Available now for the 2018-20 Mustang GT 6-speed is DSS' 4" aluminum
shaft with CV. DSS has done extensive testing with stock rears and with
our 9" kit and believe this to the the most cost-effective trouble-free
driveshaft for the Mustang available today. DSS 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 35lbs 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.
