Default Gearing

I use a 42, 43, 44, tooth pinion 96 spur for 540 silver can and my evo III is very very fast.

Default 540 stock

I use a 36-38 tooth pinion on a 96 pinion you can use this to determine what pinion range you should start with pinion size = rollout ex 40mm x driv ratio ex 2.4 for pro 4 x spur size /197.9208
equation would be 40mmx2.6x96/197.9208 50 tooth to get a rollout of 40mm but stock motor may not run real good like this might not be able to use the full rpm curve.

Read the prior posts on this page on gear stripping. Shimming is just adding or removing spacers between the outdrive bearings and diff to adjust the mesh between the ring and bevel gears. proper mesh is important to minimize gear breakage. There's a new light weight center shaft that's supposed to help too.

No. A diff allows some give if you hit something so you're less likely to break but it can still happen. Shimming is still the best thing you can do to avoid breakage

Shim the gear towards the bevel gear (shim behind the bearing) until the lash is almost gone...but not so much that it binds up. It takes some playing around to get it right, but it works REALLy well.

I carry a few gears with me just in case, but I haven't used one in months. They're cheap ($3 or so) and they take 5 minutes to change, so don't lose a bunch of sleep over it.

With these shims, adjust the play by adding shims between the bearing and the one-way, usually on the same side as the big gear.

Hmm, I never heard of breaking gears using a frontdiff. But usually I used a oneway not a frontdiff. But after switching to the Jürgen oneway I broke just one gear within 1 year of use.
