ATS Diesel 03-07 Dodge Cummins 5.9L Aurora 4000/7500 Compound Turbo Kit

The Aurora 4000/7500 compound turbo system from ATS Diesel is built around a unique 4000 series high-pressure turbocharger paired with a 7500 series low-pressure turbocharger. This setup is designed to work together to provide a significant boost in airflow and power for your 2003-2007 Dodge Cummins 5.9L engine. Compound turbocharging helps to spool up the larger turbocharger more quickly, reducing lag and improving overall engine response across a wider RPM range compared to a single turbo setup.

ATS Diesel has engineered this kit to be a comprehensive solution for Cummins owners looking to upgrade their forced induction system. The kit includes all the necessary components for installation, such as high-quality piping, robust mounting hardware, and custom-tuned control systems to ensure optimal performance and reliability. The materials used in the construction are chosen for their durability and ability to withstand the high temperatures and pressures associated with boosted diesel engines. This means you get a well-built system that's ready for demanding use.

When installing this compound turbo kit, it's important to ensure your fuel system and exhaust are also capable of handling the increased airflow and power. Many owners find that upgrading these components in conjunction with the turbo kit yields the best results. This system is not CARB approved and cannot be shipped to California due to emissions regulations.
