This Exergy diesel fuel injector set is engineered for the verified 6.6L Duramax LB7 applications listed below. It is selected by exact manufacturer part number E01 10106, not by appearance alone. Confirm the complete vehicle, engine family, production split, fuel-system configuration, and calibration requirements before ordering. Have your original or aftermarket injectors left you stranded? Are you looking for an increase in power without sacrificing drivability or reliability? Well, look no further than our 45% over fuel injectors! The nozzles are enlarged using abrasive flow honing technology and are hydraulically flow matched to less than 1%. Each nozzle undergoes four separate quality control checks throughout the process before being installed back onto the injector. All factory nozzle LB7 injectors are equipped with the latest DLC coated needle design to increase longevity. All components are built and tested on specialized equipment designed and built in-house at Exergy. Every 45% over injector set is tested at multiple calibration

Frequently Asked Questions
Will Exergy E01 10106 fit my Chevrolet Silverado 2500 HD?
It fits only the year range and engine application shown in the fitment table. Confirm the engine family, production split, fuel-system configuration, and exact Exergy part number before ordering.
Do these injectors require calibration or tuning?
Modified-flow injectors generally require matching engine calibration. Confirm injector flow, nozzle configuration, engine platform, fuel-system condition, and tuning requirements before installation.
Should the fuel system be inspected before installation?
Yes. Diagnose contamination, low-pressure supply, rail-pressure faults, damaged lines, and related injector or pump issues first. Installing a new component without correcting the cause can damage the replacement part.
Installation Instructions
Follow the current Exergy instructions and vehicle service information for this exact part number. Work only on a clean, depressurized fuel system, cap open lines immediately, use new required seals, lubricate seals only as specified, and torque fittings and components to the published values. Prime and bleed the system correctly, check for leaks, verify commanded and actual rail pressure, and complete any required calibration before operation. Professional diesel-fuel-system installation is recommended.
