Is the front axle in the 3500 SRW an AAM 9.25 and the axle in the 3500 DRW an AAM 9.75?

 

Both are the same AAM 9.25

 

In your thread you do not state if your truck is a diesel or not. If it is a diesel I would think you would have the same axle that a 2500HD has. In my truck this is the AAM 11.5 rear end the front is an AAM 9.5.
In your sig please fill in what truck you have and the options in this way we can provide the correct information to you.

 

It is a AAM 9.25 The 2500 and 3500 are the same as is the SRW/DRW
