TOPIC:

I have a mate that have the black Anneversary 934 RSR TA02SW.

Or rather it's his son that owns that car.
Problem is the splines into the balldiff are now gone, not on the outdrive cups, which I belive are the hardened type.
Are there any hardned diff sides available for this, from Tamiya or aftermarket?
Or is he simply have to replace the worn parts for stock items?

Don't know which motor they are using, but it's powerful.
His dad used to race on-road cars, so when he says powerful, I belive he means exacly that...

You can use the top force evo sides.

Flo those are even softer (aluminium)
Trick is to keep the outdrives in place if there is to much play and power on them thew will strip the splines. Either some glue or the o-rings trick
Or switch to gear diffs those are more stable than the balldiffs under pressure. (Wider spines)

Thank you both

Ill report back to him
