A DPS compound setup pairs a smaller high-pressure turbo with a larger low-pressure turbo. The small turbo lights first for quick response. The large turbo supplies airflow as load rises. The result is smooth power across the entire RPM range with better temperature control on long grades and under heavy throttle.
You’ll be impressed by your diesel truck’s response with a DPS Compound Turbo kit. If you want a dependable setup that controls heat and puts power to the ground, compounds are the proven path.
Kits are available for popular 5.9L and 6.7L Cummins applications. Verify year-specific parts, flange styles, intercooler piping, downpipe, and oil feed/return requirements on each product page. Experienced DIYers can install with the right tools and time; professional installation is recommended if you are new to compound plumbing.

A compound turbo kit uses two turbochargers working together, typically a smaller high-pressure turbo and a larger low-pressure turbo. The smaller turbo provides quick spool and low-RPM response, while the larger turbo supports high airflow and boost at higher RPMs. This setup delivers faster spool, higher horsepower potential, and lower exhaust drive pressure compared to a single turbo system.
Compound turbo setups are designed for serious diesel performance. Benefits include quicker spool-up, improved throttle response, higher boost capability, reduced exhaust gas temperatures, and better overall efficiency under load. They are ideal for towing, racing, and high-horsepower diesel builds where a single turbo becomes a restriction.
Yes, when properly sized and tuned, compound turbo kits can work very well for towing and street-driven diesel trucks. The small turbo improves low-RPM response and drivability, while the larger turbo handles airflow under load. Many compound systems are specifically designed to balance daily driving manners with heavy towing and performance use.
