FAQ
Are these injectors brand-new or reman?This listing is for a brand-new set (LLY-60SAC-SET). If you need reman options, contact CPP for availability.
Do I need a lift pump with 60% over injectors?While not strictly required, a quality lift pump (Airdog or FASS) helps maintain consistent supply pressure and filtration, which protects injectors and supports tuning.
Will these fit any LB7, LBZ, or LMM trucks?No. This set is LLY-specific (2004.5–2005). For other Duramax generations, shop CPP’s fuel system categories or ask us.
Do I need custom tuning?60% over injectors typically require appropriate calibration to meet your drivability and power goals. Consult your tuner for exact requirements.
