ATS Diesel Performance
Share
For over 30 years. ATS Diesel is a Colorado-based company that manufactures a number of different products for light duty diesel vehicles.
whether you rely on your truck for work or for play, ATS Diesel has the parts for your diesel engine and transmission that will ensure years of performance and confidence in your truck. We also perform regular repair work and maintenance for our customers. ATS is unique in the fact that we actually produce our own line of parts in-house rather than just being a reseller of parts or having components made for us.

Test it. Dyno it. Then put it to work. ⚙️
At ATS, we use Hydra-Test machines to test solenoids and complete valve bodies under controlled hydraulic conditions—allowing us to command solenoids, cycle spool valves, monitor pressure, and identify internal leaks or pressure loss.
Instead of guessing, we can see exactly how the valve body is responding and verify proper operation before it ever makes it into a transmission.
Tested in-house. Verified by ATS. 🇺🇸
The NEW ATS Five Star ZF 8AP Torque Converter for the 2025+ 6.7L Cummins is almost here. 🔥
The new 8AP 8-speed is an entirely new transmission platform for Ram HD trucks, and ATS is already pushing the platform forward.
More holding power. More durability.
Made in Avarda, CO 🇺🇸
Next up in the VFR Series — CARB certifications.
Getting a CARB EO isn’t easy. The testing is strict, expensive and time-consuming — and every year range and application matters.
More VFR turbos are receiving CARB EO certifications, with most of the line now certified 🐌🇺🇸

Before ➡️ After. 🇺🇸
From a raw sheet of steel to a precision-machined part, it happens right here in our machine shop in Arvada, Colorado.
American manufacturing. ATS quality. Made in-house. 🇺🇸🦅
ATS VFR vs. stock — what’s the difference? 🐌
It comes down to efficiency. A lighter 8x8 splitter compressor wheel means quicker response, less heat, denser air and a more efficient burn. The result? Quicker spool-up, better efficiency and more power.
Racing-derived technology engineered into a factory-style drop-in turbo for your daily-driven Cummins. 🇺🇸
2025+ Ram VFR 3000 — Part 2. 👀🐌
The new reverse-rotation setup meant everything had to be re-engineered, but it also gave us the opportunity to address the reliability issues we’re already seeing with the factory turbo.
Thrust, bearings, sealing — the small details matter when durability is the goal.
The 2025+ VFR 3000 is coming. 🇺🇸
Ram 2025+ VFR Turbo - The secret’s out. 👀🐌
The Aurora VFR 3000 for the 2025+ Ram Cummins is right around the corner. With the new reverse-rotation turbo setup, we had to go back to the drawing board and engineer an entirely new VFR platform for the latest generation trucks.
Coming soon. 🇺🇸
You asked for it — the Aurora CVNT Compound Turbo Kit for the 5.9L Cummins is coming. 🐌🐌
Start with the quick-spooling CVNT and when you’re ready for more power, step up to the compound setup with the Aurora 6000. Quick spool, fast response and a whole lot more air density.
Right around the corner. 🇺🇸
Next up in the VFR Series — the future of diesel emissions.
Emissions requirements continue to shape the diesel industry. We break down where things are headed, how regulations continue to evolve, and what that could mean for the future of diesel performance.
Where do you think the industry goes from here?
Next up in the VFR Series — efficiency.
Small changes in the turbine and compressor sections can make a BIG difference. Capturing more exhaust energy, generating less heat and packing more dense air into the engine means more power and less black smoke.
Less heat. More density. More power. 🐌💨
