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

Front oneway tube for TB-03

This aluminium front oneway tube is an RC-scale replacement part intended for the TAMIYA TB-03 chassis, offered by 3Racing as model TB03-09. It serves as a direct-service component in the front drivetrain assembly where a oneway action is required, and is presented for hobbyists who maintain or tune TB-03 cars.

The part is manufactured from 7075 aluminium and is machined to typical tolerances for alloy hop-up components. In practical use the tube locates within the front differential or oneway housing and interfaces with existing bearings and shafts; the intent is to provide a stable, durable sleeve for the oneway mechanism rather than alter geometry or primary suspension settings.

Installation notes: replace the factory tube with care, confirm bearing fit and endplay prior to final assembly, and use standard RC-safe thread locking only where hardware requires it. The tube is a component-level upgrade for serviceability and longevity and can be used as part of stepwise drivetrain tuning on-track or during setup sessions.

Use this tube when removing worn sleeves or when replacing the front oneway component during routine maintenance; match bearings and shafts to retain intended drivetrain clearances.
