** DSS ITEMS ARE NOT IN STOCK AT SPEEDFACTORY RACING, MOST ITEMS ARE MADE TO ORDER 4-6 WEEKS FROM ORDER DATE **

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)

Special Note: Rear Subframe/Cradle Lock-out kit must be installed on the vehicle prior to installing a Driveshaft Shop 1-Piece Driveshaft. Any damage to the driveshaft (or any subsequent damage) caused by failing to properly reinforce the rear cradle and limit movement will void any and all warranty provided by The Driveshaft Shop.

Easy to assemble
Color: Grey, Color: Grey
Staying in a flex bedroom for few nights and got it to get some more coverage, super fast and easy to assemble, no tools or muscles needed, just pay attention to the ends of the bars : 2 vertical bottoms were marked, 4 horizontal ends are different to be easily attached to vertical frame; very lightweight but sturdy, nice shade of gray, the room still feels bright snd spacious; matches the description

Nice.
Size: Medium, Color: Prime Pink/White Assorted
These were great quality and perfect fit. They held up. Under Armour seems to make the better quality socks than others.
