Gear Diff for TRF201

[Origineelreclamebord]

Hi guys,

Just wondering if anyone out here has tried to fit a gear diff from another car in the TRF201? The ball diff I have works nicely, but I'd love to try out a gear diff in it.

I know there is a gear diff for the FF03 by Spec-R, but I heard it's too wide to fit in the TRF201 gear casing. I looked a little further and since the AEB4/4.1, TRF201 and with some parts even the DEX210 share the geometry of parts, I was wondering whether the gear diffs of these might fit. I quickly figured the DEX210 diff wouldn't work due to the very short outdrives. The B4 has imperial sizes but perhaps someone has tried it?

So in short: Anyone got more information on this?

I wonder if the longer 410 outdrives will fit in the 210 gear diff and together make a suitable gear diff for the 201...

As the 210 gear diff isn't available just yet, we'll have to wait and see..

Nice idea! I really hope they are indeed interchangeable. I see in the manual that the gear diff will use the same 9T and 14T gears inside the diff, so the hex shape with which the outdrives fit through the 14T gears will be the same.

The 210 Gear Diff will probably be available soon. Then it's just finding the people who have the parts to try it out, and let's not forget, would like to help us find out!

Well, my 210 gear diff is on back order, I have 410 outdrives, and I might just try it in my 201 GTO... Unfortunately, I don't have a standard 201 gearbox to be positive that the diff will not foul in one. Likewise, it is possible that I may have an issue with the GTo gearbox that isn't there with the std one.

Maybe the TA06 diff is a direct fit?

I use a gear diff on my TRF201 since august.
I use the diff gear form de Kyosho Ultima SC
This diff gear need to modified the gear box.
It's very easy to do it with a dremel...
What pleasure to run with a diff gear!

Cool! I happen to have an Ultima SC so I know how smooth the diff is Just wondering though what exactly needs to be modified to make it fit? Just dremeling the edges a bit so it's a little narrower?

Junior Z: It would be great if you could post a couple of pictures of your modifications and maybe let us know what Kyosho parts are needed

Hi Perli,

To adapt the diff gear must be changed as the red area on the image below. It's not very difficult to achieve if we take the time and having the right tools ... There are approximately 1 mm in width to win.
