Product Description
MITSUBISHI 94-99 3000GT VR-4 (6-Speed) 650HP Aluminum Driveshaft
This is the Aluminum driveshaft for the 3000GT / Stealth VR-4 6-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 3.5″ in diameter. 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 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.
Driveshaft Shop Driveshafts are built to handle not only the power of drag and drift cars but also add to the efficiency of these types of racing. Aluminum has been used in drive shafts for years but most people think its just because they are lighter - Were you aware they are more torsional?
By being able to twist more than a steel shaft it will not only make the ride smoother but it will also take some of the harmful shock factor out of the drive train helping to keep up the RPM. This will also help to save most output shafts and other related drive train parts down the line. The aluminum shaft also has a higher resonant frequency than steel (a steel shaft will act as a amplifier of vibration). An aluminum shaft will deaden the vibration due to its characteristics.
