The JR-KFZ201-GU aluminium centre shaft cup joint is produced for the KYOSHO Fazer Mk2 FZ02 chassis as an aftermarket driveline component. It provides a metal alternative to the stock plastic cup to address premature wear and flex during regular use.
With an aluminium construction and gun-metal finish, the unit is intended to match the original mounting form while offering improved longevity. As a direct fit for the specified Fazer Mk2, it focuses on reliable mechanical alignment and extended intervals between part replacement.
Installation follows standard practice for Fazer Mk2 maintenance: remove the original cup joint and fit this aluminium unit using the existing hardware where compatible. After fitting, verify free rotation and correct mesh with neighbouring couplers and bearings.
Performance note: the aluminium cup joint alters drivetrain compliance compared to the original plastic piece, and many users select it for incremental durability gains and steadier driveline feedback during sustained running.
