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

TT-02 drivetrain shaft overview

This graphite main shaft is a scale RC drivetrain replacement designed for the Tamiya TT-02 chassis and supplied by 3Racing as model TT02-08. It is intended to serve as a direct-fit spare or hop-up part that replaces the stock main shaft without altering overall chassis geometry.

Functionally the shaft focuses on rotational stability and consistent engagement with the gearbox and spur gear. Graphite is used here as the stated material to reduce torsional flex compared with some softer stock components, helping maintain predictable drivetrain behavior during tuning sessions and track use.

Installation notes: the part installs where the TT-02 main shaft sits in the gearbox assembly and follows the chassis’ existing mounting and bearing locations. Routine checks of bearing fit and axial play are recommended after installation to confirm correct alignment and to prevent premature wear.

For TT-02 users looking to keep drivetrain behavior consistent while refining gear mesh and transmission response, this graphite main shaft provides a like-for-like replacement with material aimed at improved stiffness and stable rotation.
