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

Service sleeve for TB-03 front oneway

This machined 7075 aluminium front oneway tube is a replacement component for the TAMIYA TB-03 chassis, model TB03-09. It is supplied as a service-level part for the front drivetrain where a oneway mechanism is fitted, intended for maintenance and tuning work.

The sleeve is CNC-machined from 7075 aluminium to standard hop-up tolerances for alloy parts. It locates within the front differential or oneway housing and pairs with existing bearings and shafts to give a durable interface for the oneway unit without changing ride geometry or primary suspension settings.

Fitment advice: remove the original tube with care, check bearing press-fit and axial clearance before assembly, and only use thread locking compound on hardware that requires it. This part is aimed at improving service life and simplifying drivetrain servicing during setup and track checks.

Choose this tube when replacing worn sleeves or refreshing the front oneway assembly; confirm bearing and shaft tolerances to maintain correct drivetrain clearance.
