is listed under OE number 4954374 for the QSK60 product series, with QSK60 and QSK95 heavy-duty engine applications included in the product references. Its functional role is within the diesel fuel-injection system, where the injector assembly forms part of the engine’s fuel-delivery equipment. Selection should therefore be based on the engine reference and verified part number, not on the equipment category alone.

The cross-reference set includes 4326784, 4326784NX, 4326784PX, 4326784RX, 4954374NX, 4954374PX, and 4954374RX. Presenting these identifiers together helps procurement teams, distributors, and workshops compare service documentation, review supersession or suffix references, and reduce ambiguity during replacement sourcing. The listing is presented as an OE-reference replacement; no additional condition, certification, packaging, or quality-standard details are assumed. Buyers should confirm the required number, suffix, and engine configuration before placing an order.

Referenced equipment uses include mining trucks and heavy equipment, marine propulsion, generator and power units, and oilfield or oil and gas equipment. These references make the listing suitable for industrial parts catalogs serving several heavy-duty sectors while keeping the QSK engine application central. Its principal B2B advantage is consolidated identification: one OE number, seven cross numbers, and clearly stated application references support efficient quotation, inventory review, and fitment checking.
