This centre shaft is specified for the Kyosho FW-06 platform under model code FW06-13 and is manufactured as a direct-fit replacement to preserve original driveline alignment. It is intended for routine service and chassis rebuilds where stock geometry must be retained.
Workshop recommendations for competitive tuners: verify spline fitment and coupling engagement, confirm concentricity of mating components, and inspect drive cups and dogbones for micro-wear before reassembly. Use measured torque settings during installation and rotate the driveline by hand to validate smooth operation and eliminate preload that can affect handling on the track.
Install this shaft when rebuilding or servicing FW-06 cars to restore correct driveline geometry and ensure predictable setup adjustments during tuning sessions.
