TAMIYA TT-02 12mm Aluminum Wheel Hex Hub Upgrade - TT02-13123-LB by Jazrider  [TT02-13123-LB]

12mm Wheel Hex Hub Designed for TT-02

This is an aftermarket aluminum wheel hex hub intended for the TAMIYA TT-02 chassis. The unit is a 12mm hex with an integrated locker and is finished in light blue to make it easier to spot among other parts.

The item replaces the standard wheel hex or adapter to establish a metal mounting interface between the wheel and axle, improving positional repeatability across repeated wheel changes and maintenance cycles. Aluminum provides a different wear profile compared to common plastic hexes, which can matter when swapping wheels often.

How to fit: remove the wheel and existing hex from the TT-02 wheel assembly, insert the aluminum hex into the hub bore, align the locker to the wheel mounting surface, and reinstall the wheel using the chassis' original fastening steps. Always confirm correct seating and acceptable runout before use.

Use case for tuning: this hub is aimed at drivers who need a reliable metal interface for consistent wheel mounting during setup work; it does not change suspension geometry but improves mounting repeatability.
