Overview

The KC300x Stage 2 Gen 3 Turbo is the ultimate 100% drop-in turbo upgrade for the 7.3 Powerstroke platform. After years of in-house R&D, this turbo delivers faster spool, increased airflow, and superior reliability compared to previous generations and competing drop-in turbos on the market.

Designed for high horsepower applications while maintaining excellent street manners, the KC300x Gen 3 eliminates known weak points of the factory turbo and earlier KC designs—making it the most advanced drop-in option available.

Performance Design Details

The Gen 3 KC300x utilizes a 0.91 A/R turbine housing and 0.70 A/R compressor cover, replacing older, inefficient housing designs. Drawing inspiration from modern turbocharger technology, the flow path, volute shape, and material density were completely re-engineered.

Compared to the previous 0.84 and 1.0 A/R turbine housings, the new 0.91 A/R:

  • Spools quicker

  • Produces more usable top-end power

  • Maintains excellent drive pressure control

The redesigned bearing housing allows for 200% larger thrust bearings and significantly upgraded journal bearings, dramatically improving reliability at elevated boost and horsepower levels.


Injector & Turbo Sizing Guidance

This turbo is recommended for 205/30 up to 238/80 injectors.

  • Will operate on smaller injectors, but for 205/30 and smaller, we recommend the KC300x Gen 3 Stage 1.

  • Exact compressor sizing is proprietary, but rest assured:
    This turbo will outperform any other drop-in turbo on the market — guaranteed.

If you need specific sizing details, feel free to contact us and we’ll walk you through the best setup for your truck.


Fitment Information

  • Designed for 7.3 Powerstroke pickup trucks

  • Fits 7.3 vans with modification to:

    • Turbo intake boot

    • Downpipe

  • Will NOT fit OBS or E99 trucks without modification

  • Fitment with aftermarket fuel systems, plenums, or piping kits cannot be guaranteed


Optional Add-Ons & Recommendations

For best performance, we highly recommend:

  • Upgraded Up-Pipes

  • Upgraded EBPV Pedestal

  • Hydra Programming Chip

Exhaust Brake Notice

Some exhaust brakes may cause clearance or performance issues due to flapper-style designs that create excessive back pressure. Fitment and compatibility are the responsibility of the customer.


Finish Options & Lead Times

  • Turbos are sand cast by default

  • Optional polished compressor cover available for $250

    • 2-week lead time for polished covers

  • Powder coating may take up to 3 weeks before shipping

Super-great squeaky balls
Size: 6 packs
My dog (a so-far 30 lb Aussie) absolutely loves these balls. The squeakers in them are great, quite loud. If you hate squeaky toys, do not buy these balls. I love them. They bounce really well, too. My dog loves to jump in the air and catch them on the high bounce (good indoor fun). Also, these are literally the only toy that Remy does not tear apart and consume pieces of. She even tears the fuzz off of Kong tennis-type balls. I also like that because of the "spikes," they do not get icky with saliva. I think these balls would be good for any dog of any size. Highly recommended.
