3Racing Tamiya TB-03 7075 Aluminium Differential Shaft TB03-07 - RC Spare Part  [TB03-07]

7075 Aluminium differential shaft for TB-03

This 7075 aluminium differential shaft is a direct-fit replacement for the Tamiya TB-03 chassis, intended as a robust spare part for drivetrain maintenance and repair. The component replaces worn or damaged stock shafts while retaining original fit and alignment in the TB-03 differential assembly.

Installation advice emphasises fit and orientation: remove the differential housing, inspect internal gears and bearings for wear, then slide the shaft into place making sure it engages correctly with the differential internals. Reassemble in reverse order and check for binding or excess play; perform a bench rotation test before returning the car to use.

As part of a setup or servicing routine this shaft works as a maintenance or incremental upgrade option that preserves chassis geometry while providing the dimensional consistency of a machined 7075 aluminium part. It is suitable for routine repairs, spares stock, and small drivetrain tuning on TB-03 builds.
