Does dodge and chevy have the same rearend in both diesel versions? I have read on here and i noticed alot of people thought both ways and nobody said for sure.

 

If I'm not mistaken, they are both AAM 11.5s but the internals are a little bit different.

 

both AAM axles, a joint venture between DC and GM.

 

New Venture, now New Process, was a joint venture. AAM was a captive GM supplier, now a separate public company. Wouldn't be surprising if the 10.5 and 11.5 14 bolts look the same btwn GM and Chrysler but have minor differences; not sure how to find out for sure without dissecting a couple or good luck getting AAM to divulge that info.

 

I was wondering if the locker in a chevy would fit a dodge?

 

i think it will!

 

Why would you want to use a GM GovBomb in your Dodge? Most GM guys want to get rid of those.

 

i had one for 100k and it worked great and my fathernlaw has one at 257k and it works great too.. Dont matter anyway i lost the bid on ebay, it was 58 bucks or something and i was outa town

 

parts interchange , ie : dodge into chev and vice versa.. but when you compare them side by side you'd never want to.... lol.. ill try to take a few pics while at work as a comparison...

 

From what I've been told, the differences between the Dodge AAM 11.50 and the GM AAM 11.50 is the size of the brake rotors and the limited slip diff. It used to be a popular mod to put the limited slip diff from the GM rearend(which is NOT a GovBomb, BTW) into the Dodge rearend. The limited slip diff in the GM AAM 11.50 is a Torsen type whereas the Dodge version is a clutch pack type. I hope this helps you out a bit.

You are mistaken.

The Dodge is the one with the torsen style "Trac-Rite GT" diff. http://www.aam.com/index.php?s=49&item=99

The GM G80 is indeed the dreaded Gov-Bomb....although the 11.5 may be better the the earlier design. My scrap barrel is full broken ones, if that's any indicator of thier durability.

I like to see a pic

I've replaced several from the 8.5 rear end (which is undersized to begin with) but I've never seen a broken one from a 9.5, 10.5 or 11.5

I'm not saying the Eaton is the strongest unit but it flat works as designed.

The TracRite certainly has it's own limitations.

 

gm has small brakes, thin axle tubes, weak carrier etc....
i forgot my camera.... but fyi on open carriers atleast the gm cros pin in mayby 1" vs the dodge@ almost 2"....

and like tony said... the gm got the g80 gov bomb... chrysler got the torsen type.

pleas dont make me spend all night finding the old pics catalogs data sheets etc here,,,,

next thing you know we'll have jt on here claiming he has 3.42's on the shelf for the 11.5......

 

Oh man, I wanna see pics, that would be great, but don't kill yourself.

 

You're right. I was mistaken. Thanks for the clarification.
