All the 08 mega's and QC's have 1 piece now.

So there is mixxed opinions on aluminum,what about a custom made steel one?Is the length just too long to take the extreme torque of a heavily modded CR?

Should be the same, it's the same frame between QC long beds and Mega Cab short beds.

the aluminum might be fine for normal use im just saying ive seen a few break in half pulling. and the ujoints are bigger ive layed the 08shaft next to a 06.

I got a one piece aluminum shaft from an 08 6.7 and 68rfe. I measured it and it is one inch shorter than my steel 2 piece. I assume the 68rfe trans is longer than my 47re. I also got the front shaft, I am going to measure it compared to mine 2day and see if it is 1" longer. Before I pull mine out does anyone know for sure the splines are the same for the 2 different transmissions? I measured the outside diameter of the yoke and they are the same.

they are the same t case,not sure if youre doing this on a 2wd.

I don't get you guys with the trashed 2 piece drive shafts...

I spank my truck all the time...and my carrier bearing is fine after 160k. I changed my Original U-Joints at 100k when I broke one lobe of the rear lower joint that I attribute it to being hot/dry.

Maybe it is a result of good traction bars?

How do you know when your u joints are going out? I dont feel any play in them, but i get a little pop in the front end every now and then while accelerating from a stop.

I'd really like to do this soon. Any of you guys that have done it have a part# for the 08 shaft? I have a quadcab lonngbed auto. I assume the inch shorter length isn't enough to matter? I have an add-a-leaf in the rear as well but I doubt that it makes enough difference?

I completely ripped my carrier bearing off the truck during a sled pull. Before I do it again I will be switching to a 1 piece. Imo thats the weak link.

I just bought a new carrier bearing and it's much stronger than the stock one. Looks totally different.

The PN I used is 5212320AB.

But like said.....I'm not comfortable with a shorter shaft....meaning loosing 1 1/4" on the output of the Transfer Case out put shaft. I put the two piece back on.

Were did you get it from?? you have a p/n and a price?

I resurrected another thread on this subject and someone said the reveal on the shaft where it goes into the tail section is the same. A straight shaft with no bend I would think would not need to be as long as a two-piece that has a bend in it. The shortest distance between two points is a straight line kind of theory but i'm no expert. I have found enough positive experiences on the forums that I just finished ordering one. Hopefully I can add my own positive experience soon. I avoid my dealer if at all possible so I got one from dodgeparts.com was just under $500 with shipping. Will keep y'all posted. Thanks PowerWagon for the PN - that's the same one I found on the other thread so at least I know it should be right.
