Robinson Racing Products Hard Blackened Steel Mini Pinion 2mm .5 Mod 18T RRP1818 Gears & Differentials

Fits perfectly and machined true so there is no wobble or misalignment issues. Definitely holds up much better than the original pinion gear! Especially since I'm running a hardened steel spur gear instead of the stock plastic one.

Robinson makes some pretty good gears. Using one in a brushless way over geared latrax rally and one in a brushless trx4. Both brushless and both holding up no problem
