All too often, we see truck owners trying to take the "cheap" route when doing tranmission builds, which ends up costing them thousands more in the long run. One example of this is adding a high quality, bullet proof torque converter, billet input/output, but not changing the intermediate shaft. The ATS Billet intermediate shaft is part of the back bone of your Ram's transmission. It is the first hard part to bring power into the transmission and transmit that power to the wheels. With no dampening or power loss other than the torque converter, the shafts in your transmission have a lot to handle. Now add power, weight from a trailer, bigger tires (and is some cases all these things together) and you will be well beyond what that factory shaft was designed for.
