Super Track Pack 2010 3.06 open diff???

[Suspman]

Hey guys I found diff out of a 2010 RT Challenger with the Super Track Pack which includes the 3.06 diff but its an auto trans car and the diff I'm told by the dealer parts guys is an open diff. However, I am wondering what ring gear size it is what and axle shafts it uses so I can maybe by axles and hubs for an eventual getrag swap. In short is it a 215mm simillar to an 07 era SRT diff, or is it a 226mm or even a 210mm which I think some awd cars came with a 3.06???

It is an open diff. Only the 09+ automatic SRT8 challys have the 3.06 getrag LSD.

I think it would have the same size shafts as the charger srt8s rear end 3.06. Not sure.

[Superman4u]

Pretty sure it takes the smaller axles. Not the bigger 226mm like the GR.

Cool thanks guys. It gets pretty confusing with these swaps-the do it yourself non purchase route that is.

That rear end would be a nice upgrade alone. You feel the gearing more than the LSD anyways.

LSD is more for track use and heating up tires effeciently.

It is nice to have though.

I have the 3.06 getragd lsd and love it.

[Suspman]

Yes that is what I want to say 'I love It'! I can totally feel my Charger spinning a tire here or there, launching is a feathering experience and I hate it. Probably need more tire too though. If I do the Getrag I can keep my 5.7(07) driveshaft too.

Well its going to feel even more "zippy" with the new gearing. Just be careful if on street tires. Get some DRs if you feel it to be too dangerous.

Great mod
