KC Turbos KC300x G3 Stage 2 Turbo 99.5-03 Ford 7.3L PowerstrokeThe KC300x Stage 2 Gen 3 Turbo is a high performance, drop in upgrade for 7. 3L Powerstroke pickup trucks running larger injectors and higher horsepower goals. Designed through years of R&D and extensive dyno testing, this Gen 3 turbo delivers faster spool, increased airflow, and improved durability over previous KC300x designs and competing drop in turbos.

The KC300x Stage 2 Gen 3 Turbo is a high-performance, drop-in upgrade for 7.3L Powerstroke pickup trucks running larger injectors and higher horsepower goals. Designed through years of R&D and extensive dyno testing, this Gen 3 turbo delivers faster spool, increased airflow, and improved durability over previous KC300x designs and competing drop-in turbos.

At the core of the Stage 2 is a redesigned Gen 3 7x7 SXE-style compressor wheel with upgraded aerodynamics and extended-tip technology, paired with a thick-shaft SXE-style turbine wheel built to handle higher boost and horsepower levels. The modern 0.70 A/R ported compressor cover and redesigned 0.91 A/R turbine housing utilize advanced volute geometry, an improved MAP groove, and an anti-surge design to spool faster than older 0.84 A/R housings while flowing more air than previous 1.0 A/R setups. Delivering strong low-end response with excellent top-end power.

Reliability is a major focus of the Gen 3 platform. This turbo features 200% larger thrust and journal bearings, a thicker turbine shaft to prevent 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, eliminating common failure points found in stock and earlier turbo designs.

The KC300x Stage 2 installs as a 100% drop-in replacement for 7.3L Powerstroke pickup trucks and includes all required gaskets, O-rings, and an upgraded 4" intake boot for improved fitment. A high-flow non-EBPV outlet flange improves exhaust flow, while the redesigned round-top wastegate actuator provides more consistent boost control.

This turbo is recommended for trucks running 205/30 through 238/80 injectors, making it ideal for aggressive street, towing, and performance builds that demand maximum drop-in power. For smaller injector setups, the KC300x Gen 3 Stage 1 is the better match.

I was so sad when my size of the woman’s specific no show invasion socks were sold out and there not making more. But these had around the same size, not uncomfortable, and a lot better then most I can find if still a step down from the previous. Still love them! A good buy
