TAMIYA TT02/TT02B Small Bevel Gears Steel Upgrade TT2100/G4 by GPM  [TT2100/G4]

Steel small bevel replacements for TT02 builds

This four-piece set provides steel small bevel gears as replacement hop-up parts for TAMIYA TT02 and TT02B chassis. They are intended for the diff and internal gear trains where improved wear resistance and steady mesh are useful for regular use.

Functionally these bevels sit in the differential and gearbox to transfer torque between mating gears. The steel option offers better wear resistance than typical soft alloys, helping when models run often or when using higher torque motors and heavier setups.

Installation notes: remove the differential carrier, inspect the mating bevels and bearings for wear, install the steel small bevels with correct orientation, and verify gear mesh prior to final reassembly. Use the correct diff fluid or grease for your TT02 differential and confirm free rotation through the drivetrain.

The TT2100/G4 steel small bevels are a simple, robust replacement to keep a TT02 drivetrain running longer; always confirm mesh and clearances on your specific diff assembly before extended use.
