This is the new DSS Coupler Eliminator Carbon Fiber driveshaft. This shaft will mount directly to the metal flanges on the vehicle, without the rubber guibo couplers, which are prone to deformation and eventually failure in high HP applications. We have redesigned these shafts to be a direct fit with no drilling of your stock flanges or other modifications required, and we also include new grade 12.9 hardware to mount it. These driveshafts feature our own CNC billet aluminum ends that are precision machined a second time, after the driveshaft is fully assembled, to ensure perfect centerline. We then high speed balance the shaft to eliminate any possibility of vibration. This specially wound carbon fiber tubing was originally designed for a 4500lb vehicle, calculating a traditional first gear torque multiplier of the transmission behind the engine, which will far exceed that of any torque tube application. The shaft is approximately 6.7 lbs and will withstand well over 900HP.
