S&S Diesel LLY-10SAC-R-SET Reman TorqueMaster Injector Set

Upgrade your LLY Duramax with the S&S Diesel Motorsport TorqueMaster remanufactured injector set (LLY-10SAC-R-SET). This complete set of 8 injectors delivers a mild “stock-plus” fuel flow increase over factory while prioritizing low-end torque, smooth drivability, and long-term reliability—ideal for daily drivers and towing applications.

Key Features

• SAC10 TorqueMaster nozzle design for improved fuel delivery and throttle response without sacrificing street manners
• Proprietary nozzle honing process for clean, consistent orifices
• Nozzles flow-matched to 1% variance and complete injectors flow-matched to 3% variance across the set (tested at multiple pressure/energizing points with aligned injection rate shapes)
• Built on genuine Bosch remanufactured bodies for OE-level durability
• Direct-fit replacement with factory-style connectors

Fitment

2004.5–2005 Chevrolet Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD with 6.6L Duramax LLY engine.

These injectors are engineered as a high-quality stock alternative that exceeds factory flow while maintaining excellent refinement and efficiency. Most stock or mildly modified trucks run well without custom tuning (a calibrated tune can further optimize smoke and response if desired). Backed by S&S Diesel’s 2-year unlimited-mileage warranty.

Perfect for restoring or improving performance on high-mileage LLY trucks that need reliable, balanced fueling.
