KC Turbos KC300x G3 Stage 1 Turbo 99.5-03 Ford 7.3L PowerstrokeThe KC300x Stage 1 Gen 3 Turbo is a true drop in performance upgrade for the 7. 3L Powerstroke, delivering faster spool, increased airflow, and proven power gains without sacrificing reliability. Developed through years of R&D and dyno testing, this Gen 3 design outperforms previous KC300x versions and other drop in turbos on the market.

The KC300x Stage 1 Gen 3 Turbo is a true drop-in performance upgrade for the 7.3L Powerstroke, delivering faster spool, increased airflow, and proven power gains without sacrificing reliability. Developed through years of R&D and dyno testing, this Gen 3 design outperforms previous KC300x versions and other drop-in turbos on the market.

At the core is a redesigned Gen 3 7x7 SXE-style compressor wheel with upgraded aerodynamics, paired with a thick-shaft SXE-style turbine wheel built to handle higher boost levels with improved durability. The modern 0.70 A/R ported compressor cover and 0.91 A/R turbine housing feature advanced volute geometry, an improved MAP groove, and anti-surge design. Allowing the turbo to spool faster than older 0.84 A/R housings while flowing more air than previous 1.0 A/R designs. The result is stronger low-end response with improved top-end power.

Reliability is significantly enhanced with 200% larger thrust and journal bearings, a thicker turbine shaft to reduce deflection, and a redesigned bearing housing with an integrated cast-iron backing plate for increased rigidity under extreme heat and pressure. A steel thrust insert further reinforces critical wear areas, addressing common failure points found in stock turbochargers.

This turbo installs as a 100% drop-in replacement, requiring no modifications. It includes all necessary gaskets, O-rings, and an upgraded 4" intake boot for improved fitment. A redesigned round-top wastegate actuator improves boost control, while the high-flow non-EBPV outlet flange enhances exhaust flow.

The KC300x Stage 1 Gen 3 is well suited for daily driving, towing, and performance-oriented builds seeking maximum power from a true drop-in turbocharger.

The only one I'll use!
As the title says, this is the brand to get!! It's fast-acting, doesn't give me weird dreams like some do, and I never wake up feeling groggy.

Works wonders
I've been buying these for well over a year now as Subscribe and Save. I work 12 hour overnights as a nurse. My sleep schedule normally gets messed up. I would have no problem falling asleep but would wake up only a few hours later which is not good when you have work again that night. We buy these on Amazon due to the great price and the fact that they are extended release which helps keep me asleep longer. When I take 1 or 2 of them, I am able to sleep about 7-8 hours which is great. I take this both when I sleep during the day and sleep during the night. It helps me sleep no matter when and I am able to adjust my sleep schedule often. I have recommended them to many.

Works quite well, dose still a bit high for me
Used to take the Natrol 5mg slow release, now that I can compare these 2, I love this more. It doesn't make me feel too edgy, it's quite relaxing actually. I still have to halve the dose as the full dose makes me groggy the next day. Where the Natrol gave me very vivid, but not unpleasant dreams, these don't make me dream as vividly. It does take a bit longer to get me to sleep, but once asleep, your asleep. Highly recommend, once I finish this bottle, I'd get the 2mg tr next time, as a lower dose works better for me.

seems to work just fine
Helps me sleep. I also use Mg, B complex and medical cannabis oil before bed. My sleep isn't great otherwise here in the good ol' USA (unlike in Europe where I sometimes go for complicated issues/not vacation; which indicates issues with the much higher radiofrequency exposure allowed in the US than in the European country where I sleep like a happy baby). Just wait for 5G, then I probably need to reinvent my sleep protocol if I want to get any rest. But well, with the 5G impact on the biosphere, we may not be here much longer then. That means we better stop 5G before it's all roleld out.
