Upgrade your 2007.5–2018 6.7L Cummins with the Stainless Diesel S300 VGT Turbocharger Replacement Kit featuring 5Blade Mafia technology. Lower EGTs, maximum reliability, and that legendary Stainless Diesel whistle.

If you’ve owned or worked on a 2007.5–2018 6.7L Dodge Cummins long enough, you already know the story. Factory Variable Geometry Turbochargers (VGTs) offer decent low end response out of the box, but over time, soot buildup, sticking nozzle vanes, failed electronic actuators, and high exhaust gas temperatures (EGTs) turn daily driving and/or towing into a headache.

When your factory VGT gives out, you’re faced with a choice: spend your hard earned money replacing it with another failure prone stock unit, or upgrade to a simpler, stronger, and more reliable setup.

That’s why we designed and created our new Stainless Diesel S300 VGT Turbocharger Replacement Kit.

Why Ditch the Factory VGT?

Stock VGTs use complex internal moving parts and electronic actuators to constantly adjust turbine flow. While great in theory, in the harsh environment of a diesel exhaust system, those moving parts are prone to:

• Sticking Vanes & Soot Buildup: Leading to loss of boost, sluggish acceleration, or sudden overboost conditions.

• Actuator Failures: Leaving you stranded or forced into limp mode.

• Excessive Backpressure & Heat: Higher EGTs that stress your engine during heavy towing or spirited driving.

By converting to an S300 fixed geometry (Non-VGT) turbo setup, you eliminate those possible mechanical issues altogether, giving you simple, predictable performance that stands up to heavy use (and abuse).

Why the Stainless Diesel S300 VGT Turbocharger Replacement Kit?

Engineered specifically for 2007.5–2018 6.7L Cummins trucks, this conversion kit brings together durability, reliability, a simple installation process, power delivery, and the performance that Stainless Diesel is known for.

1. Powered by 5Blade Mafia Technology

At the heart of this kit is our signature 5Blade Mafia compressor wheel design. Designed for maximum air velocity and efficiency, it delivers fast throttle response, lower operating temperatures, and the legendary Stainless Diesel turbo whistle.

2. Lower EGTs & Reduced Drive Pressure

Fixed geometry S300 turbine housings flow much more efficiently than a restrictive VGT. That means significantly lower exhaust gas temperatures under load and a safer, cooler operation when hauling heavy trailers or pushing high horsepower.

3. Simplified Reliability

No electronic actuators to replace. No internal vanes that build up with carbon. Just heavy duty hardware built to perform consistently for the long haul.

4. Everything You Need in One Kit

We designed this kit to streamline the transition from stock VGT to fixed geometry S300 performance, giving you a straightforward setup that gets your truck back on the road fast.

Who Is This Kit For?

• Heavy Towing: For those looking to keep EGTs low and boost consistent under heavy loads.

• Daily Drivers: For those that are tired of replacing failed VGT actuators or dealing with annoying check engine lights.

• Performance Builds: Anyone laying the groundwork for a reliable, high output 6.7 Cummins build.
