This seven-piece hardened steel gear kit is tailored for the Kyosho Mini Inferno ST and Mini Inferno platforms and replaces the internal gears used in the front and rear differentials of 1/10 scale nitro and electric buggies. The parts keep the original geometry while switching to a hardened steel composition for increased wear resistance over stock soft alloy gears.
The set functions as a direct internal swap affecting mesh, backlash and durability. When fitting the parts check gear engagement and bearing condition, maintain pinion to spur alignment, and use light grease on gear faces rather than heavy lubricants that can cause binding. This aftermarket part is designed solely for the differential assemblies on the specified Mini Inferno models.
Ideal for builders wanting a tougher internal gear solution while keeping original fitment and geometry intact.
