Big Power for Serious Duramax Builds

If you're building your 2004.5 to 2005 Duramax LLY for performance and need injectors that can keep up with big horsepower goals, the Dynomite Diesel LLY-100 100HP Injector Set is a key piece of the puzzle. These remanufactured injectors flow 45 percent over stock and are capable of supporting up to 800 rear wheel horsepower with the proper setup. That kind of fueling is perfect for race builds, competition trucks, or aggressive street setups that go beyond the limits of stock hardware. Each set is sold balanced and matched to ensure smooth operation and consistent fuel delivery across all cylinders.

Built for Power Not for Towing

These injectors are not designed for heavy towing or daily workhorse duty. Instead, they’re made to deliver serious performance when paired with the right supporting mods. A modified or dual CP3 pump is mandatory, along with upgraded turbos and custom tuning to make the most of the additional fuel volume. When installed in the right build, they help unlock big gains in power, throttle response, and overall performance. If you're planning a high-output Duramax build and want an injector set that delivers clean, consistent fuel at high pressure, this setup has the strength and flow to match your goals.
