What kind of shaft do you have? I just spoke to a local shop and I was told that my only option is a steel 2 piece. He said that because of the lenght of the crew cab drive shaft an aluminum one cannot be made.

 

Remember I am AWD. I think it is shorter. The only clues that give it away are huge welds, not stock looking. It is also marked "CSIPDC" or "CISPDC", something like that. I looked it up online and can't find it. It is Alum.

 

Damn I forgot you are AWD. Well looks like I am going with the 2 piece steel!!

 

How long is it and how large a diam. is your shop capable of making?

 

He was saying the longest he would do was 72" plus the yokes. He did not specify the diam. as I assumed it was 5" like the stock drivershaft. Not sure the exact length needed but I believe it is somewhere over 80+".

 

Damn 80"? No wonder there are vibration issues... Either way 2-Piece steel is a proven setup, and will probably be cheaper than aluminum.

 

I just did an actual measurement. The full length of the driveshaft from yoke to yoke is 86".

 

Well the truck is in the shop. It should be done by Saturday. I had a baseline done before the install to see what type of gains I am going to get. Here are my baseline numbers with a k&n intake, flowmaster muffler, and blackbear tune.

 

Looks like yet another stock 6.2 dynos 312rwhp. Our drivetrain's must rob a ton of hp.

 

I wonder how much worse AWD is....
