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 one is the transmission for those who have a slightly modified pickup truck and do some occasional towing.
Rated at 500 Horsepower, it includes our Babymaker 1000 Billet Channel Plate Valve Body, increased clutch count, and a Randy's built twin disc converter.
If you are more of an avid tower/hauler, we would recommend jumping up to our stage two; which gets you into a billet input shaft, triple disc converter, and billet input drum to handle those torquey pulls that come with towing and hauling.
