i have a 2007 hemi qc,is there any way of disabling the electronic anti spin rear diff??

 

"Electronic" LSD? What is that, and why would you want to?

 

I may stand to be corrected, and Parts/Service would know for sure, but I believe the stock LSD in the '07s are not electronic, but still use a friction plate design. Meaning they cannot be "turned off".
I think the only Dodge vehicle set up with such a design is the Power Wagon which has electronic controlled LOCKERS in both the front and rear diffs...

 

That is correct Hammer, as far as the PowerWagon having an E-Locker. The rest are just standard clutch type units.
