I have an 03 3500 SRW 2x4. Is there somewhere to get gears higher than a 373? I have the 410 now and do not tow anything heavy enough to need these. I would like to get 343 or 355 but I was told by a supplier that they are not available. Just want to make sure they are not feeding me a line. Thanks for any help

 

There telling the truth.Some mention that AAM was working on a 3:55.Thats been mentioned a WHILE ago.

 

Try looking for a swap to a older cummins where the 3.55 was stock. swap the whole rear end.

 

That sure would be nice to know. I'm in the same boat. I don't use my 4.10's either and would like something like a 3.55.

 

The OLD ones were/are DANAS.03 up AAM.Apples to Pears.

 

thanks for the help saved me alot of time calling around. I will look at getting the whole setup off an older truck someday. Thanks again

 

If anyone has a 3500 with the Dana 80, I would consider swapping the entire rear assembly from truck to truck. I have 3:54's and need 4:10's for towing.

My e-mail address is available in the public profile if anyone is interested.
