Kyosho Mini Inferno ST / Mini Inferno Hard Steel Gear Set for Front/Rear Differential Assembly (7pcs) by GPM SMIF1202  [SMIF1202]

Hard Steel Front/Rear Differential Gear Set

This 7pcs hard steel gear set is made for the Kyosho Mini Inferno ST and Mini Inferno chassis, intended to replace the front and rear differential internal gears in scale 1/10 nitro/electric buggies. The kit provides direct-fit replacement gears that retain original geometry while using hardened steel for increased wear resistance compared with stock soft alloys.

Technically the set serves as a direct drivetrain internals swap, affecting gear mesh, backlash, and long-term durability. When installing, check gear mesh and bearing condition, keep pinion and spur alignment, and use appropriate light grease on gear faces rather than heavy pastes that can bind. This part is an RC-scale accessory only and is designed to work inside the differential assemblies of the listed Mini Inferno variants.

Suitable for builders and tuners wanting a hardened replacement for Mini Inferno front and rear differential internals without modifying the chassis geometry.
