Step Into Serious Power With A Setup Built To Dominate

If you are chasing big power out of your 2019-2024 RAM 6.7L Cummins, this ATS Aurora 4000 VFR 6000 compound system is built to deliver exactly that without holding anything back. From the moment you get into the throttle, the truck feels alive with a strong and immediate response that quickly builds into a hard pulling surge. The larger 64mm VFR turbo brings more airflow to the table right from the start, giving you a noticeable jump in power compared to smaller setups. As boost climbs, the Aurora 6000 takes over and keeps the truck pulling hard through the entire RPM range, making it ideal for aggressive towing or high performance driving. Additionally, the increased airflow helps keep temperatures under control, which is critical when you are pushing this level of power. This system is built for drivers who are not just looking for an upgrade, but a complete transformation in how their truck performs. Once everything is dialed in with proper tuning, the difference is something you feel every time you put your foot down.

Engineered Compound Turbo System For High Horsepower Applications

This setup is designed as a true high performance compound system, pairing a 64mm Aurora 4000 VFR high pressure turbo with a 75mm Aurora 6000 low pressure unit to support up to 900 horsepower and 1750 lb-ft of torque. The compound configuration allows each turbo to operate efficiently within its range, improving airflow delivery while reducing strain compared to a single turbo pushing the same output. Furthermore, the system includes a ceramic coated Pulse Flow exhaust manifold that helps retain heat energy and improve turbine efficiency, which plays a key role in maintaining consistent boost. An updated electronic actuator on the primary turbo ensures precise control and proper integration with your tuned setup. The kit also includes all necessary hardware, plumbing, and connections, allowing for a more straightforward installation without sourcing additional components. Additionally, this version is intended for custom tuned applications, meaning proper calibration is required to fully utilize the increased airflow and prevent drivability issues. Altogether, this is a well balanced system designed to deliver maximum performance while maintaining reliability under demanding conditions.
