Tamiya TT-02 Gear Differential Replacement TT02-09 by 3Racing  [TT02-09]

Overview of TT-02 Gear Differential

This hop-up gear differential is supplied as a service and tuning replacement for Tamiya TT-02 chassis. The gear-style internals are intended to replace worn or stock differentials when you want consistent driveline behaviour. It is for model use only and not for any full-scale application.

Fitment is focused on TT-02 layouts. Before fitting, inspect the gearbox housing, ensure correct spur and pinion mesh, and check bearings for free rotation. The differential typically replaces the factory carrier and uses the same mounting points as the original TT-02 differential.

On a handling level, a gear differential affects torque distribution between driven wheels, which influences corner exit traction and mid-corner stability. This part suits hobbyists who want a straightforward drivetrain swap or a base hop-up without the complexity of a ball differential.

Fit this gear differential to keep TT-02 drivetrains predictable; perform routine gear maintenance and use the appropriate grease to protect the teeth and bearings.
