Wehrli Custom Fab Twin Turbo Kit, Dodge (2007.5-09) 5.9L Cummins (S400/Stock)

Compound Turbo Kits (also known as Twin Turbo Kits) for the 5.9 Cummins have become one of the most popular upgrades for daily drivers and towing rigs. The s300/S400 Kit replaces the factory Variable Vane Turbo charger with a fixed vane type S300 Turbo. Properly spec’d setups can operate very well at lower horsepower ratings and still tow extreme weights. But you also have the option to push the horsepower level to over 1000RWHP. (With proper supporting modifications) Kits are available without turbo chargers but we will need to know what you are planning to use, and in some cases, may need your turbos sent in for the build process. Every WCFab Turbo kit is hand build in house by our experienced fabricators and welders. Every component is built and test fit on our jigs to ensure proper fitment. All tubing is TIG welded and the mating flanges are CNC machined with O-ring seals where necessary for a boost-leak free setup. We stand behind our fabricated components and workmanship for the life that you own the product. The Compound Turbo Kit comes with all the necessary components to install, with several upgrades and turbo options available. Powder coating is included in the price. Certain upgrades are necessary for optimum performance and drivability. (I.E- Tuning and FASS Lift Pump)
