The JR-KFZ202-BK kit includes two aluminum front/rear wheel shafts intended for Kyosho Fazer Mk2 FZ02 on-road cars. These parts replace standard plastic shafts to create a metal interface with the wheel hub where compatible, and compatibility is listed at the model level.
Finished in black anodized aluminum, the shafts are sold as a pair for front and rear use. They serve to retain the wheel and keep rotational alignment, offering a simple replacement or modest durability improvement without affecting drivetrain geometry.
Installation notes: intended for Fazer Mk2 FZ02 hub assemblies that accept a direct shaft element; verify fitment prior to assembly. Remove wheel hardware with standard hobby tools, trial-fit the shaft, and confirm free rotation before use. No further machining is described.
Tuning and upkeep: aluminium shafts can reduce wear on mating plastic components and provide a firmer locating surface for repeatable wheel positioning during maintenance. After installation check bearings and hub interfaces to ensure correct seating and to prevent binding.
