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

TT-02 Gear Differential Summary

This hop-up gear differential is a direct replacement unit produced for Tamiya TT-02 chassis maintenance and setup. The gear-type construction is designed to swap in for factory differentials when you want improved driveline feel or to refresh worn internal components. This component is intended for model use only.

Fitment targets TT-02 based builds. Before fitting, check the gearbox shell, spur and pinion mesh, and bearing condition to confirm correct alignment. Installation typically removes the original differential carrier and uses the same mounting points as the standard TT-02 unit.

In setup terms a gear differential changes how torque is shared between driven wheels, affecting corner entry traction and mid-corner stability. This unit is suitable for hobbyists who want a straightforward drivetrain replacement or a baseline hop-up without moving to a ball differential.

Use this gear differential when you need a direct TT-02 drivetrain replacement or want to retain predictable traction characteristics; follow normal gearbox service intervals and use appropriate grease on the gears.
