SCROLL DOWN FOR BUILD SPECS

Since 2007, the 68RFE has been the standard option transmission for the Dodge/Ram Trucks with the 6.7 Cummins Turbo Diesel. In that time, there have been many flaws with it that Chrysler has not addressed. Rest assured, your stock 68RFE can be built to eliminate worry - that does not require a need to swap to a different style transmission.

We have committed ourselves to building the highest-quality transmission for your pickup; tailored to what you do.

Our stage four is the transmission for those who are focused on street performance. You’ll have peace of mind with the stage four; which includes our ‘Babymaker’ series billet valve body, increased clutch capacities throughout, billet internals, billet input shaft, and a triple disc torque converter or optional XHD Quad Disc Converter- just to name a few things.

With its 1000+ Horsepower rating, it is ready to handle the power made by your truck and the antics you may want to do with it.
