FAQ
What does “TorqueMaster 10-SAC” mean?It’s S&S’s LLY nozzle/flow profile aimed at a “stock-plus” upgrade with crisp atomization and balanced fueling across the set.
Is tuning required with TorqueMaster injectors?For most stock-turbo, stock-pump LLY trucks, these injectors operate well without custom tuning. Custom tuning may optimize smoke control and drivability on modified setups.
Are these new or reman?This listing is for a new set (LLY-10SAC-SET). S&S also offers reman options; see our S&S brand page for alternatives.
Do I need any special install parts?We strongly recommend fresh seals and an install kit, plus inspecting/refreshing return lines while the rails and lines are off.
