S&S Diesel 325-10VCO-R-SET Remanufactured TorqueMaster Injector Set – 2004.5–2007 5.9L Cummins

Upgrade your late 5.9L Cummins with a true stock-plus injector set that delivers more torque when you need it most—without changing everyday drivability.

The S&S Diesel 325-10VCO-R-SET is a complete set of six flow-matched, remanufactured TorqueMaster injectors designed specifically for 2004.5–2007 Dodge Ram 2500/3500 trucks with the 5.9L 24-valve common-rail Cummins (325 hp engines). These are not radical high-flow injectors. TorqueMaster is S&S Diesel Motorsport’s refined “stock-plus” solution that increases fuel delivery roughly 10% over stock and adds measurable torque under full-load conditions (towing, hard acceleration, or heavy pulling) while maintaining near-stock behavior at idle, part-throttle, and cruise.

Why TorqueMaster?

S&S proprietary internal modifications and nozzle work improve injection rate shape and fuel delivery under high demand. The result is sharper response and extra torque when the truck is working hard, yet the injectors retain the clean, efficient characteristics of a quality stock set for daily driving and fuel economy.

Key Features

• Complete flow-matched set of 6 remanufactured injectors
• Nozzles flow-matched to within 1% variance (OE standards)
• Injectors balanced as a set for smooth idle and even cylinder fueling
• Proprietary nozzle honing process for consistent, clean spray holes
• VCO-style nozzles matched to the late 5.9 piston bowl geometry
• Body modifications that improve injection rate shape while remaining a direct-fit replacement
• Built on high-quality remanufactured bodies and tested to rigorous S&S standards
• Direct drop-in replacement — no supporting modifications required for stock or lightly modified trucks

Fitment

• 2004.5–2007 Dodge Ram 2500 / 3500
