Best Injectors For 5 9 Cummins Common Rail for Dodge and QSB
A strong 5.9 Cummins common-rail injector choice matches the engine’s exact part number and model-year range, and suits owners replacing one injector or a full set. For Dodge Ram owners, IMELBUFF’s six-injector set lists the 0445120238, 0986435505, and 5263316 numbers and specifies the 325-hp 5.9L ISB from 2004.5 to Other options cover broader pickup-year ranges, a stated 2003–2004 application, or QSB industrial engines used in equipment.
Those distinctions matter: several products use similar-looking injectors but list different part numbers and applications. This comparison puts pickup-specific matches first, then separates single-injector listings from six-piece sets and industrial-engine options.
Verify the number on your existing injector and the engine details before ordering.
IMELBUFF 5.9L ISB Six-Pack leads for owners of a 2004.5–2007 Dodge Ram 2500, 3500, 4500, or 5500 with the 325-hp 5.9L ISB. It is explicitly listed as a six-injector set and names the 0445120238, 0986435505, and 5263316 part numbers. That combination makes its stated pickup application more direct than the QSB-oriented listings.
Check your original injector number and engine configuration first; the year range and horsepower specification are part of this product’s stated fit, not a universal fit claim for every 5.9 Cummins.

Detailed Reviews: Best Injectors For 5 9 Cummins Common Rail
#1 · Best Overall
1. IMELBUFF 5.9L ISB Six-Pack
- Material: High Speed Steel
- Material Type: High Speed Steel
Best for: 325HP ISB six-injector set.
Why it ranks #1: Its six-injector set lists 0445120238, 0986435505, and 5263316 for the 325-hp 5.9L ISB in 2004.5–2007 Dodge pickups.
A specific 325HP Cummins ISB 5.9L application from 2004.5-2007 gives this IMELBUFF six-pack a sharply defined pickup fit. It names Dodge Ram 2500, 3500, 4500 and 5500 models, helping owners compare both engine output and truck series before planning replacement.
The six included injectors support a complete set replacement for the stated 325HP ISB engine, and the 2004.5-2007 range helps distinguish this application from other 5.9L Ram configurations. Listed numbers 0445120238, 0986435505 and 5263316 provide additional cross-checks during parts identification. The listing also specifies high-speed steel and offers customer support, but its fit details are narrower than a general 5.9L description.
- Includes six fuel injectors.
- Specifies Cummins ISB 5.9L at 325HP.
- Lists 2004.5-2007 Dodge Ram 2500, 3500, 4500 and 5500 pickups.
- Provides part numbers 0445120238, 0986435505 and 5263316.
- The stated application is restricted to 2004.5-2007 325HP ISB configurations.
Skip it if you own a 2008-2009 5.9L pickup; NEXDYNAMI's description extends its listed applications through those years.
Choose this set when your Ram matches the listed 325HP ISB 5.9L engine, 2004.5-2007 years and named truck series. That specific output and year boundary matters; verify the injector numbers against your application before installation.

2. NEXDYNAMI 5.9L Injector Set
Best for: Late-model 5.9L pickup set.
Why it ranks #2: This six-piece listing gives part numbers 0986435505, 5263316, and 0445120238 and covers late-production 2004 through 2009 5.9L pickups.
Six injectors with connector are listed for Dodge/Cummins 5.9L diesel pickups, giving owners a complete quantity for a multi-injector service job. The description names 0986435505, 5263316 and 0445120238, while its year details reach from late-production 2004.5 trucks through 2009 applications.
The six-piece quantity makes this listing relevant when replacing more than one injector, and the stated connector inclusion is a practical detail for identifying the offered configuration. Corrosion-resistant materials are claimed for long-lasting performance, while the description names several part numbers to compare with the installed unit. Check the year wording carefully: the title says 2004.5-07, whereas the expanded compatibility description also lists 2008-2009 pickups.
- Includes six diesel injectors with connector.
- Lists Dodge/Cummins 5.9L pickup applications.
- Names part numbers 0986435505, 5263316 and 0445120238.
- Claims corrosion-resistant materials and easy installation.
- The title ends its year range at 2007, while the description extends it through 2009.
Skip it if you want an unambiguous 2004.5-2007 fit range; IMELBUFF lists that exact span for its 325HP ISB 5.9L six-pack.
Consider this six-piece NEXDYNAMI set if your 5.9L pickup and connector configuration match its details. The title and description differ on the final model year, so resolve that discrepancy against the vehicle and injector numbers before choosing it.

