These injectors are brand new—not remanufactured—and feature nozzles that flow 150 percent over stock. That means you're moving serious amounts of fuel, but with control and precision thanks to internal calibration upgrades done in-house by the experts at Dynomite Diesel. When paired with a proper setup—including dual CP3s, upgraded turbos, and custom tuning—this injector set is capable of supporting up to 1,400 rear wheel horsepower. It's designed for trucks built with racing, sled pulling, or dyno domination in mind.

Serious Injectors for Serious Builds

Each set is sold fully matched and balanced to ensure consistent fuel delivery across all eight cylinders, which is critical when you're working at the edge of what your engine can handle. These aren’t just oversized nozzles slapped onto stock bodies—they’re engineered for competition and tested to hold up under extreme pressure. Keep in mind, this set is not meant for daily use or casual street driving. It’s for owners who understand their fuel system inside and out and are building with intention. While it’s not CARB approved and can’t be sold in California, it’s a perfect fit for anyone putting together a purpose-built powerhouse. If you're committed to building an all-out LMM, these injectors are an essential part of the equation.
