Includes 360° Thrust Bearing in Every DPS Turbo – 60% More Load Capacity
Full Compound Kit – Includes Everything for Installation
The DPS 6.7L Cummins Compound Turbo Kit offers near-stock spool-up with significantly increased airflow. Designed for towing, racing, sled pulling, or high-performance street driving. Customers regularly report a 300–500°F drop in EGTs compared to single turbo setups.
Boost pressure typically exceeds drive pressure — unlike single turbos, which often suffer from high drive-to-boost ratios. This compound setup improves throttle response and increases horsepower across the full RPM range.
Optimized for builds between 350 HP and 800+ HP. Designed with CAD/CAM and tested using CFD (Computational Fluid Dynamics) software for maximum airflow, durability, and perfect fitment.

Hello,I do not normally comment on my truck part purchases, but I felt the quality of your kit was worth taking the time for. I recently purchased one of your stocker / S475 kits for my 06 ram. I have to say I am very impressed with the quality and packaging you guys do. This is my first compound turbo set up. I looked at many kits before purchasing yours. I looked at cheaper and more expensive. I had nearly talked myself into buying a cheaper kit. After receiving your kit I was immediately satisfied with spending the extra money on it. I opened the kit and was very impressed with the packaging alone. I thought to myself, if it performs half as well as it is packaged, I was going to be very happy. I had one issue after installation, but it turned out to be my fault for assuming. I assumed the tube from the output of the S475 to the input of my stock turbo was molded to the connector that uses V band clamp onto the S475. I had one extra clamp once installed and I thought it was odd, however I took the truck for a test ride and was very impressed with the faster spool up but the system got very loud and not as much boost as I had anticipated. I found out very quickly where the extra clamp went. After that mistake was remedied, the system is performing flawlessly. I am very satisfied with this kit. I look forward to putting it to the test towing in the Colorado mountains. I will be purchasing your intake for this same truck as well as probably upgrading my stock turbo to one of your new ball bearing turbos in the near future. I will not hesitate to recommend you guys to anyone who asks.
Best thing I could have done sooner was do compounds for my 6.7Cummins! Stock fuel with some items not on the truck and it tows awesome. Steep grades and EGTs issues are a thing of the past! Great kit
