Is the ATLAS 2 speed transfer case configuration same for JK manual transmission and 545RFE, in terms of input and output shafts, splines etc

I will be doing a Hemi V8 conversion in the near future but was just wondering if I can upgrade the stock transfer case now or do I have to wait?

Bec so far i have seen hemi V8 conversions running stock JK transfer cases?

I have a manual 6 speed jk and will be doing auto 545rfe trany

 

I am still waiting on mine to get here. I just ordered one and they let me choose the output flanges I wanted. I am not sure about the input flange since i still have the v6 but i will let you know when i get it.

 

We did a very early Hemi conversion and backed up the 545RFE with a 2 speed Atlas. At that time we found that the trans could have a couple of different patterns. I would check with AA. They will have much better, current info.

You'll love the Atlas. Once you have a twin stick you'll NEVER go back.
