The GB-04/0/LB is an aluminium rear hub engineered for use on Tamiya GB-01, GB-01T and GT-01 chassis. Supplied in a 0 degree orientation with a light blue finish, the component replaces the standard plastic hub to provide a stable metal mounting surface at the rear hub locations.
Fit and role: designed to mirror the rear hub mount geometry of the listed Tamiya platforms, this hub secures wheel retention hardware and suspension link attachments while maintaining neutral rear geometry in its supplied orientation.
Installation notes: install using standard GB-01 hub replacement procedures, verify correct fastener selection and torque, and confirm bearing condition and wheel clearance following fitment. Recheck alignment after test runs to validate setup.
Tuning guidance: use this aluminium rear hub as a consistent datum point when calibrating rear geometry, evaluating suspension settings, or when a metal finish is preferred for the rear axle area.
