This aluminium center shaft cup joint is an aftermarket replacement intended for Kyosho Fazer Mk2 FZ02 maintenance and tuning. It replaces stock plastic or standard metal cups to improve the center driveline connection and offer better wear resistance while keeping stock geometry.
Installation is straightforward: remove the center shaft assembly, fit the cup joint onto the shaft end ensuring proper spline engagement, then reassemble and check clearances. Use common hobby tools and take care not to overtighten retainers to avoid binding.
In tuning scenarios this joint helps address driveline play and supports consistent handling during practice and setup sessions. The aluminium construction provides reliable wear behavior suitable for routine servicing and gradual performance tweaks on the Fazer Mk2 FZ02.
