This anodized blue aluminium center shaft cup joint is a hop-up replacement designed for the Kyosho Fazer Mk2 FZ02 driveline. It strengthens the connection where the driveshaft meets the centre shaft, helping to reduce unwanted movement that can blur steering and throttle response.
Made from anodized blue aluminum, the part provides consistent geometry and improved wear characteristics to support predictable driveline behavior during tuning and setup changes. It is often used when fine-tuning driveline alignment or upgrading from plastic parts for more stable long-term performance.
Fitting is typical of on-road center drive service: detach the centre driveshaft, inspect bearing and mating surfaces, move or replace any retaining hardware, and install the new cup ensuring alignment and free rotation before securing. Run the drivetrain to confirm smooth operation and absence of binding.
