Tamiya TB-03 Aluminium 7075 Differential Shaft by 3Racing TB03-07  [TB03-07]

Aluminium differential shaft for TB-03

This 7075 aluminium differential shaft is a direct-fit replacement designed for Tamiya TB-03 chassis users who need a durable spare part for drivetrain maintenance. The component is presented as an RC-scale shaft intended to replace worn or damaged stock parts while keeping original fitment and alignment for the TB-03 differential assembly.

Installation notes focus on fit and orientation: remove the differential housing, inspect internal gears and bearings for wear, and slide the shaft into position ensuring correct engagement with differential internals. Reassembly follows the reverse order while checking for binding or play; final verification on the bench before track use is recommended.

In a tuning workflow this shaft serves as a maintenance or upgrade option that maintains chassis geometry while offering the dimensional consistency of a machined 7075 aluminium part. It is suitable for routine repairs, spares inventory, and incremental drivetrain adjustments on TB-03 setups.
