Reading in one of those diesel mags and noticed that chevys (2500) have a 11.5 aam with locker and we (2500) have a 10.5 rear and was wondering if anybody thought about changing one out. I sure would like to have a locker in the rear. Thats one of the biggest things i miss about mine old truck.

 

We do have a 11.5 in the rear.

 

Most also have the factory Limited Slip. Mine works very well. Not as tight as a true locker but close to it.

 

dont the 2500 have a 10.5

 

Nope. They have the 11.5 AAM

 

oh, guess another diesel power mag article is wrong then......whats new... does anybody make a locker for our trucks? i think it was an eaton in my chevy and it worked great.....Dont know if ya can buy one anywhere though

 

well the rear end all depends on what truck you have i have and S.O and i need to check it out but i am sure i have the 10.5

 

oh.didnt know that one........ so when did they start putting 11.5's in all the diesel 2500's

 

Back n 03.Some EARLY 03s were the 10.5 Wasn't used in many 03s either.

 

All the diesels from 04 up have the 11.5 and some have the factory limitedslip. The 03's have mixed 11.5 and 10.5's, the HO's are the ones with the 11.5.
My truck didn't have a limited slip and I installed one because I was tired of waiting for the aftermarket to come out with something. The factory limited slip does work really well in my truck.

 

I agree with Zuki Dan. My factory LS differential (11.5) doesn't seem to work well either. I've read suggestions about applying the brake while trying to get it to lock. That didn't work either. My factory Michelins are lasting great, but DON'T go off road with 'em!

 

does anybody make a locker for these trucks?
