1. Application & Compatibility

Primary Engine:

2003–2007 Cummins ISB 5.9L (6BT) – Used in Dodge Ram 2500/3500 (third-gen) and some industrial/marine applications.

Fits both standard output (325–600 HP range) and high-output (HO) variants.

May also cross-reference to:

Some early ISB 6.7L applications (but confirm compatibility).

Industrial/agricultural 5.9L engines (e.g., generators, pumps).

2. Injector Type & Specifications

Technology: High-Pressure Common Rail (HPCR) injector (Bosch-based design).

Pressure Range: Operates at 23,000+ PSI (exact specs vary by calibration).

Nozzle Type: Likely a sac-type nozzle (for precise fuel atomization).

Electrical Connector: Uses a Euro-style (Bosch) solenoid connector.

3. Key Features

Emissions Compliance: Designed for EPA 2004–2007 emissions standards (pre-DPF era).

Performance Role: Critical for fuel efficiency, power output, and emissions control.

Upgrades: Some aftermarket versions (e.g., remanufactured or performance-tuned) are available.

4. Common Failures & Symptoms

Typical Issues:

Clogging from dirty fuel (lack of filtration).

Solenoid failure (electrical issues).

Internal wear (leaking/spray pattern degradation).

Symptoms of Failure:

Hard starts, rough idle, or misfires.

Excessive black/white smoke.

Loss of power or poor fuel economy.

Fault codes like P0251 (injector circuit malfunction) or P020X (cylinder-specific injector errors).

What kind of CUMMINS fuel injector will you get from Trade Ultra ?

1. You’ll get it all with; 100% O-ring replacement for proper sealing, a new Actuator Assembly, Spill Valve, To top it off, every nozzle is tested for 100% proper fuel delivery. It just doesn’t get much better than that.

2. Meticulous testing? You got it! This injector goes through a strict reassembling and testing process for fuel delivery, injection pressure, and timing. If you want more power and reduced emissions, this is the way to go.

3.To put things in perspective, you’re getting proper fit and function because strict OE specifications are met.

There’s no doubt you’ll get exceptional quality and consistency. Why? Each injector is completely disassembled, components are cleaned, and lastly this bad boy is checked for wear and breakage. It comes from the reconstruction of China’s top fuel system OEM manufacturing factory, you can’t beat it .
