3Racing TAMIYA GT-01 Ball Differential Service Shaft GT-03/LB - Replacement Part  [GT-03/LB]

Service replacement for GT-01 ball differential

This anodized aluminium shaft, finished in light blue and identified as GT-03/LB, is supplied as a replacement for the TAMIYA GT-01 ball differential assembly. It is intended for routine service and to replace worn original shafts.

Use the shaft when rebuilding the GT-01 ball differential to restore correct alignment and preserve diff internals. It is designed to integrate with the existing assembly rather than to act as a standalone tuning change.

Fitment guidance: remove the diff housing and follow standard GT-01 ball-differential rebuild procedures, transfer bearings and balls where necessary, and set endplay and preload accurately at reassembly for consistent operation.
