This remanufactured set delivers an extra 75 horsepower over stock, giving your 2011–2016 Silverado or Sierra 2500HD/3500HD the kind of throttle response and drivability that makes daily driving a lot more fun. Whether you’re after more low-end grunt or looking to stretch your truck’s legs on the open road, this matched and balanced set helps deliver smoother acceleration and more efficient fuel flow. While custom tuning is recommended to get the most out of the upgrade, it’s not required to feel the benefits. That said, for peak performance, pairing these injectors with upgraded turbos and proper tuning will help your build reach its full potential. Just keep in mind they’re not ideal for heavy towing unless you've already upgraded your turbo system. If you're looking to make a noticeable jump in power without jumping all the way into a race setup, these injectors hit the sweet spot.

Balanced Precision Built For Light Performance And Street Use

The Dynomite Diesel LML-75 30% Over Injector Set is engineered specifically for the 6.6L Duramax LML found in 2011–2016 GM 2500HD and 3500HD trucks. These remanufactured injectors flow approximately 30 percent more fuel than stock and are designed to support mild power upgrades up to an additional 75 horsepower at the rear wheels. Each set is sold as a matched and balanced group, ensuring consistent performance across all cylinders and reliable fuel delivery under light to moderate load. For optimal results, custom tuning is strongly recommended to fine-tune the injection timing and maximize efficiency, although the injectors will still operate under factory programming. While this set improves performance and fuel economy for street-driven applications, it is not recommended for frequent heavy towing unless the vehicle is equipped with larger-than-stock turbochargers. The additional fuel volume makes these injectors a solid choice for trucks running upgraded air systems and looking for better throttle response without stepping into competition-grade components. This product is diesel-specific and not approved for sale or use in California. For LML owners looking to upgrade with confidence, this kit offers a proven blend of power, reliability, and precision.
