    Center Diff - plastic housing?

    From pictures, the center diff housing appears to be plastic. it also looks like a normal front or rear diff case on the xmaxx. My question is this: can i upgrade to the xmaxx 8s center diff housing and internal gears or not?

    Diff case fits, so do the spider gears. Now lets see if it will fit inside....
