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.

Good purchase
Style: 3 Pound, Pair
These are just the right weight for me to start gaining muscle back in my arms, after a large weight loss. They are of good quality, they are covered in a nice rubber like coating that is soft to the touch. They are small enough that i can take them with me when I travel. My dog has got hold of them a couple times and played with them, and they held up just fine without any damage.

Solid, grippy, and they don’t roll away!
Style: 10 Pound, Pair
I bought these because I’m finally trying to build a consistent home workout routine and didn't want to drop a fortune on name-brand weights. I’ve been using this 10lb pair for about a month now for everything from overhead presses to lunges, and honestly, they’re exactly what I was looking for. The Pros: • That Neoprene Grip: The coating is fantastic. Even when my hands get pretty sweaty halfway through a workout, I don’t feel like I’m going to drop them. It’s a much "softer" feel than cold metal or hard plastic. • The Hex Shape: This is a small detail that makes a huge difference. Since the ends are hexagonal, they don't roll across the floor when I set them down between sets. They also stay put if I’m using them for "renegade rows" or floor work. • Compact Size: They aren’t bulky. I can easily shove them under my bed or in the corner of the closet when I’m done. • No Weird Odor: I was worried they might smell like a tire factory (which happens with some rubber-coated weights), but these had almost no scent right out of the box. The Cons: • Handle Diameter: The handles are a little on the thicker side. I have medium-sized hands and it’s fine, but if you have very small hands, they might feel a bit chunky to wrap your fingers all the way around. • Color Scuffs: The navy blue looks great, but if you clank them together or drop them on concrete, the coating can scuff or show dust pretty easily. The Verdict: If you just need a reliable set of weights for HIIT, Pilates, or general strength training, these are a no-brainer. You're basically getting gym-quality equipment for a fraction of the price. I’ll probably be back for the 15lb set in a few months!

Great Water Bottle!
Color: Off Road, Size: 30 Ounces
I was looking for an insulated water bottle that would actually fit in a standard cup holder. I decided to try the Owala FreeSip Sway Insulated Stainless Steel Water Bottle. Upon receiving it, I noticed that it felt solid in my hand. The mechanism worked very smoothly with a simple button press opening the lid. Once open, you can choose to either use the included straw or tip the bottle and drink from the chug spout. In addition to it fitting in my cup holder, I needed it to be leak proof. This bottle is leak proof, and the spout can be locked by engaging a lock in the back. The rugged flip handle is also a convenient way to carry the Owala when it's not in the water bottle holder on my backpack. I hand wash the body of the bottle, but the top disassembles easily and can go right in the dishwasher when I want a deep cleaning. The bottle has a wide opening, so it is very easy to clean the inside. This has quickly become my favorite water bottle due to its ease of cleaning, good insulation, ability to fit in my cup holder, solid construction and materials, and the option of using the straw or chug spout. I have the 30 ounce bottle, but I am going to be picking up a 40 ouncer also. You won't regret purchasing one! I have used the bottle for a couple of weeks now, and here are my observations: It has gone on two camping trips, and it has proven to be durable. I have placed the Owala on its side on my passenger seat (just to test it...it fits perfectly in my car's cup holder!). It did not leak a single drop on a long road trip. On my camping trip, the water in the bottle was still ice cold the next morning, so it keeps cold beverages very cold!

The Perfect Bottle
Color: Dreamy Field, Size: 40 Ounces
I do not leave reviews, but I had to for this. This is the PERFECT water bottle. It has a handle, it's leak-proof, with a lock, so you don't have to worry when your baby decides to play with the bottle and tips it over -- there won't be a spill! Straw and sip option are perfect and I love that the straw is inside the cup so I don't have to worry about my kids hurting themselves when they drink from the cup. 40 oz is a great size, holds a lot of water but tapered bottom perfectly fits in the cup holder. So easy to use, my 4 year old has no issues. Cleaning takes 3 minutes. I recommend to absolutely everyone.
