DDP LB7-100 Remanufactured 100HP Injector Set – 60% Over

Unlock serious performance from your 2001–2004 6.6L LB7 Duramax with the DDP remanufactured 100HP injector set. This complete, balanced, and flow-matched set of 8 injectors delivers a 60% increase in fuel flow over stock, supporting 750–800 rear-wheel horsepower when paired with the proper supporting modifications.

Each injector is remanufactured using new OE-quality components and precision-calibrated for consistent fueling across all cylinders. The result is improved atomization, stronger mid-range torque, and the extra fuel volume needed for high-output street or competition builds.

Important Requirements These injectors require a modified or dual CP3 high-pressure pump, upgraded turbo(s), adequate lift-pump fuel supply, and custom tuning. They are not recommended for towing or lightly modified trucks. LB7 injector lines are prone to rust and restriction; replacement is strongly advised if the lines have not been changed in the last 40,000–50,000 miles.

Take your LB7 to the next level with a proven, high-flow remanufactured injector set built for serious Duramax performance.
