Serious Fuel for Big Power Builds

If you're putting together a high-horsepower Duramax and looking for injectors that can keep up, the Dynomite Diesel LLY-150 Reman Injector Set is built to handle the job. Designed for 2004.5 to 2005 GM Silverado and Sierra 2500HD/3500HD trucks with the 6.6L LLY Duramax, this set features 60 percent over nozzles and internal calibration upgrades to deliver significantly more fuel than stock. These injectors are fully remanufactured, then balanced and flow-matched as a set, ensuring consistent performance across all cylinders. With the right supporting mods, they’re capable of fueling up to 1,000 rear wheel horsepower—making them a strong foundation for race builds, sled pullers, or high-output drag trucks.

Not for the Daily Driver Crowd

This injector set is for drivers who are building with purpose. You’ll need dual CP3 pumps or a modified fuel system, a larger turbo or compound setup, and custom tuning to get the full potential out of these injectors. They’re not recommended for daily-driven street applications because of how much fuel they move, but if you're chasing serious power at the track or on the pull line, they fit the bill perfectly. These aren’t just big-flow injectors—they’re precision-calibrated components built for aggressive fueling and hard use under load. Just keep in mind they’re not emissions compliant in California, so check your local regulations before you buy.
