Modelers upgrading a TB-01 or TB-Evolution can fit the Tamiya 49238 Hard 0.6 Spur Gear 88T to improve driveline stiffness. Crafted in black resin, the component is intended to deliver reliable, repeatable gear engagement.
The part is made to match TB-01 and Evolution gear trains and swaps in place of the OEM spur. Installation follows normal spur replacement procedures with only basic tools required.
The hard resin material is chosen to resist wear and keep gear mesh consistent during club runs and regular use, reducing the frequency of replacements.
