Driveshaft Shop 950HP 3.5" Aluminum Heavy-Duty DriveshaftThese are our 950HP 3.5" Heavy Duty aluminum drive shafts for the
Eclipse and Talon. This shaft is designed to replace the first 2 shafts
of the factory 3-piece system. They are made from 6061-T6 aluminum and
3.5" in diameter, it also includes a custom 7075-T6 aluminum plate to
convert the CV back to a u-joint style end and bolt to the factory rear
shaft section. The first 2 pieces of the stock shaft is 22lbs and our
single is only 12lbs. The aluminum shaft is also more torsional than the
shorter steel shaft and will help save the rest of the drivetrain from
the harmful shock factor of launching the vehicle at the track. We were
going to try to make a single shaft but due to Critical speed
limitations it would need to be 4" in diameter and would not fit under
the car and also the operating angles would not allow for a 1-piece
shaft to work. The front angle was 2 degrees and the back was 7 degrees
(not good), the problem is the rear joint would move more than 2 times
as much as the front and cause a very nasty vibration. The AE-7 manual
of Automotive engineers doesn't recommend any driveshaft to have more
than a 1 degree difference from one operating angle to the other (this
would be a 5 degree spread). Some of the carbon fiber shaft company
makes this shaft but the angle problem still remains and in our opinion
will cause the fiber to tear over time and fail. This shaft comes
complete with a conversion plate for the CV end and all hardware to make
this a job that can be done in the garage. This Heavy Duty shaft is
rated for 950HP.
