Driveshaft Shop 91-93 3000GT VR-4 5-SPEED 650HP 3" Aluminum Driveshaft This is the Aluminum driveshaft for the 3000GT/Stealth VR-4 5-speed.
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" 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 24lbs 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 is rated for 650HP and 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.
