TAMIYA GB-01 Aluminum Rear Hub 2 Degree GB-04/2/LB by 3Racing  [GB-04/2/LB]

Aluminum rear hub for GB-01 chassis

The GB-04/2/LB is a light blue anodized aluminum rear hub made for TAMIYA GB-01, GB-01T and GT-01 chassis, supplied as a 2 degree option to alter rear wheel geometry. It is produced to align with the stock hub footprint while introducing the 2 degree angle change.

This metal hub is intended as a tougher replacement for plastic hubs when you need more predictable handling under load. The alloy construction offers improved consistency and the small offset helps fine-tune rear tracking and corner behaviour for tighter setups.

Fitting is straightforward and mirrors the original hub process: remove wheel and nut, detach the stock hub from the rear upright, fit the GB-04/2/LB and reassemble using the vehicle's existing hardware. Typical hobby tools such as a hex driver are suitable, provided the upright and axle follow GB-01 series dimensions.

For model-only use and chassis tuning purposes; always verify fitment on your vehicle before high-stress running.
