Racing-oriented 2 degree rear hub for GB-01 platforms

The GB-04/2/LB is a light blue anodised aluminium rear hub specified for TAMIYA GB-01, GB-01T and GT-01 chassis to provide a 2 degree geometry option while maintaining the OEM hub footprint. It is intended as a tuning part for drivers refining rear tracking and corner behaviour.

Use this hub to obtain a firmer, more repeatable rear response compared with common plastic hubs; the 2 degree offset enables controlled adjustments to rear roll and tracking for competitive setups. The aluminium construction supports consistent behaviour during repeated runs and setup iterations.

Installation procedure mirrors the stock part: remove wheel and nut, unbolt the factory hub from the rear upright, install the GB-04/2/LB and reassemble with stock fasteners and wheel hardware. Verify upright and axle compatibility with GB-01 series dimensions before high-load use.

This component is intended strictly for model RC chassis tuning; validate fit and clearances on your vehicle prior to competitive use.

What setup changes pair well with a 2 degree rear hub?

Pair the 2 degree hub with small adjustments to rear camber and shock damping to evaluate combined effects on rotation and traction. Make one change at a time to isolate results.

How should I test handling after fitting the GB-04/2/LB?

Conduct controlled track runs, compare lap consistency and turn-in behaviour versus baseline, then iterate settings based on observed understeer or oversteer.

Any common fitment checks before installing?

Confirm rear upright hub bore, axle diameter and wheel clearance. Ensure the vehicle's fasteners are in good condition and torque to correct values after assembly.
