ATS Diesel 03-07 Dodge Cummins 5.9L Aurora 3000/5000 Compound Turbo Kit

If you're looking to significantly increase the power and towing capability of your 2003-2007 Dodge Cummins 5.9L, a compound turbo kit is a serious upgrade. This ATS Diesel Aurora 3000/5000 kit is designed to provide a dramatic improvement in airflow and boost pressure, especially at higher RPMs, giving you more usable power throughout the entire range. It's a complex system that works by using a smaller, faster-spooling turbo (the Aurora 3000) to feed air into a larger, high-flow turbo (the Aurora 5000), allowing for both quick throttle response and massive top-end power.

This kit is a well-built system that uses robust components to handle the increased demands. The Aurora 3000 is known for its quick spool-up, reducing lag and getting you into the powerband faster. The larger Aurora 5000 then takes over to provide the high-volume airflow needed for significant horsepower gains. ATS Diesel has engineered this setup to work together seamlessly, aiming for improved performance without sacrificing too much low-end drivability. Installation is involved, as with any compound turbo setup, and will require careful routing of plumbing and exhaust components.

When considering a compound turbo system like this, it's important to be aware of the overall changes to your truck's performance. You'll likely see a substantial increase in horsepower and torque, which can greatly enhance towing and hauling. However, this level of modification may also require supporting modifications to your fuel system and drivetrain to handle the extra power safely and reliably. Please note that this kit is not CARB approved and cannot be shipped to California. It also falls under California's Prop 65 warning requirements.
