TAMIYA GT-01 Ball Diff Service Shaft GT-03/LB by 3Racing  [GT-03/LB]

Service shaft for GT-01 ball diff

This aluminium shaft, anodized in light blue and tagged GT-03/LB, is supplied as a replacement for the TAMIYA GT-01 ball differential assembly. It is offered for routine maintenance and as a like-for-like shaft when the original shows signs of wear.

Use the part when rebuilding the GT-01 ball differential to retain correct assembly alignment and functional fit with the diff internals. It is intended to be integrated into the existing drivetrain components rather than used as a standalone modification.

Rebuild guidance: remove the diff housing, follow standard GT-01 ball-differential service steps, transfer bearings and balls where needed, and confirm endplay and preload at reassembly to maintain reliable diff behavior.
