Our new torque tube driveshaft is made from 3.5" x.125" wall 6061-T6 aluminum and uses our own custom machined ends that will eliminate the rubber couplers. This will ensure that the shaft will not distort or break like the factory units, and you will eliminate distorted and broken couplers in high HP applications. The factory shaft is made from a smaller tube (there are 2 different types) and will flex and actually bend during hard acceleration, causing the rubber drives to wear out prematurely. Available for C5, C6 and C7 applications, and can also be made to custom lengths. Rated to 1000HP+ with a 1-year warranty.
