My present original drive shaft is enclosed from the stock 4 speed trans back to the mid support bearing and then is coupled to an open drive shaft back to the differential. How long can an open drive shaft be to extend all the way from the T-5 to the differential? Will I have to have a two piece drive shaft or can I do it direct?
Any help appreciated.

I would think they could modify your existing shaft so that you can retain the two piece driveline. Or they may recommend a one piece? | | | | | Joined: Dec 2001 Posts: 14,522 Moderator: Welcome Centre, Southern Bolters, Legion Hall | | Moderator: Welcome Centre, Southern Bolters, Legion Hall Joined: Dec 2001 Posts: 14,522 | John, since your "just up the road" in Asheville, I suggest you call TOM at Carolina Driveline here in Spartanburg. He has been doing drivelines for years and years. Probably around 30 years. He does it all, Nascar, rock crawlers... you name it, he can do it. Well known in these parts and does absolutely good work. Tom is not only the owner but he WORKS in the shop everyday. Give him a call at 864-597-1916... Jennifer will probably answer the phone. Its OK with me if you tell him Alvin told you to call. He is top notch and not nearly as expensive as the ones over in Greenville,S.C. Here is my new one. Aluminum. http://i140.photobucket.com/albums/r19/LutherParris/52Panel/DriveshaftPanelpics002.jpghttp://i140.photobucket.com/albums/r19/LutherParris/52Panel/DriveshaftPanelpics001.jpg

Diesel trucks with slower turning engines can be longer but best to assume 4000 RPM or more for a gas engine. There will be a limit on the tube size depending on the joint series/size. I'd used 1310 or 1350 Spicer for a longer 1 pc shaft in your truck which is likely larger than it was built with.
Always a good idea to talk to the local driveline shop before jumping in as there is a lot of bad advice out there. Use a tube /yoke [censored]'y as the starting point so there will only be one weld involved. Some guys will try to bill you for two welds. I did this kind of work for many years and owned a driveline shop so I do have some degree of knowledge of this. | | |
