Apparently that's what I have and the only limited slip available is some factory part that costs $1300... and apparently is a piece of crap and break often.

I thought I had a Dana 70 but a local rear end shop informed me that my vehicle has a Dana 60 super and I'm better off swapping in a completely different rear end. $$$$$

I'm trying to put a limited slip in since in the snow/sand/mildly moist/high humidity environment my Open differential is Junk and I get stuck all the time.

Any rear-end guru's here and can help me figure this out? Not sure that I want to swap out my whole rear-end just to get a limited slip.

This is what I'm working with, 2006 Chevy Express 2500 Duramax.

 

Swap it you *****!!!

 

Installing a factory limited slip(which they claim they replace all the time) = $1300

Swapping the rear end = $1600

...you gonna pay for it Joseph?

 

Found this...

I'm guessing the larger ring and pinion is the issue... :/

 

I just bought another wreck. I'm broke at the moment.

 

I doubt it, did you ask what goes bad on them? Maybe its a bearing issue...

 

I didn't ask them what/why the limited slip breaks, but the problem isn't the rear-end, it's that nobody makes a limited slip for this odd diameter rear-end.

 

Did you ask were they get the up grade rear end from smarty pants???

 

I'm gonna drive down to their shop tomorrow morning and have them visually inspect it. I really have no desire to be swapping rear-ends on this thing if I don't have too. Especially since this thing is considered super beefy.

 

Ask them what fails in these and what rear end they use for an upgrade.
