Tamiya TT-02 Graphite Main Shaft TT02-08 by 3Racing  [TT02-08]

Overview of the TT-02 graphite main shaft

This graphite main shaft is a scale RC drivetrain replacement for the Tamiya TT-02 chassis, supplied as model TT02-08 by 3Racing. It fits as a direct replacement for the stock main shaft without changing the chassis geometry.

The shaft is designed to improve rotational stability and keep consistent engagement between the gearbox and spur gear. Graphite is specified to lower torsional flex compared with softer stock items, helping maintain predictable drivetrain behaviour during tuning and on-track use.

Installation notes: this part installs in the same gearbox location as the original TT-02 main shaft and uses the chassis' existing bearing and mounting points. After fitting, inspect bearing fit and axial play to ensure correct alignment and to avoid premature wear.

For TT-02 owners aiming to stabilise gear mesh and transmission response, this graphite main shaft delivers a like-for-like replacement with increased stiffness for steadier rotation.
