Mustang GT Automatic DSS 1-Piece Aluminum Driveshaft FDSH44-A
the 2015 Mustang now has an independent rear suspension (IRS) and the
driveshaft is a little different than the S197 cars. Although the
factory one is still a 2 piece shaft, they are different in
configuration. Automatic uses a 4-bolt flange on the back of the trans.
What's great about this car being IRS is that there are no
issues with angles, adjustable arms or ride height issues that can
affect the drivetrain. The Carbon fiber driveshaft will give more of a
torsional twist but with out the harmful reverse snap given from
steel.. This will not only reduce harmonics but also help with 60ft
times. And the ends are either Billet or Forged, we never use
inexpensive cast parts in our shafts.
