FAZER D2 Spool Cup, Steel Construction

This steel spool cup is sized for the FAZER D2 chassis kit as a direct replacement component for the spool assembly. The FZD2 marking identifies its specific fit and location inside the FAZER D2 drivetrain layout.

Choosing steel delivers a tough bearing surface where the spool engages surrounding bearings and differential parts. During inspections this cup is commonly checked and renewed if wear or poor seating is discovered.

Installation is aimed at hobbyists comfortable with on-road models: remove the diff or spool unit, assess bearings and seals, replace the cup keeping fastener and spacer order intact, and ensure unobstructed rotation before final reassembly. No specialist tools beyond standard hex drivers are typically needed.

Functionally this item is a replacement part rather than a performance kit; accurate seating and low play help maintain consistent spool engagement and predictable handling. Model builders usually confirm bearing fit and mating surfaces during final setup and run-in checks.
Remark :
Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How does steel compare to other materials for the spool cup?

Steel offers superior wear resistance for the mating surface; it holds up well under repeated service compared with softer alloys or plastics.

Will the steel cup corrode over time?

Steel can corrode if exposed to moisture and salt; keep parts clean and lightly oiled, and consider corrosion prevention if you run in damp environments.

When should I replace the cup during maintenance?

Replace the cup when you observe scoring, excessive play, or if bearing seating becomes unreliable; these signs indicate the part has reached end of service life.

Any torque or fastener notes for reassembly?

Maintain original fastener order and tighten evenly; avoid over-torquing which can misalign spacers and affect spool rotation.
