Chevy Duramax 01-04 LB7 Injector Set: Brand New Clean Custom injector set with SAC Nozzles. This injector set is intended for greater than 1,150+ RWHP applications. All Clean Custom injector sets are built to spec based on intended use and vehicle modifications.
Sold as balanced and matched set upon completion of custom injector waiver.
Note: The fuel injector lines on the LB7 are notorious for rusting and causing issues with the injectors. For this reason, we highly recommend replacing your injector lines while changing injectors if the lines have not been changed within the last 40,000-50,000 miles.
SAC Style Nozzle
NOTE TO ALL COMPETITORS:
When you’re pushing limits on the track or on the dyno, things can and do happen—even to the highest quality injectors. That’s why many of our top performing customers choose to order an extra injector (or two) as a backup. We know that nothing stings more than missing a round because you’re waiting on repairs when a quick swap could keep you on the track.
Our injectors are built for reliability and trusted by serious competitors across the globe, but if they ever need servicing, please know that testing and repairs are handled on a first come, first served basis. This means that in the busy spring and summer months, turnaround for custom injector repairs can run 2–4 weeks.

WHEN WILL I GET MY NEW INJECTORS?
We do not promise lead times on custom injectors or custom nozzles. With that said, we typically ship all custom items within 2-4 weeks after your order has been placed and you've completed the custom injector/nozzle worksheet.
