S&S Diesel LLY-10SAC-SET New Torque Master Injector Set

Upgrade your 2004.5–2005 Duramax LLY with the S&S Diesel Motorsport Torque Master Injector Set. These brand-new injectors deliver a true “stock-plus” fuel system upgrade engineered for stronger low-end torque, smoother idle, cleaner combustion, and reliable everyday performance—whether you’re daily driving, towing, or running mild performance mods.

Built on new injector bodies and finished with S&S’s proprietary nozzle honing process, the Torque Master (10-SAC) profile provides approximately 10% more flow than stock while maintaining excellent atomization and drivability. Every set is precision flow-matched and rate-shape aligned so all eight injectors deliver consistent fueling across the engine.
