Upgrade your 2003-2004 Dodge Ram 5.9L Cummins with the Dynomite Diesel (DDP) 305-120 remanufactured injector set. These 45% over-stock injectors deliver approximately +120 horsepower and provide the extra fuel needed for high-output builds, supporting up to 775–900 RWHP when paired with proper supporting modifications.

Each injector is remanufactured using brand-new OE components, then precision-balanced and flow-matched as a complete set of six for consistent fueling, smoother idle, and reliable performance. SAC-style nozzles improve atomization for cleaner combustion, better drivability, and reduced smoke compared to many aftermarket options.

Fitment: 2003–2004 Dodge Ram 2500/3500 with 5.9L common-rail Cummins.

Requirements: A modified or dual CP3 pump is mandatory. Custom tuning and supporting airflow upgrades (turbo, exhaust, etc.) are strongly recommended to safely utilize the extra fuel.

Key details:

• Remanufactured condition with new internals
• 45% over stock / 120HP rating
• Balanced and matched set
• SAC nozzle design
• Core charge applies

These injectors are a proven choice for street/tow or performance-oriented 5.9 Cummins trucks that need more fuel without jumping to extreme nozzle sizes. Pair them with the right pump, tuner, and supporting parts for a noticeable power increase and dependable operation.
