2001-2004.5 GM/CHEVROLET 6.6L DURAMAX LB7 REMAN FUEL INJECTOR (NEW NOZZLES, NEW STATORS, NEW CONTROL VALVES, NEW INLET FITTINGS)
Fix fuel system issues on your 2001–2004.5 GM/Chevrolet 6.6L Duramax LB7 with this Remanufactured Fuel Injector, designed to restore proper injection timing, flow, and atomization. Known for common issues such as internal cracking and fuel dilution, LB7 injectors require reliable replacements—and this unit is fully remanufactured and flow-tested to meet OEM performance specs.
Every injector is reconditioned using a multi-stage process: ultrasonic cleaning, replacement of wear components, lapping of sealing surfaces, and calibration using high-pressure test equipment. The result is a high-quality injector ready to deliver OEM-level reliability and fuel efficiency without the high cost of a brand-new part.
The 8th digit of the VIN will identify which engine model you have. LB7 engines have "1" as the 8th digit of the VIN.
