Starting a group buy on 3.5 inch aluminum driveshafts. We have one for 5 speeds and also one for 6 speeds.
These are our 950HP rated 3.5" Heavy Duty aluminum drive shafts for the 3000GT VR-4 and Stealth RT-TT not the 3 inch like are sold elsewhere. 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. Thats a 40% reduction in rotating mass plus you are getting rid of a carrier bearing!
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 well under the car and also the operating angles would not allow for a 1-piece shaft to work properly without vibrations. 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.
These driveshafts are dynamically balanced at 9000 rpms and come with a 1 year warranty.
These are going to retail for 850 plus shipping but if we can get 5 people to sign up and pay for either kind (5 or 6 speed) we will offer them for 750+ actual shipping. If we get 10 people to sign up and pay we will do them for 700 + actual shipping.
Put your name, which kind you want (5 speed or 6 speed) after your name, and zip code.
