You need a hardened steel pinion when using a steel spur. Hot Racing and Robinson Racing make some good steel pinions.

The next place to fail is the weakest link. Metal is stronger then plastic.
Also, more gears in diff compared to spur to pinion.
I run metal everything, but spur gear. Easier to swap spur, then to rebuild others.

Go with the steel hardened pinion. When you set the mesh make sure you push the motor against at the same time you tighten the motor screws. That paper should only come out if you turn the pinion. When i installed my 4000kv tazer setup i had to barely notch out the slotted motor ajustment hole to achieve proper mesh. I still run all plastic gears and i adjusted my slipper clutch to. All the way in and then 2 turns out. That way the diff will live for a while. Whatch landing at full throttle and dont set your brakes on the esc real strong. If you are locking up the tires going forward its ruff on the diff. I have had 6 wide open runs for 20 minutes at a time and its living pretty well sofar.

Also with stock diff no batteries bigger than 2s lipo.
