S&S Diesel Motorsport 305-40SAC-R Remanufactured 40% Over Injector Set (Set of 6)
Upgrade your early 5.9L Cummins with a precision-matched set of S&S Diesel Motorsport remanufactured 40% over injectors. These injectors deliver approximately 40% more fuel flow than stock while maintaining excellent atomization, balance, and drivability.
Key Features
- 40% over stock flow for increased fuel delivery and power potential
- SAC nozzles with S&S proprietary honing process for consistent, clean nozzle holes
- Precision flow-matched set: nozzles matched within ~1% variance and injectors within ~3% variance across the set
- Injection rate shape (profile) aligned for smoother operation
- Built using high-quality remanufactured Bosch bodies and industry-leading components
- Thoroughly tested on advanced equipment to ensure consistent performance across all six injectors
A properly balanced set like this helps deliver smoother idle, more even cylinder loading, improved efficiency, and cleaner combustion compared to unmatched injectors.
Fitment
- 2003–2004 Dodge Ram 2500 / 3500
- 5.9L Cummins 24-valve common-rail (Early / 03–04 style injectors only)
Note: These will not fit 2004.5–2007 (Late) 5.9L applications.
Important Notes
- Sold as a complete matched set of 6
- Core return required
- Proper ECM tuning is strongly recommended
- Supporting fuel system upgrades (lift pump, filtration, etc.) are advised for best results and longevity
S&S Diesel Motorsport injectors are known for tight quality control and consistent real-world performance. This 40% reman set is an excellent choice for street, towing, or moderate performance builds looking for reliable extra fueling without jumping to extreme sizes.
