This set contains front and rear wheel shafts intended for the KYOSHO Fazer Mk2 FZ02 chassis, supplied as two blue anodized aluminum shafts. They offer a metal replacement option where the factory pieces are plastic or lower-grade metal and are intended to improve wheel seating consistency.
Install these shafts when wheel retention and lateral play are factors in handling performance. Confirm your vehicle uses the FZ02 wheel shaft configuration before fitting to ensure compatibility with the referenced design.
Fitting is suitable for a hobby workshop: remove wheel and hub, swap the original shaft for the replacement, then reassemble and check wheel runout and bearing alignment. Use appropriate hex tools, avoid over-torquing, and recheck fasteners after initial runs to confirm secure seating.
