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

Stiffer swing shaft for GB-01 and GB-02 models

This heavy duty replacement is made for Tamiya GB-01 and GB-02 scale chassis and is supplied as designation GB-03/V2/LB. It functions as an upgraded hop-up to tackle drivetrain wear and weak points found in regular use.

Use this shaft to replace bent or worn originals to limit deflection during aggressive driving and to maintain consistent alignment. The Heavy Duty Ver. 2 emphasis is on robustness and repeatable fit rather than suspension changes.

Fitment notes: check the condition and clearance of your bushings or bearings, ensure correct axle alignment following installation, and verify smooth wheel rotation before full-speed testing. This is an aftermarket drivetrain accessory for model use only.
