This aluminum center shaft cup joint is an RC-scale replacement part intended for the Kyosho Fazer Mk2 FZ02 on-road chassis. It serves as a direct drivetrain coupling component, designed to interface with the center shaft assembly and transfer torque between gearbox outputs and downstream drivetrain elements.
In practical RC use the part is used to replace worn plastic or deformed cups, reduce rotational play in the center shaft connection, and support consistent drive behaviour when tuning gear mesh and drivetrain preload. The machined aluminum body offers greater wear resistance compared with typical stock materials, while keeping the form factor appropriate for Fazer Mk2 FZ02 installation.
Installation notes: verify fit against the existing center shaft and secure with the original fasteners. Minor trimming of adjacent shaft clips or light cleaning of mating surfaces may be required after long service periods. Use appropriate hobby tools and avoid over-tightening to prevent stress on surrounding gearbox components.
