hey guys my brother snapped his rear drive shaft toting around 32000 lbs with his 6.4, after a long search for something worthwhile he finally found CCI Driveline out of Michigan. Ordered an upgraded version of there Super Duty drive shaft and loves it. Its a one piece monster 5" aluminum tube with heavy spicer joints on each end and it looks great. he said the customer service was great and they made sure he got fixed up with the right stuff. here is a link to their website i would recommend them 100 percent.Quality Custom Drive Shaft and Drivelines - CCIDriveline.com

 

Looks like it would be $10-$20 cheaper than the OEM for a '08 CrewCab 4WD truck. It's hard to tell for sure, but do the U-joints have threaded ports for grease zerts?

 

They are nice. My 2011 F250 came from the factory with the Aluminum drive shaft.

 

How's the aluminum D/S holding up? Is your brother still happy with it?
