Description
This Dynomite Diesel 250% over injector set fits the 2001-2004 Chevrolet Silverado and GMC Sierra 2500 HD/3500 with the 6.6L Duramax LB7. It targets LB7 owners who want a meaningful fueling increase over stock without stepping up to the largest injectors available.
The set is assembled from brand-new OE injectors rather than remanufactured cores and arrives balanced and flow-matched for the V8. Nozzles are six-hole SAC units at 158 degrees, and the injector bodies are modified to support the 250% over sizing.
This size is popular for hard-driven street trucks, tow rigs that also see spirited use, and moderately built LB7 engines where the goal is strong, repeatable power rather than a full competition setup.
It is not a direct stock replacement. Custom tuning and a capable fuel system are needed to realize its potential, and it is not for sale in California. The set carries a 3 year unlimited-mileage warranty. Confirm sizing with your tuner first, since Dynomite Diesel is not liable for problems from an incorrectly sized set.
For an LB7 that needs more than a mild injector but not maximum flow, the 250% over set is a well-rounded option with solid warranty coverage.
