This is an aluminum rear hub carrier designed for the Tamiya TA05-IFS and TRF-416 chassis, sold under 3Racing part number TA05-IF14/0/LB. As an RC-scale replacement part, it provides a rigid mounting point for the rear wheel hub and contributes to the rear suspension geometry used in on-road setups.
The 0 degree designation describes the carrier's fixed caster/roll-center orientation relative to the hub mount. Swapping a hub carrier alters how the rear suspension reacts under acceleration, braking and cornering, so this component is used primarily for small geometry adjustments when tuning handling balance on paved tracks.
Installation is a direct swap on compatible rear assemblies: remove the existing hub carrier from the rear upright assembly, fit this aluminum unit in the same position, and secure with the original hardware. After installation check wheel alignment, bearing fitment and rear toe to ensure expected behavior before running at full speed.
Use this part when you need a more rigid rear mounting point for consistent handling during practice or track sessions, and when you are tuning rear-end grip or transient response without changing major suspension components.
