Product Description
S&S Diesel 325-200SAC-SET 200% Over Injector Set – NEW – 2004.5–2007 Cummins 5.9L 24V (Set of 6)
Turn your late 5.9L common rail into a contender. This brand-new S&S Diesel Motorsport 200% over injector set uses SAC nozzles and OE-level flow matching to deliver clean, consistent fueling when your build demands serious fuel.
- Brand-new bodies, not take-outs or mystery cores
- SAC nozzles with a proprietary honing process for ultra-clean holes
- Matched to OE standards: nozzles flow-matched to ≈1% per set; injectors matched to ≈3% for cylinder-to-cylinder balance
- Race-level flow (200% over) to support big single or compound turbos and high-output CP3s
- Built to spec for the target flow with injection rate-shape alignment for drivability at this size
Fitment
- 2004.5–2007 Dodge Ram 2500/3500, Cummins 5.9L 24-valve (late common rail)
- Direct replacement for late-year (2004.5+) 5.9L CR injectors
What’s Included
- (6) New S&S Diesel Motorsport 200% over common-rail injectors – part 325-200SAC-SET
- Set is flow-matched and ready to install (tuning & supply pump required for best results)
Recommended Supporting Parts
Pair these injectors with proven components to keep rail pressure stable and minimize install issues:
- 03–07 Cummins CP3 Injection Pumps (stock–14mm)
- Common Rail Injector Installation Kit (seals & hardware)
- Injector Return Line – 5.9L (03–07) & Return Check Valve
- 5.9L Cummins Injector Category & 04.5–07 Injector Category
Helpful Notes
- Fuel System: A healthy, adequately sized lift pump/filtration and a high-output CP3 are strongly recommended for 200% injectors.
- Tuning Required: Custom ECU calibration is mandatory to control smoke and EGT with this flow rate.
- Cores: S&S programs require core return
FAQ
How much power can 200% injectors support?With sufficient air and pump, 200% over injectors support very high horsepower builds. The limiting factors are turbo(s), CP3 capacity, and tuning. Plan for a stout single or compounds plus a 10–14 mm CP3.
Do I need a bigger CP3 for these?
Yes. For 200% over, a high-output or stroker CP3 (and a strong lift pump) is strongly recommended to maintain commanded rail pressure under load. See our 03–07 CP3 options.
Are these brand-new or reman?
This listing is NEW injectors in a set of six. If you need reman, see our S&S reman options in the 04.5–07 injector category.
What’s special about S&S SAC nozzles and flow matching?
SAC nozzles are honed and matched to tight tolerances, and each set is flow-balanced so cylinders fuel evenly—critical at 200% sizes for drivability and reliability.
Will these fit early 2003–early 2004 trucks?
No. This “late 5.9” set is for 2004.5–2007. Early 03–early-04 use a different injector spec. Check the 5.9L injector category for the correct year range.
