GB-01/GB-02 Swing Shaft Heavy Duty Ver.2 Tamiya GB-03/V2/LB by 3Racing  [GB-03/V2/LB]

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

This heavy duty replacement swing shaft fits Tamiya GB-01 and GB-02 chassis and is identified as GB-03/V2/LB. It is offered as an aftermarket hop-up part to address drivetrain wear that occurs in regular hobby use.

Install this shaft to substitute a bent or worn unit and to reduce flex during demanding driving or repeated practice. The Heavy Duty Ver. 2 designation indicates a focus on improved durability and stable alignment rather than altering suspension geometry.

Fitting advice: confirm the fit with your current bushings or bearings, check axle alignment post-installation, and ensure wheels rotate freely before full-throttle runs. Treat this component as a drivetrain upgrade accessory for scale RC models.
