Available now for the G8 (with a TH400 swap ONLY) is our 3.50″ aluminum shaft. 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 G8 available today. Comes with grade 12.9 hardware with back up lock nuts to ensure no loose bolts. 1 year warranty. You will have to remove the heat shield from above center hanger mount to install a 3.50″ shaft and there is a possibility of clearance issues with aftermarket exhausts. This is a general warning. We have several test shafts out and not one had an issue. I have listed this because not all exhaust systems have been tested. (We also offer a Carbon fiber shaft is made from 3-3/8 and not the 3-3/4 like other manufacturers)
