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.