3. Generic 5.9L Injector
Best for: 2004-2009 Ram replacement.
Why it ranks #3: It specifies a common-rail injector for 2004–2009 Dodge Ram 2500 and 3500 trucks, with part numbers 5263316NX, 0986435505, and 0445120238.
A 2004-2009 application range for Cummins Dodge 5.9L Ram 2500 and 3500 pickups makes this injector relevant to owners checking those specific trucks. Its listed numbers—5263316NX, 0986435505, 0445120238 and 5263316—provide concrete references for comparing the required replacement part.
The stated Ram 2500 and 3500 fit range gives a clear vehicle and year window, while the four listed part numbers help owners compare the installed injector or service information. This is a single common-rail injector listing rather than a stated six-piece set, so buyers planning a complete bank replacement should account for that distinction. The product information also calls for matching the engine model or required part number before installation.
- Lists Cummins Dodge 5.9L Ram 2500 and 3500 pickups.
- States a 2004-2009 application range.
- Provides four injector part-number references.
- Identifies the product as a common-rail injector.
- The listing identifies an injector but does not state a multi-injector set quantity.
Skip it if you need a stated six-injector set; Arko Tractor Parts specifies six pieces for 2003-2004 Ram 2500 and 3500 trucks.
This listing fits buyers seeking a common-rail injector for the stated 2004-2009 Ram 2500 or 3500 5.9L application. It does not specify a set quantity, so it is less clear for shoppers planning a full six-injector replacement.

4. Arko 5.9L Injector Set
Best for: Matched-flow early Ram set.
Why it ranks #4: The listing specifies a six-piece set for 2003–2004 Dodge Ram 2500 and 3500 trucks with a 5.9L Cummins, but its title also says 12V.
Matched flow rates across six injectors are the defining feature of this Arko Tractor Parts set, intended to support consistent fueling across cylinders. Its stated application is specific: 2003-2004 Dodge Ram 2500 and 3500 trucks with the 5.9L Cummins diesel, giving owners a clear year and vehicle reference.
The six-piece set is tested for matched flow performance, which the listing connects with smooth idle quality and throttle response. Integrated seals and O-rings are included, supporting a system refresh without separately sourcing those stated components. The direct drop-in description is tied to 2003-2004 Ram 2500 and 3500 5.9L trucks, so this is a focused option rather than a broadly listed fit across later common-rail model years.
- Six-piece common-rail injector set.
- Matched flow performance is stated across the injectors.
- Integrated seals and O-rings are included.
- Specifies 2003-2004 Dodge Ram 2500 and 3500 5.9L applications.
- The stated truck application is limited to 2003-2004 Ram 2500 and 3500 models.
Skip it if you have a 2004.5-2007 325HP ISB pickup; IMELBUFF lists that later year and engine combination.
This set suits owners of the specifically listed 2003-2004 Ram 2500 or 3500 5.9L truck seeking matched-flow injectors with integrated seals and O-rings. Its narrow year range is the key boundary for choosing it.

5. HIRINTOL QSB Injector
- Material: Metal
- Material Type: Metal
Best for: QSB and Komatsu cross-check.
Why it ranks #5: It lists 0445120059 and 0445120231 for QSB5.9, QSB6.7, and QSB4.5 engines, with numerous Komatsu equipment applications rather than a Dodge pickup fit.
A broad Komatsu machine list is the clearest differentiator of this HIRINTOL injector, helping equipment owners compare their machine against named PC, PW, WA and GD models. It lists Cummins QSB4.5, QSB5.9 and QSB6.7 compatibility and several replacement numbers, useful details when identifying a matching service part.
The listed QSB engine family gives buyers an engine-level compatibility reference, while the part-number list includes 0445120059, 0445120231, 4945969 and 5263262 for cross-checking an existing injector. Its Komatsu references extend beyond excavators to PW, WA and GD models, which can help fleet maintainers identify relevant equipment applications. Because the listing cautions that similar injectors can differ in part number and flow rate, verify the exact number before ordering.
- Lists Cummins QSB4.5, QSB5.9 and QSB6.7 engines.
- Names a range of Komatsu PC, PW, WA and GD models.
- Provides multiple replacement part numbers for cross-checking.
- Specifies metal as the material.
- Its stated engine coverage is QSB-series; it does not specify a Dodge pickup year range.
Skip it if you need an explicitly year-ranged Dodge Ram pickup application; Arko Tractor Parts lists 2003-2004 Ram 2500 and 3500 trucks.
This is a candidate for equipment maintainers whose Cummins QSB engine and Komatsu model match the supplied references. Its listed engine coverage is QSB-focused, so buyers shopping for a specific Dodge pickup application should use a listing with that vehicle detail.

