** 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.

Great for bookshelves!
Size: 9.25 INCH
Heavy duty and super sturdy. The brackets feel solid and well made, and once installed they hold shelves very securely. Great quality and exactly what I was looking for for an industrial-style shelf setup.

Great feel and quality, will buy again
Size: 5.5 INCH
These are gorgeous! The thick, heavy look and feel that I was hoping for, great screws to match (we used different anchors, since the provided anchors are not the strongest style). Similar ones at the local big-name hardware store are at least three times the price and are no better quality. I would (and will) definitely buy these again for more projects. Originally bought the six of these even though I only needed two because the price was still the best I could find, and ended up using all six almost immediately. They look so good, I found more projects for them!
