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

Service replacement for TT-01 differential

This hop-up replacement differential gear fits the Tamiya TT-01 platform and is listed specifically for compatibility with the TT01-05/LB variant. It is intended as a direct, serviceable replacement to keep the TT-01 drivetrain running reliably during tuning and repairs.

Fitment and role: supplied as a drop-in replacement for the TT-01 diff housing, the gear interfaces with the standard spur and pinion arrangement used on the TT01-05/LB chassis. Its purpose is simple: restore correct gear mesh and predictable differential action for everyday setup changes or routine maintenance.

Installation notes: swapping this part requires disassembly of the TT-01 differential housing. Inspect gear mesh and running clearances after installation, reuse the vehicle's original screws and retainers, and verify smooth rotation before returning the car to full use. No special machining or unusual tools are required beyond normal hobby practice.