6. IMELBUFF QSB Injector Set
- Material: High Speed Steel
- Material Type: High Speed Steel
Best for: QSB equipment fleet refresh.
Why it ranks #6: This six-injector set names QSB5.9 among its engine applications, but is primarily specified for Komatsu and Hyundai equipment rather than Dodge pickups.
A six-injector set paired with QSB5.9 and QSB6.7 engine coverage makes this IMELBUFF option relevant for a full injector refresh on compatible equipment. Its application list also names Komatsu PC200-8, PC220-8, PC230-8 and PC270-8 excavators, giving equipment owners concrete vehicle references to check against their setup.
The included six injectors support replacing a complete set rather than sourcing individual units, while the listed QSB4.5, QSB5.9, QSB6.7 and ISB6.7 engines help narrow the engine match. Komatsu SAA6D107E-1 and several PC-series excavators add useful equipment references for buyers checking an existing part number. The listing also names Hyundai HL770-7A, but its wide engine and machine coverage makes careful part-number matching important before installation.
- Six fuel injectors are included for a set replacement.
- Lists Cummins QSB5.9 and QSB6.7 compatibility.
- Names Komatsu PC200-8, PC220-8, PC230-8 and PC270-8 excavators.
- Lists high-speed steel as the injector material.
- The stated vehicle coverage centers on equipment applications rather than Dodge pickup year ranges.
Skip it if you need a listing centered on Dodge Ram pickup years; NEXDYNAMI identifies 2004.5-2009 5.9L pickup applications.
For equipment owners refreshing a compatible QSB-powered machine, this six-piece set offers useful engine and excavator references. Treat the listed applications as a starting point and match the injector numbers to the engine before installation.

