I am glad I used the search button. I was thinking on going up to 4.10 from my stock 3.21 on my 3.7. My drive shaft is a 2 piece and from the rust on it, I can only "make an *** out of you and me" that its steel. But it is for the 3.7, and with the 3.21 I can feel the vibration at 5000 rpms. I never knew that it was from my shaft. Do you guys think that my drive shaft will handle a 4.10? Thanks all and Hank, feel free to chime in.

 

I know the Power Wagon's have a specifically designed driveshaft to deal with the forces imposed by the 4.56 gears. And BTW, all Power Wagons have 4.56 gears. I have no idea what the differences are compared to the stock 2500, but I know they are different.

It is the many details like this that make me glad I bought a Power Wagon. All the "mods"are done right - straight from the factory.

 

I have an aluminum shaft, '07 2wd V6.

 

my buddy has an 03 1500 chevy his did the same thing at 35000 miles
and it was an aluminum shaft aswell
he told me to check mine I said its a dodge why worry about it mine is steellol

 

Is it a 2 piece?

 

Nope

 

Damn. I have a 2 piece. I read here that the 2 piece is better, but how much better to go up to 4.10 on a 3.7 engine?

 

I would not go to 4.10 on the 3.7L. My '93 Chevy diesel with 4L80E tranny had 4.10's and I hated it. It was strong off the line but horrible on the hiway.

 

When you say horrible, what is exaclty that you mean? the rpms to high? engine noise? . . . what do you mean I'm funny? I'm funny how?, how am I funny? do I look like a clown? do I amuse you?







. . . sorry side tracked there for a bit.

I did the rpm calculator and with my overdrive 6-gear on HWY 70 speed, I was about 2350.

 

My 06 2wd hemi ram has a thin coat ofrust on my drive shaft. My guess is that it is steel, lol.
