- SAC nozzles precision-honed; sets flow-matched for consistent output.
- Built and verified on industry-leading test equipment for durability and repeatability.
- Ideal for high-horsepower builds (supporting major airflow, turbo, and fueling upgrades).
Fitment
- 2019–2024 Ram 2500/3500, 6.7L Cummins 24-valve (common-rail).
- Direct-fit for 2019+ 6.7C19 injector architecture.
What’s Included
- (6) New S&S Diesel 100% Over Injectors – 6.7C19-100SAC-SET
- Pre-installed SAC nozzles, flow-matched as a set
- O-rings/seals as supplied by S&S
Recommended Supporting Parts
To get the most from 100% over injectors, pair with sufficient pump capacity, clean filtration, and proper air supply. Shop CPP Diesel supporting parts below:
- Fuel Injectors & Install Parts
- CP3 Injection Pumps (stroked or dual-fueler setups recommended)
- Fuel Filtration & Lift Pump Systems
- Turbochargers & Compounds (to provide the airflow a 100% set demands)
- Injector Install Kits & Seals
Helpful Notes
- 100% over refers to nozzle flow over stock. Actual fuel output also depends on rail pressure and commanded duration.
- Professional calibration/tuning and adequate air/fuel supply are required for best results.
- Use high-quality filtration and clean procedures during install.
FAQs
How much power can a 100% over injector set support?
Power potential depends on turbo(s), pump capacity, fuel quality, and tuning. In properly matched setups, 100% over injectors support large gains suitable for competition-level builds.
What does “100% over” actually mean?
It indicates the nozzle flow is roughly 100% higher than stock. Real output varies with rail pressure, injection duration, and mapping, but it’s a good sizing guideline for fuel capacity.
Are these remanufactured injectors?
No. This set uses brand-new injector bodies with internal body modifications and SAC nozzles as specified by S&S.
Do I need an upgraded lift pump and CP3?
Yes—100% over injectors require strong supply and high-pressure fuel to perform correctly. We recommend a quality lift pump/filtration system and an upgraded or additional CP3.
Is custom tuning required?
Strongly recommended. Proper calibration optimizes pulse width, timing, and rail pressure for clean power and reliability.
