Hey all, I just picked up a v3 kraton, do I really need to shim my diffs and if so how?

Regardless of version, it's always a good idea to take them out and replace the oil with something heavier as well as shim them properly inside the cup and outside for good gear mesh.Hey all, I just picked up a v3 kraton, do I really need to shim my diffs and if so how?
Is the shimming just to cut down on slop or to make the mesh tighter?

What's the purpose if shimming?Mugen 0206 shim set includes all of the shims required besides the thin shim on left side of bearing which is Tekno.

I use 2-1, 2-1 method behind each set of the planetary gear cross sets.
@Rich Duperbash has a good video of process:

What's the purpose if shimming?
To remove excess slop in the spider gears inside the cup and ring/pinion. Most of the arrma 1/8 trucks are pretty heavy and brushless torque is very harsh on diffs. Out of the box, there may be a bit too much gear lash and it's a good idea to check. Just a bit of preventative maintenance to avoid messing up $120 worth of diffs prematurely. Diffs are around $30-$40 on ebay. Or at least the last one I bought was.What's the purpose if shimming?

I think you have it. It is for both purposes I feel. I run 60/200/30k diff oil front/center/rear for reference. I may switch to 500k center over the winter maintenance.
Thicker in front reduces the front diff from unloading as much and turning the tires into pizza cutters.
