93-95 RX-7 Twin Turbo 3″ Aluminum shaft. The 1-piece driveshaft that we offer for the RX-7 is lighter than the stock driveshaft, but is also considerably more torsional. A steel shaft can torsional twist 5-7 degrees, where an aluminum shaft can twist as much as 15-20 degrees. This means a smoother ride and better response. Comes completely assembled, balanced and ready to install.
