DDP 60 Percent Over 100hp Injectors w/Nozzles – Set of 8 (DDPNLB7-100) for 2001-2004 Duramax LB7

DDP 60% Over Injectors DDPNLB7-100 for Duramax LB7

The DDP 60% Over Injectors DDPNLB7-100 provide a major fueling upgrade for 2001–2004 GM 6.6L Duramax LB7 engines. This injector set is designed for high-horsepower performance builds that require significantly more fuel than stock injectors can provide. As a result, these injectors support serious power levels when combined with the proper supporting modifications.

This injector set is capable of supporting approximately 750–800 rear wheel horsepower in properly built Duramax engines. Because of the increased fueling capacity, these injectors are intended for high-performance applications rather than towing or daily work use.

High Performance Fuel Delivery

The DDP 60% over LB7 injectors increases fuel flow by sixty percent compared to factory injectors. This additional fuel supports larger turbochargers, higher boost pressure, and aggressive custom tuning.

With the proper supporting components, these injectors allow the engine to produce significantly more horsepower. However, increased fueling also requires upgraded air and fuel systems to maintain proper engine performance.

Supporting Modifications Required

These injectors require several supporting modifications to operate correctly. Trucks running this setup should use dual CP3 fuel pumps or a modified high-output CP3 pump. Larger turbochargers or compound turbo systems are also necessary to supply sufficient airflow.

Custom tuning is required to properly control the increased fueling. Without proper tuning, the engine will not perform correctly.

Because these injectors provide maximum fuel delivery, they are not recommended for towing applications.

Balanced and Matched Injector Set

The DDP LB7 injector set is sold as a balanced and matched set of eight injectors. Matching each injector ensures consistent fuel delivery across all cylinders.

This helps maintain smooth engine operation and prevents uneven fueling that can cause engine damage.

Each injector set includes a one-year unlimited mileage warranty, providing confidence in the quality and durability of the remanufactured components.
