Product Details

The Industrial Injection 412603 is a complete remanufactured injector kit designed for the 2001–2004 Duramax LB7 6.6L diesel engine.

The LB7 Duramax was notorious for injector cup and tip failures, making a full injector replacement one of the most common and critical repairs on this platform. Industrial Injection's remanufactured Bosch injectors are rebuilt to OEM specifications, restoring proper fuel atomization, combustion efficiency, and overall engine performance.

Kit Contents & Features:

  • 8x Stock-output remanufactured Bosch LB7 fuel injectors
  • New injection lines included for a complete refresh
  • Full installation hardware kit included
  • Rebuilt to OEM Bosch specifications for stock fuel delivery performance
  • Designed specifically for 2001–2004 6.6L Duramax LB7 engines
  • Remanufactured by Industrial Injection, a trusted name in diesel performance

Installing a complete injector set with new lines and hardware eliminates the need to source individual components and ensures all injectors are matched and performing consistently. This kit is the straightforward, all-in-one answer for LB7 injector replacement.
