24V Multi Layer Manifold Gasket Kit with T3 Gasket for 1998-2018 1045986
(3)
The DPS Dodge Cummins Compound Kit pairs the high-performance S480 turbo (now updated to our new S481) with an S300 high-pressure turbo. This twin turbo setup is engineered for serious performance, towing, and thermal control, delivering up to 1100 HP and lowering EGTs by 250–450°F.
Start by determining your desired horsepower. Our compound systems boost power by 25–30%. Choose the appropriate stage from the list above and select it from the drop-down menu during purchase.
Our dual-stage compressors work in their most efficient ranges, delivering cooler air—over 100°F cooler per PSI than single turbos. The boost and exhaust drive pressures approach a 1:1 ratio, maximizing combustion and reducing heat. More oxygen means more power and cleaner burn, like a jet engine. These features result in faster spool-up and massive gains in drivability and reliability.
Our kits are capable of producing over 55 psi of boost, but are fully adjustable based on your setup.
We also offer Fummins and Chummins kits tailored for Ford Cummins conversions.
Fits all Dodge Ram Cummins model years from 1988 to 2018, including: 1988–1993 12V, 1994–1998.5 12V, 1998.5–2002 24V, 2003–2007 5.9L CR, 2007.5–2018 6.7L CR.
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
Hello Power Geniuses, Just dropping a line to say great!! job.I purchased a compound kit for my 04 Dodge in July of 2014. Fantastic power & RELIABILITY !30k miles of driving & towing with a big smile on my face.Thank you for your knowledge & great products!
I put one of these kits on my 04 Cummins probably 5 or 6 years ago. I have nothing but good to say about it. It has towed loads that do not belong behind a pickup, on a regular basis and has never once disappointed.....
