Overview
This Tekno RC differential ring gear has 40 teeth and is made for the ET410 1/10 4WD electric truggy. It is designed to run with the TKR7222 10T diff pinion.
The ring and pinion transfer power through the front and rear differentials. Worn or chipped teeth cause noise and lost drive, so replacing the ring gear restores smooth, quiet power delivery.
