This machined aluminium centre shaft cup is an aftermarket replacement designed for the KYOSHO Fazer Mk2 FZ02 on-road chassis. It interfaces with the centre shaft assembly to transfer torque from the gearbox to downstream drivetrain components.
Use it to replace worn plastic cups and reduce rotational play at the centre connection, giving a steadier drive feel while adjusting gear mesh and preload. The aluminium construction improves wear resistance over stock materials while retaining the correct profile for Fazer Mk2 FZ02 installation.
Fitment notes: check alignment with the existing centre shaft and refit using original fasteners. Long-term installations may benefit from cleaning mating faces or trimming small clips. Fit with suitable hobby tools and avoid excessive tightening to protect surrounding gearbox parts.
