When More Fuel Means More Power With Control

If your Duramax build is ready for serious power, the Industrial 0986435409-R5 75% Over Injector is built to keep up with your goals. This isn't just a cleaned-up stock injector, it’s an OEM reman unit that’s been modified for high-output performance through precision extrude honing and flow balancing. That means you get significantly more fuel flow while maintaining the consistency and reliability you need under load. Whether you’re chasing big dyno numbers or putting down serious torque for competition, these injectors help your truck breathe and burn more efficiently. They’re a perfect fit for heavily tuned trucks with upgraded turbos or other major performance mods. Even with all that added flow, they install like stock and come with fresh o-rings and a copper crush washer for a proper seal. Backed by a one-year unlimited mileage warranty, this injector delivers dependable power where it counts most.

Precision Flow Matched Injectors Engineered For Race Level Demands

The Industrial 0986435409-R5 75% Over Injector starts as a factory OEM remanufactured unit and is then enhanced using extrude honing to increase flow while preserving internal integrity. Each injector is carefully balanced and matched to ensure consistent performance across all cylinders, which is especially important at higher horsepower levels. The 75% over flow rating translates to approximately 20 LPM, making these injectors a strong fit for trucks running aggressive tuning and large turbo upgrades. Designed specifically for the 2011-2016 LML Duramax, these injectors drop into place without modification and maintain OEM fit and form. Industrial Injection ensures that each set meets strict calibration standards for proper fuel delivery, timing, and spray pattern control. With more fuel volume comes more responsibility, which is why these injectors are backed by expert testing and a proven warranty. For serious builders who need more than just average flow numbers, this set is built to deliver consistent results under real-world performance conditions.
