Kyosho st rr with os 28 engine
 

Hello,

What is the good starting diff oil set up
for st-rr with os28.

Thanks...

front 10k
center 10k
rear 5k

And when your changing diff fluids u mite wanna check wear because that 28 in the strr is super super hard on diffs don't be surprised if your replacing ring n pinions left n right if your driving on high bite tracks.

Yea man,that OS28 is gonna eat those diffs up bigtime.Might want to try a .21.Good luck.

i ran a highly modded 427 in my strr i ran 7 front 20 center 3 rear on high bite track you cannot hurt them cromemoly diff gears in that truck my gears are in great shape

Thanks all

7/20/5 for now.
