Available now for the 2012+ Camaro ZL1 is our 4 inch aluminum shaft with CV . We have 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 Camaro available today. The shaft will come with our signature billet plates for each end so you don't have to go into the rear taking a chance on upsetting the crush collar. Our 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 closley at the CV end, it's not all steel). The shaft only weighs 17lbs 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.
You will have to remove the heat shield from above center hanger mount to install a 4" shaft there is a possibility of clearance issues with aftermarket exhaust. This is a general warning. We have 9 test shafts out and not one had an issue. I have listed this because not all exhaust systems have been tested.
