KYOSHO TORSON RACE DIFF MOD OPTION...

What can I say, a $300.00+ dollar trick... not a cheap mod

I made spacers for the smaller bearing on the kyosho diff to fit in the NTK housing, but I remember checking Boca bearing afterwards and I think they had a proper sized bearing that would of worked too. The gear I used on the torson was a stock delerin NTK gear that had the center melted out of it because it was run to loose which fit just right with a bit of triming, I used j/b weld to fill in the gap on the inside of the gear and used set screws to bolt it on. If I remember right the key to using this type of diff was to use a diff with a max of 24mm center diameter which this on is so it does not interfere with center tranny gear.
