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

GB-01 rear hub upgrade

This aluminum rear hub fits Tamiya GB-01, GB-01T and GT-01 chassis and is anodized light blue with a 3 degree offset for subtle rear-end tuning. It replaces the standard plastic hub to provide a metal option that adjusts suspension geometry by the specified angle.

Installation is straightforward for modelers familiar with the GB-01 range: the hub uses the chassis original mounting points and the existing wheel retention hardware, so no extra machining is required. After fitting, confirm alignment and fastener torque against the chassis manual to ensure safe running.

On track the 3 degree offset slightly changes rear track and toe, letting you refine handling balance alongside shocks, springs and tyre choice. Make adjustments one step at a time to isolate the hub's effect in your setup process.
