Stock replacement, remanufactured and performance injectors for the 2001 to 2004 LB7 Duramax. We carry Industrial Injection, S&S Diesel Motorsport, Exergy and DDP, in singles and full sets, plus Fleece injection lines and Industrial Injection install kits.

Choosing LB7 Injectors

  • Stock replacements: DDP and Industrial Injection stock injectors for daily drivers and work trucks. The Industrial Injection packages include lines and install parts.
  • Mild upgrades: Industrial Injection Dragon Fly and R1 to R4 (15 to 50 percent over) and Exergy 45 and 60 percent over. Good power with a tune on a stock turbo.
  • Big power: Industrial Injection R5 and R6, Exergy 100 to 500 percent over and S&S SAC00 and TorqueMaster injectors. These need custom tuning, fuel system upgrades and usually a bigger turbo.

Signs Your LB7 Injectors Are Failing

Rising oil level or fuel smell in the oil, white or black smoke, rough idle, hard starts and high balance rates all point to injectors. Because a leaking LB7 injector puts fuel in the oil, do not keep driving on bad injectors. Read our full LB7 injector guide.

Pair new injectors with a healthy LB7 fuel system and the right LB7 tuning. Shop all LB7 Duramax parts.

LB7 Injector FAQ

Should I replace all 8 LB7 injectors at once?

On a high mileage LB7, a full set is usually the better fix because the rest are close behind. A single injector can make sense on a low mileage set.

Do upgraded LB7 injectors need a tune?

Yes. Anything over stock flow needs a tune written for that injector to control smoke and EGT.

What are the signs of bad LB7 injectors?

Fuel in the oil, smoke, rough idle, hard starts and high balance rates are the most common signs.
