Ball Diffified

[Balders]

Been talking about this for a couple of weeks with a few people and have finally got around to putting the theory into practise.

What you are looking at here is a Kyosho ZX5 diff in a Durango gearbox. Its taken some light machining but actually fits very well.

To do this you need to machine the out drive bearing stops down by about half a mill so you can fit the Diff in with some play so it can be shimmed correctly and also make the actual drive shaft dog bone sockets 2.1mm instead of the kyosho 1.5mm to take the Durango drive shafts.

You also require 2x LA202 - ZX-5 Diff Input Shaft which needs to have roughly 8mm shaved from it to allow the Durango centre drive shafts to fit, this also enables you to run the Kyosho crown gear because f you ran the Durango metal crown gear it would strip the diff after a lap or so.

Other than that its a very easy mod/change to carry out.



I'm yet to run it but initial feeling is it makes the drive train a lot quieter and free'er as well as a lot lighter.

I'm not the first to try this and I hear there people running this already and would be interested to swap notes with them!
