Tamiya GB-01/GB-01T/GT-01 Rear Aluminium Hub 3 Degree Track-Tuning GB-04/3/LB by 3Racing  [GB-04/3/LB]

Rear aluminium hub for GB-01 family

This light blue anodised rear aluminium hub is made for Tamiya GB-01, GB-01T and GT-01 chassis and features a 3 degree offset to assist rear-end setup adjustments. It is intended to replace the stock plastic hub with a metal component that changes suspension geometry by the specified amount.

Installing the hub is straightforward for hobbyists familiar with the GB-01 series: it uses the chassis original mounting locations and the existing wheel retention hardware, so additional machining is not required. After installation, confirm alignment and torque to the manufacturer's recommendations.

In practical tuning terms, the 3 degree offset subtly shifts rear track and toe, which can help dial in balance for different surfaces or driving preferences. Use this hub alongside shock and tyre changes and evaluate each step to understand the handling impact.
