The FA503B hub set is a direct replacement hub assembly for Kyosho FAZER FZ02 on-road cars. It is intended as a maintenance and repair component to restore original hub geometry and alignment.
This item lists compatibility with FAZER RAGE 2.0 and FZ02 Mk2 chassis references. Prior to fitting, check that your hub carrier layout and bearing locations match the replacement parts to avoid fitment issues.
Fitting guidance: remove the wheel and any brake discs or drums needed to access the hub carriers, then follow your standard disassembly process. Ensure bearings are pressed in squarely, and confirm axle hardware torque conforms to your chassis handbook. Use thread locker sparingly and only where the manual advises.
Role in tuning and maintenance: primarily a service part to correct worn or damaged hubs. Replacing degraded hubs reduces steering slack and helps preserve accurate toe and tracking on FAZER on-road models.
