FAQ
What does “100% over” mean on these injectors?It indicates the nozzle flow is roughly double stock. Actual horsepower gains depend on rail pressure, command, and duration, so tuning and supporting mods are required.
Are these brand new or reman?This listing is for a remanufactured set (S&S part: LMM-100SAC-R-SET). New sets are available separately.
Do I need a lift pump with 100% over injectors?Highly recommended. A quality lift pump helps maintain supply pressure and protects the high-pressure system, especially with larger-than-stock injectors.
Will this set fit other Duramax generations?No. This set is matched for the 2007.5–2010 LMM platform. Check our other Duramax injector categories for LBZ, LML, L5P, etc.
