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

Upgrade rear hub for GB-01 chassis

This rear aluminium hub is compatible with Tamiya GB-01, GB-01T and GT-01 models and comes in a light blue anodised finish with a 3 degree offset for rear-end setup changes. It replaces the original plastic hub to offer a metal alternative that alters the suspension geometry by the stated angle.

Fitting is simple for those used to the GB-01 platform: the part uses the stock mounting points and wheel retention hardware so no bespoke machining is needed. Always verify alignment and torque to the chassis manual after installation.

From a tuning perspective the 3 degree offset changes rear track and toe slightly, letting you tune balance depending on surface and driving style. Combine this change with shock and spring tuning and evaluate each change in isolation for best results.