View on AmazonAvoid the similar-number compatibility trap
A similar-looking injector is not enough to establish fit; match the complete part number and engine application before ordering. These listings illustrate why: pickup-focused products name 0445120238, 0986435505, or 5263316, while the QSB listings center on 0445120059 and The latter also list QSB4.5, QSB5.9, and QSB6.7 engines and equipment such as Komatsu excavators and wheel loaders.
The number 5.9 appears in both truck and industrial applications, but that alone does not make the injectors interchangeable. Even a broad pickup-year range, such as the NEXDYNAMI listing’s late-production 2004 through 2009 coverage, should not replace checking the number on the installed injector.
Confirm the engine configuration and the full number with the seller when uncertain. The Arko title’s 12V wording alongside a 2003–2004 common-rail truck application is another reason to resolve ambiguous listing details before buying.
Choose a set size to match the repair
These products do not all supply the same number of injectors, so confirm the package contents against the scope of your repair. IMELBUFF 5.9L ISB Six-Pack, NEXDYNAMI 5.9L Injector Set, and IMELBUFF QSB Injector Set explicitly list six injectors. Arko describes a complete six-piece set, while the generic 5.9L listing describes a common-rail injector without stating a six-piece quantity.
The HIRINTOL description likewise identifies a fuel injector but does not state a set count in the supplied details. A set can suit a full-system replacement, but buying multiple units is not automatically necessary when diagnosing a single-cylinder fault.
Conversely, a single-injector listing may not be enough when the repair plan calls for all six. Confirm quantity, seals or other included pieces, and the exact part number before checkout; the supplied data does not establish that every listing includes installation hardware.
How to Choose 5.9 Cummins Injectors
Part number and engine application
Start by matching the complete injector number and engine application, rather than relying on the 5.9L label alone. The pickup listings identify 0445120238, 0986435505, and 5263316, while the QSB-focused options list 0445120059 and IMELBUFF QSB Injector Set and HIRINTOL QSB Injector both include QSB5.9 among several engine families, but their applications emphasize equipment.
The pickup-specific IMELBUFF 5.9L ISB Six-Pack states 325-hp ISB fitment for 2004.5–Choose a truck listing when those details match your vehicle; consider a QSB product only when your engine and injector number match its industrial application.
If uncertain, compare the number on the existing injector with the listing and ask the seller to verify.
Model-year and vehicle fit
Check the listed year range and vehicle application against your exact truck before choosing. IMELBUFF 5.9L ISB Six-Pack specifies Dodge Ram 2500, 3500, 4500, and 5500 pickups from 2004.5–NEXDYNAMI 5.9L Injector Set describes late-production 2004 through 2009 5.9L pickups, and Generic 5.9L Injector lists Dodge Ram 2500 and 3500 from 2004–2009.
Arko 5.9L Injector Set specifies 2003–2004 Ram 2500 and 3500, though its title also describes the engine as 12V. Buyers with a clearly matching 2004.5–2007 325-hp truck have the most tightly stated application in the IMELBUFF pickup set; those outside that range should verify the part number and engine details rather than extending fitment by assumption.
One injector or a six-piece set
Choose package quantity to match whether the repair calls for one injector or a full set. IMELBUFF 5.9L ISB Six-Pack and NEXDYNAMI 5.9L Injector Set explicitly provide six injectors, as do the IMELBUFF QSB set and Arko’s described six-piece kit. By contrast, Generic 5.9L Injector is presented as a common-rail injector, and the supplied HIRINTOL details do not specify a quantity.
A six-piece package is the relevant format when replacing all cylinders, while a single-injector listing may suit a targeted replacement if that is what diagnosis calls for. Do not infer seals, o-rings, or other included hardware from the product title: Arko mentions integrated seals and o-rings, but the other supplied listings do not consistently confirm them.
Which 5.9 Cummins Injector Should You Choose?
For a 2004.5–2007 Dodge Ram with the 325-hp 5.9L ISB, choose IMELBUFF 5.9L ISB Six-Pack: it names the truck range, engine output, three matching part numbers, and six injectors. If your pickup is a late-production 2004 through 2009 and its existing injector matches the listed numbers, NEXDYNAMI 5.9L Injector Set is another six-piece option with a broad stated range. For a repair that calls for one injector, consider Generic 5.9L Injector, but verify its package quantity and exact part number.
Arko 5.9L Injector Set states a 2003–2004 application, yet its 12V wording warrants clarification. The QSB-oriented HIRINTOL QSB Injector and IMELBUFF QSB Injector Set are for matching industrial engine applications, not general Dodge pickup replacements.
Frequently Asked Questions
How can I confirm whether my 5.9 Cummins needs injector part number 0445120238 or 0445120231?
Check the number on your original injector and confirm your engine configuration and vehicle application before ordering. The listed products associate 0445120238 with a 2004.5–2007 325-hp ISB pickup set, while some QSB-oriented listings name Do not treat either number as a universal fit; verify the match for your engine.
Can I replace only one common-rail injector, or should I replace all six?
Either approach depends on the repair diagnosis and the exact replacement product. The roundup includes a single-injector listing as well as products explicitly sold as six-injector sets. If replacing one, verify its part number and package quantity; if considering a set, confirm that all six match your engine and application.
What should I check after installing replacement common-rail injectors?
Confirm that the installed injectors match the original part number and the engine application, then check for fuel leaks and warning lights before normal use. Follow the vehicle or engine service procedure for installation and any required setup. If operation seems abnormal, stop and have the installation and injector fit verified.
Are QSB-listed injectors suitable for a Dodge Ram 5.9 Cummins?
Not automatically. The QSB-oriented products identify QSB engine applications, and the editorial verdict distinguishes them from the pickup-focused options. For a Dodge Ram, compare the original injector number, engine configuration, and stated vehicle fitment.
Choose a QSB listing only when your engine is a matching QSB application.
How can I tell whether a listing is for one injector or a complete set?
Read the title and package details before ordering. Some titles explicitly say “6-Pack” or “6,” while the 2004–2009 pickup listing is presented as a single common-rail injector. The 12V set title does not state its quantity, so confirm the package contents and exact part number with the seller.
Final Words
For a 2004.5–2007 Dodge Ram with the 325-hp 5.9L ISB, the IMELBUFF ISB six-pack is the clearest match in these listings because it states the truck range, engine output, six-injector quantity, and relevant part numbers. Other applications call for closer verification: compare your original injector number and engine configuration, and confirm quantity before ordering. Treat QSB listings as industrial-engine options, not general pickup replacements.
