This isn't just about big numbers, it’s about smooth, responsive power that you can use both on the street and under load. The compound design gives you fast spool from the smaller charger down low, while the big charger up top keeps pushing strong all the way through the powerband. Whether you’re towing through the mountains or building a street truck with aggressive performance goals, this kit delivers a power curve that feels strong, clean, and usable. Everything is included, turbos, manifold, piping, hardware, so you’re not chasing parts to make it work. The boost is adjustable, and for those pushing beyond 48 PSI, a set of head studs is highly recommended to keep everything locked down. If you want to build your truck around power, control, and reliability, this kit is a game changer.

Precision Matched Compounds For The 5.9L Cummins Platform

The ATS 202-A47-2272 Aurora 4000/7500 Compound Turbo System is designed specifically for 2003–2007 Dodge RAM 2500 and 3500 trucks equipped with the 5.9L Cummins engine. This system features a carefully engineered compound turbo setup, pairing the fast-spooling Aurora 4000 with the high-volume Aurora 7500 for strong, consistent boost across the RPM range. It’s ideal for owners looking to significantly increase airflow and horsepower while maintaining drivability and response. The system is built as a complete bolt-on solution and includes both turbos, a high-flow exhaust manifold, intercooler piping, and all necessary mounting hardware. Boost pressure is adjustable and can be safely tuned as low as 40 PSI, offering flexibility for various builds. However, for boost levels exceeding 48 PSI, ATS strongly recommends the use of head studs to maintain head gasket integrity. With the right tuning and supporting modifications, this kit offers the foundation for big power builds with exceptional turbo efficiency and reliability.
