This precision-machined aluminium one way hub is produced as part number FW05-010 for use on Kyosho FW05-R and FW05RR chassis. The alloy construction increases contact rigidity, reducing micro-deformation at engagement points and delivering more consistent mechanical response during tuning and competition use.
Performance note: the hub alters driven-wheel decoupling characteristics under dynamic loads, producing a crisper engagement profile that benefits differential setup and repeatable traction transitions at the limit. Use standard FW05 bearings and spacers and verify axial play after assembly to maintain correct preload.
Assembly guidance: the hub is manufactured to OEM FW05-R/FW05RR mounting dimensions. Inspect carrier alignment, confirm thread and fastener compatibility, and perform a controlled run to validate clearance, engagement timing and torque retention.
For precise differential tuning and a repeatable mechanical feel on FW05 chassis choose this aluminium hub, and follow standard inspection and torque procedures after installation.
