Kyosho FA503B - Hub Set FZ02 for FAZER RAGE 2.0 / FZ02 Mk2  [KY-FA503B]

Hub set overview

This hub set is an RC-scale replacement hub assembly intended for Kyosho FAZER FZ02 on-road models, listed under FA503B. It serves as a direct spare for the hub area and is presented as a maintenance or tuning component rather than a performance upgrade on its own.

Compatibility is focused on FAZER RAGE 2.0 and FZ02 Mk2 platform references provided with the part listing. Verify chassis code and visual match with your existing hub carriers before installing to ensure fitment, because hub geometry and bearing placement must align exactly with the stock components.

Installation notes: remove the wheel, brake discs or drums as required, and access the hub carriers following your model’s standard disassembly steps. Replace the hub components cleanly, check for correct bearing seating, and confirm axle retention hardware torque matches the chassis recommendations. Use thread locker only where specified by your model manual.

Tuning role and maintenance: this hub set is primarily a service part used to restore correct alignment, eliminate play from worn hubs, or return a crashed chassis to serviceable condition. It can affect steering feel and toe/alignment consistency when worn or damaged, so inspect and replace hubs as part of routine maintenance on on-road FAZER cars.
