Thumbnail Filmstrip of 5.9 Cummins 45% Over Reman Injector S&S Diesel 325-45SAC-R-SET - Dealer Images
Upgrade the performance of your 5.9L Cummins engine (2004.5–2007 models) with the S&S Diesel 325-45SAC-R-SET 45% Over Reman Injectors. Designed to deliver superior fuel atomization, precise fuel metering, and optimal combustion efficiency, this set bridges the gap between raw power and refined reliability. Utilizing advanced SAC nozzles treated with a proprietary honing process, every unit features exceptionally clean and uniform orifice holes. This careful crafting reduces wear over time and ensures smooth fuel delivery under high-pressure conditions, offering a distinct upgrade over standard stock configurations.
High-Precision SAC Nozzles: Treated with a proprietary honing process for clean, consistent orifice holes that enhance atomization.
Tight Nozzle Flow Specs: Nozzles are flow-matched within a tight 1% variance per set using Viscor SAE-J967 fluid at 40°C and 100 bar, following rigorous OE standards.
Comprehensive Injector Matching: Fully assembled injectors are flow-matched within a 3% variance per set across 4 distinct pressure and energizing points using Viscor SAE-J967 fluid at 40°C.
Optimized Injection Profiling: Features aligned rate shapes, ensuring each injector build specification is custom-matched directly to its specific nozzle flow rate.
Internal Body Modifications: Models rated at 250% (3,700 cc/min) and higher include specialized internal modifications designed to mitigate the slower opening and closing times caused by increased nozzle flow, resulting in an improved injection rate shape.
By maintaining strict tolerance standards across multiple energizing points, these remanufactured injectors prevent cylinder imbalances and maintain smooth engine operation throughout the RPM range. The custom matching of the injector build to the nozzle flow rate guarantees that increased fuel volume does not compromise hydraulic efficiency. S&S Diesel's meticulous testing and engineering result in a drop-in fueling solution that provides predictable power, balanced combustion, and maximum output for your heavy-duty Cummins build.
