The Tamiya 7684002 crank shaft is intended as a direct replacement part for compatible models, helping to restore drivetrain integrity after wear or impact. Using an original Tamiya component keeps tolerances and fitment predictable.
Designed to match Tamiya chassis specifications, the 7684002 crank shaft supports a range of models where the part number is specified. Confirm compatibility against your model's parts diagram before purchase.
When replacing the crank shaft, inspect adjoining components like bearings and couplings to ensure the whole driveline is in good order. Correct installation of the 7684002 reduces vibration and improves drivetrain response.
