The seven-piece hardened steel gear set fits the Kyosho Mini Inferno ST and Mini Inferno chassis to replace the front and rear internal differential gears typically fitted to 1/10 nitro and electric buggies. These gears keep the original tooth profiles while using hardened steel for superior wear resistance compared to softer stock materials.
Installed as a direct replacement for the differential internals, the set will affect gear mesh and backlash and increase long-term serviceability. When fitting the gears inspect bearings and housing faces, maintain correct pinion and spur alignment, and use a light gear grease on mating surfaces instead of heavy pastes that can hinder rotation. This is an aftermarket RC component intended for the listed Mini Inferno differentials.
A straightforward upgrade for hobbyists seeking hardened internals without changing the car's gear geometry.
