Hay Gallagher!!
I don’t use the T-Bones so I cant answer your first question..
But I do use the stock Traxxas 3905 E Maxx drive lines in my GR3 and my G3.0, both of my trucks have a Nue motors. GR3 has a fast lane single speed and a 3905 E Maxx trans in my G3.0, with RCM buggy 1/8 diffs in both of them, so yes they are being tested..
So far no issue at all..
Here is picture of them installed in GR3.
And their Cheep to use!!!
just buy two rear 3905 drive lines and mod / cut them to proper length, Mike even sells the 1/8 diff adapters for almost noting,

the total investment should put you back $35
Hope that helps..
Have a great one
