Dynomite's 75 horsepower injectors are notorious for providing a very noticeable increase in power, and typically in MPG's as well, while being extremely clean out the tailpipe. There's no better way to make your Duramax Fly!

With the Allison 5 and 6 speed, the Duramax is already fun to drive. Why not add an additional kick with some Dynomite injectors? This injector set will deliver an additional 75 horsepower for additional pulling and play power, and will typically net a noticeable increase in fuel economy, as well, yet are capable of supporting 675 RWHP with supporting modifications. Whether your original LB7 injectors have failed and are in need of replacing, or you just want a power increase, these are a great addition to any Duramax!

Dynomite Diesel K-Factor Injector Nozzles – Precision. Performance. Power.
When it comes to injector nozzles, it’s not just about how much fuel you can dump, it’s about how efficiently you can deliver it. That’s where Dynomite Diesel’s K-Factor technology sets itself apart from the pack. Most aftermarket nozzles rely on standard EDM machining, quick, cheap, and dirty. But Dynomite Diesel isn’t “most.” Instead of stopping at EDM, they take it further with Advanced Flow Machining (AFM) and precision honing that smooths out imperfections, polishes internal surfaces, and radii the inlet of each orifice. The result? Clean, consistent spray patterns that make more usable power, not just smoke and heat.

Why K-Factor Nozzles Matter:

  • Removes Flow Restriction at Orifice Entrance: Eliminates the natural low-pressure zone where fuel enters the orifice, allowing smoother and faster flow.
  • Better Fuel Atomization: Fine mist = cleaner burn. That means less black smoke, lower EGTs, and more bang per drop of fuel.
  • Delivers More Fuel at Same Pressure: Pushes more volume through a smaller hole, yes, really. It’s about optimized shape, not just size.
  • Reduces Turbulence: Smoother internal geometry minimizes swirl and pressure loss inside the nozzle, no flow drama here.
  • Improved Power and Efficiency: With better atomization comes better combustion, and that means more horsepower, cooler temps, and increased fuel mileage.
  • Less Smoke, More Go: Bigger isn’t always better, smoky, hot tunes waste fuel. K-Factor nozzles strike the perfect balance for performance builds and daily drivers alike.

Dynomite starts with blank nozzles or custom machined pieces based on specific spray angle requirements. Each nozzle goes through a proprietary honing process, no shortcuts. The end result? A nozzle that not only flows more but does so smarter, delivering cleaner, cooler, more efficient power than the competition. Whether you're building a mild street truck or an all-out track monster, K-Factor Nozzles give you the edge where it counts, in real world performance.

Great item
I have several of these for my German Shepherd and Hound dog. While the Shepherd can still manage to get this apart it takes a lot longer than other chew toys.

Would not recommend
I bought this for my bulldog/boxer dog thinking that it was completely made of leather but it’s not. It has an inch of felt type material between two very thin leather pieces which makes it easy for her to chew on, becoming soft very quickly and then falls apart. We took it away from the dog the first day and threw it away because we didn’t want her swallowing felt type material.
