Here's a link for a thread on Losi's forum discussing it. We had thought that the Mini REvo/Slash diff gears might fit, but you'd have to compare them.  http://forum.losi.com/showthread.php?t=92    I've been in contact with a guy on RCTech that is going to try and have some of the internal gears machined out of metal, so we'll see how that goes... might be a long shot.  If MIP ever made their ball diff out of metal, I think the problem would be solved.

Lee im not sure if these are what you want but Losi makes a Visious diff kit for 60.00 and it comes with those gears and I think you can just buy them seperate ill try to find the numbers for ya ..

here is just the gear and out drive

Try shimming your diffs...
putting a washer between the bearing and the plastic gears so the teeth
are tighter together and mesh better?


Here is a link to spring washers that some people have used with some success in making their
Mini LST diffs a little stronger.

On another Fourm this is called the optimus1T mod for the guy who first tried it...
and shared the info with everyone else.
