TAMIYA TB-03 Front oneway tube 7075 aluminium TB03-09 by 3Racing  [TB03-09]

Front oneway tube for TB-03 maintenance

This aluminium front oneway tube is an RC-scale replacement part for the TAMIYA TB-03 chassis, model TB03-09. It is intended as a serviceable component in the front drivetrain where a oneway action is required, helping hobbyists maintain or tune TB-03 vehicles.

The tube is produced from 7075 aluminium and machined to suit common alloy hop-up tolerances. In use the sleeve locates inside the front differential or oneway housing and works with existing bearings and shafts to provide a stable, long-lasting interface for the oneway mechanism without changing suspension geometry.

Installation notes: remove the worn factory sleeve carefully, verify bearing seating and endplay before final assembly, and apply RC-safe thread lock only where hardware specifies it. This tube is a component-level upgrade focused on serviceability and extended life during regular setup and track sessions.

Use this sleeve when replacing worn parts or refreshing the front oneway assembly; match bearings and shaft tolerances to preserve intended drivetrain clearances.
