DSS 3.8” carbon fiber driveshaft is now available now for the 2015-2017 S550 Mustang with a T56 Magnum XL swap. This shaft comes with a 300m stub system mounted into a billet aluminum plate to ensure not only strength but lighter weight than the normal way of doing this type of end (look closely at the CV end, it's not all steel). The shaft only weighs 20 lbs and comes with special grade 12.9 uber strength hardware with back up lock nuts to ensure no loose bolts. We have been using this billet aluminum style plate for over 10 years on thousands of 1000+Hp Supras, BMWs and many more without any bolt issues. 1 year warranty.
