DDP LB7-ECO Economy Series Remanufactured Injector Set

Restore smooth performance and improve drivability in your 2001–2004 6.6L Duramax LB7 with the Dynomite Diesel Products (DDP) Economy Series remanufactured injector set. Designed as a practical upgrade for stock or lightly modified trucks, this matched set of eight injectors delivers a mild 10–20 rear-wheel horsepower gain along with noticeably better throttle response.

Each injector is remanufactured to tighter flow tolerances than original equipment and then balanced as a complete set. The result is smoother idle, more consistent operation, little to no smoke, and excellent fuel economy—without the need for extensive supporting modifications.

Key Benefits

• Mild 10–20 RWHP increase
• Improved throttle response
• Tighter-than-OEM balancing for smoother running

Fitment Fits 2001–2004 Chevrolet Silverado and GMC Sierra 2500HD/3500HD equipped with the 6.6L LB7 Duramax diesel.

What’s Included Complete remanufactured injector set (8 injectors). Typical installation hardware such as copper washers and O-rings is included with most sets.

Important Note LB7 high-pressure injector lines are prone to rust and can damage new injectors. If the lines have not been replaced within the last 40,000–50,000 miles, strongly consider installing a new line set at the same time.
