Replacement Steel Spool Cup for FAZER D2

This RC-scale steel spool cup is produced to match the FAZER D2 chassis kit and serves as a direct spare for the spool assembly. The FZD2 designation identifies its specific location and role within the FAZER D2 drivetrain layout.

Steel construction and accurate geometry provide a long-wearing contact surface where the spool meets surrounding bearings and differential parts. During routine servicing this cup is commonly inspected and swapped when the original shows scoring or poor fit.

Installation is straightforward for hobbyists experienced with on-road kits: remove the spool or diff assembly, check bearings and seals, replace the cup while maintaining fastener and spacer order, and confirm free rotation before final assembly. Typical hex drivers and basic workshop supplies are all that are required.

As a structural replacement, this cup supports consistent spool engagement rather than acting as a standalone tuning upgrade; correct fit and minimal play help preserve predictable spool response on drift setups. Enthusiasts will normally verify bearing seating and mating surfaces during corner-weighting and toe 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.

Can I use this cup in any FAZER D2 build?

This cup is specified for the FAZER D2 chassis spool assembly; confirm your kit's parts list to ensure compatibility before ordering.

Should I replace bearings when fitting the new cup?

Inspect bearings for roughness or lateral play; replace worn bearings, otherwise clean and relubricate them prior to reassembly.

Will swapping to steel change how the car handles?

As a like-for-like spare, the steel cup preserves intended fit and durability; any handling differences are usually caused by diff or suspension settings rather than the cup alone.

Any reassembly tips after replacing the spool cup?

Keep fasteners and spacers in their original order, tighten evenly, and verify the spool rotates freely before using the car on-track.
