I've had several done from Inland Empire. Always excellent quality, and always on time (about three days from ordering to delivery for me). The last couple were 4" aluminum, have done 3.5" also in the past.

Dynotech from Troy Michigan did my last one. Excellent quality and very quick. Kyle from DSE recommended them :thumbsup:
3 1/2" Aluminum

Accu-bond aluminum drive shaft from Mark Williams. Great service and turn around time.

My 3" aluminum DS is rated for a critical speed of 9374 rpm and a torsional yield of 3633.75 pound-feet.

And yes I stayed at a Holiday Inn Express last night.

I was looking at that Raj. What exactly is accu-bond?

Yeah, but did you eat at Denny's? :D

PST carbon is what im purchasing.

Hey Ron -- from what I was told is that the aluminum matrix (Duralcan MMC aluminum) used in the Accu-bond drive shafts is not "weld friendly" but stronger than 6061. The guys at the shop swear by the Mark Williams stuff. Here is a quote from their site:

Accu-Bond driveshafts utilize the Patented (7,485,045), end fitting bonding process that much stronger than conventional welded shafts. The end fitting are produced from 7075 forgings 50% greater strength that conventional welded fittings. The result is a stronger and more accurate running shaft at a reduced cost compared to the Aluminum and Carbon Fiber shafts.

Just technical enough to make me try it...:cool:

I had Inland Empire build my drive shaft. It took them two tries and they still didn't get it right so I had a North County San Diego shop (Oceanside Driveline) fix it due to time constraints. I seem to recall this happening to Rupp once and they fixed it on their dollar, no hassles or anything. If I was local to them I wouldn't hesitate to have them build another drive shaft for me in the future. I want to think I just had bad luck.

How much is that going to run?
