i didnt know there was 2 different versions of the smartdiff. is that what you are asking?

to run in the rc8 the center diff is the same though. in fact, i run a losi center smartdiff in my assoc. rc8t. all you need to do to make this work is disassemble both the smartdiff and your rc8 center diff. then take the outdrives and the bearings from your assoc. center diff and put those on the smart diff and put it back together. the only thing to consider is how large of a spur you want to run. losi and assoc. run different spur sizes and they cant be swapped. shouldnt be too big of deal but just wanted to give you a heads up that your assoc. spur gear will not fit on the losi smartdiff. but your outdrives and bearings will.

so if you are running 46t right now on your rc8 you will probably have to use the 48t losi spur when you switch and just adjust the size of your pinion to get a similar gear ratio to what you had before.
