This aluminium centre shaft cup joint is supplied as a replacement item for the KYOSHO Fazer Mk2 FZ02 on-road chassis. It is designed to couple with the centre shaft assembly and carry torque from the gearbox to downstream drivetrain elements.
In practical model use the piece replaces worn or distorted plastic cups, reduces play at the centre shaft connection, and supports a more consistent drive characteristic during gear mesh and preload adjustments. The machined aluminium body delivers improved resistance to wear versus typical stock parts while keeping the correct shape for Fazer Mk2 FZ02 fitting.
Fitting advice: confirm seating against the existing centre shaft and secure with the original screws. After long service periods, lightly clean mating surfaces or trim minor burrs if necessary. Fit using appropriate hobby tools and do not over-tighten to avoid stressing gearbox components.
