01-04 GM LB7 6.6L Duramax DDP 100HP 60% Over Fuel Injector Nozzle Set


Duramax 01-04 LB7 Nozzle Set: Full set of new injector nozzles flowing at 60 percent over, capable of 750 RWHP with proper supporting modifications.

Sold as a matched set with copper sealing washers.

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 or nozzles if the lines have not been changed within the last 40,000-50,000 miles. The part number for our brand new line set is: DDP LB7LINE-SET

IMPORTANT NOTE:  All nozzles should be installed and the injectors calibrated by a professional shop that is familiar with calibrating over sized injectors.  Due to the massive variations in calibrations of injectors from other manufacturers, we cannot guarantee you will see the stated horsepower gains unless the nozzles are installed by Dynomite Diesel and all other supporting modifications are in place.
