Technical Note on 3Racing GB-03/V2/LB Swing Shaft for GB-01

The Tamiya GB-01 Heavy Duty Swing Shaft by 3Racing GB-03/V2/LB is a reinforced replacement designed to deliver firmer swing arm support and reduced compliance under load. Intended for drivers focused on tuning and consistent lap times, the shaft improves repeatability by limiting unwanted flex in the rear assembly. Fitment uses existing GB-01 mounting points and the part integrates with common upgrade paths for suspension and drivetrain refinement.

What setup changes benefit most from this shaft?

Reduced swing arm flex complements stiffer spring and damper setups by preserving intended geometry under corner loads, making tuning more predictable.

Any recommendations for bearing selection?

Use quality bearings with tight tolerances and appropriate load ratings to maximise the shaft benefits and avoid play that undermines handling precision.

Does this part affect weight balance significantly?

The shaft adds minimal mass but improves structural stiffness; any change in balance is negligible compared with the handling gains from reduced flex.
