S&S Diesel 325-80SAC-SET 80% Over New Injector Set – 2004.5-2007 5.9L Cummins

Upgrade your late 5.9L Cummins with a true performance injector set from S&S Diesel Motorsport. The 325-80SAC-SET delivers approximately 80% more nozzle flow than stock while maintaining the clean atomization, consistent cylinder-to-cylinder balance, and durability that S&S is known for.

These are brand-new injectors (not remanufactured) built with SAC nozzles that undergo a proprietary honing process for clean, uniform orifice geometry. Each set is precision flow-matched — nozzles to roughly 1% variance and complete injectors to approximately 3% — and validated across multiple pressure and energizing points to OE-style standards. Injection rate shape is aligned for better drivability and control compared to many high-flow alternatives.

Key Features

• ~80% increased nozzle flow over stock
• Brand-new injector bodies with SAC nozzles
• Proprietary nozzle honing for consistent hole quality and atomization
• Tight set-matching for balanced fueling across all six cylinders
• Improved injection rate shape
• Direct-fit for late 5.9 common-rail applications

Fitment

2004.5–2007 Dodge Ram 2500/3500 with 5.9L 24-valve Cummins (late common-rail / 325 hp rating)

Important Notes

These injectors require proper ECM tuning and adequate fuel supply (quality lift pump and a healthy CP3) to realize the performance potential and maintain reliability. Supporting airflow upgrades are strongly recommended for higher power levels. Replace injector connector tubes/feed tubes at installation for best sealing and longevity.

Ideal for street performance, heavy towing, or moderate builds looking for a substantial, clean fuel increase without jumping to extreme competition sizing.
