The ATS Billet
input shaft is the back bone of your Ford Powerstrokes 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 input shaft has 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.
The theory behind billet shafts is not quite what you may have in mind.
The key to success is not to make the shaft "stronger" necessarily,
but give it the ability to absorb more torsional load. The way we do
this, is by using billet shafts, they have the ability to rotate
further with out breaking. This is going to give the transmission more
"give" and allow it to transmit more torque and more load with out
Along those lines, breaking an input shaft can be catastrophic to your
transmission. Sometime when the shaft breaks, your truck will simply
stop moving and it needs a new input shaft. Other times, when that
shaft breaks, it can take out your torque converter, front pump, and
front seal as well. Obviously this is going to be a very costly repair.
Then add on top of that labor time, fluids, new gaskets and seals,
and you can quickly see how this can add to the cost fairly quickly.
It is simply good insurance to hold reliable power in your transmission, to add at minimum a billet input shaft.
