** 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.

Comfortable and stylish
Size: 12, Color: Black
I'm very pleased with these shoes. I rarely write reviews, but these are extremely comfortable and stylish. I bought a black pair and a brown paid. Many times I have to get a wide, but the standard size 12 fits me well. Easy to slip into, yet still snug while walking. I feel like the price is reasonable too. Good cushioning, not too thin of a sole.

Good looking shoe.
Size: 9 Wide, Color: Cognac
It's a good looking should which is true to size. Quality is good. However, it is not leather. Inner and outer covering are man made. For me, it's okay. I ordered a 9W which I knew would be no more than a triple E width. I'm actually a quadruple E width so it's taking a little longer to break in. I won't be using these as often as at this stage of my life, I don't have that have functions that require dressier shoes. I'm happy with this purchase, a good value for the price. The slip in feature works well like my Sketcher slip in.
