Owners of the TRF421 chassis will find the Tamiya 51743 TRF421 V upper and lower damper components useful for routine maintenance and repairs. These parts help maintain steady shock response and reduce variability when driving over rough layouts and loose surfaces.
The package supplies both top and bottom damper elements tailored to the TRF421 geometry. Their direct compatibility means you can swap them in without changing other shock internals, helping you keep consistent damping characteristics across sessions.
Clean threads and mounting faces before installation and inspect for debris that could hinder travel. Careful assembly and correct torque will preserve the shock stroke and prevent binding when running on looser tracks or bumpy courses.
