MITSUBISHI 91-93 3000GT VR-4 (5-Speed) 950HP Heavy Duty Aluminum Driveshaft

This is our 950HP 3.5″ Heavy Duty aluminum drive shafts for the 3000GT VR-4 and Stealth VR-4. 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 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.
