TAMIYA TT02/TT02B Small Bevel Gear Set Steel TT2100/G4 by GPM  [TT2100/G4]

Durable steel small bevel gears for TT02 differentials

This set contains four steel small bevel gears intended as replacement hop-up parts for TAMIYA TT02 and TT02B chassis. The gears are sized for differential and internal gear train use, with an emphasis on durability and consistent mesh under normal running.

These small bevel gears transfer torque inside the differential and gearbox assemblies to mate with other bevel gears. Choosing steel over softer alloys improves wear resistance for models that see frequent running or operate with heavier power systems.

Fitment advice: remove the diff carrier, inspect mating bevels and bearings, fit the steel small bevels in the correct orientation, and check mesh before final assembly. Use the diff fluid or grease recommended for your TT02 differential and make sure the drivetrain rotates smoothly.

The TT2100/G4 steel small bevels are a practical swap for owners wanting longer-lasting bevels in the TT02 drivetrain; always confirm fit and mesh on your own diff build before sustained use.
