Tamiya TT-01 Drivetrain Differential Gear TT01-05/RG for TT01-05/LB by 3Racing  [TT01-05/RG]

Direct replacement diff for TT-01

This hop-up replacement differential gear is intended for the Tamiya TT-01 family and listed for the TT01-05/LB variant. It is aimed at hobbyists who need a straightforward, serviceable replacement to keep the TT-01 drivetrain functioning correctly.

Fitment and role: designed to fit the TT-01 diff housing and engage with the stock spur and pinion found in TT01-05/LB chassis. The part restores correct gear meshing and standard differential action so handling and power transfer remain predictable after repairs or setup changes.

Installation notes: basic diff housing disassembly is required to swap the gear. Inspect gear mesh and clearances after installation, reuse original screws and retainers, and confirm free rotation by hand before driving. Typical hobby tools suffice for the job.
