Inject Serious Power Into Your LLY Duramax

If you’re building a 2004.5 to 2005 Duramax and aiming for high horsepower, the Dynomite Diesel NLLY-150 injector set is a key piece of the puzzle. These are brand new injectors—not remanufactured—and they come fitted with 60 percent over nozzles that provide a major jump in fuel flow. That extra flow is what opens the door to serious power gains, especially when paired with upgraded turbos, dual CP3 pumps, and a solid tuning setup. With the right supporting mods, this injector set is capable of supporting up to 1,000 horsepower at the wheels, making it ideal for competition builds or performance-focused weekend rigs.

Built for Precision, Not for the Street

This isn't the kind of upgrade you throw into a daily driver. Each injector in this set is carefully balanced and matched to ensure consistent fuel delivery across the entire engine. That balance is especially important when you're dialing in a custom tune and pushing your truck to its limits. Internal calibration upgrades help deliver smoother performance under throttle, reducing hesitation and improving throttle response. Designed specifically for the LLY 6.6L Duramax in 2500HD and 3500HD models, this injector set gives builders the fuel they need without cutting corners. Just keep in mind, it’s not emissions compliant and isn’t legal for use in California, but for off-road builds or track-prepped trucks, it’s a serious step toward hitting your performance goals.
