Tamiya GB-01 Swing Shaft Heavy Duty Ver.2 by 3Racing GB-03/V2/LB  [GB-03/V2/LB]

Heavy-duty swing shaft for GB-01/GB-02

This is a heavy duty replacement swing shaft intended for Tamiya GB-01 and GB-02 scale chassis, supplied under 3Racing designation GB-03/V2/LB. It is presented as an upgraded hop-up part to address wear points in the drivetrain on hobby-grade RC models.

Use this part to replace a worn or bent swing shaft and to reduce flex under load during aggressive cornering or frequent practice sessions. The part is described as "Heavy Duty Ver. 2," so expect a focus on durability and repeatable alignment rather than altering suspension geometry.

Installation notes: verify fit with existing bushings or bearings on the GB-01/GB-02 suspension arms, check axle alignment after installation, and confirm smooth wheel rotation before full-speed runs. This shaft functions as a direct drivetrain component in RC-scale models and should be handled as an accessory for model use only.
