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

Replacement front oneway tube for TB-03

This 7075 aluminium front oneway tube is an RC-scale replacement part for the TAMIYA TB-03 chassis, model TB03-09. It is intended as a service and maintenance component in the front drivetrain where a oneway action is required.

Manufactured from 7075 aluminium and machined to common hop-up tolerances, the tube fits within the front differential or oneway housing and interfaces with the existing bearings and shafts to provide a stable sleeve for the oneway mechanism without altering key suspension geometry.

Installation notes: remove the old tube carefully, check bearing fit and endplay prior to final assembly, and apply thread lock only where hardware indicates. The part is intended to improve durability and ease front drivetrain servicing during setup or track maintenance.

Use this tube when refreshing the front oneway assembly; ensure bearings and shafts are correctly matched to maintain design clearances.
