Durability-focused damper stay for TRF421X

The component marked Tamiya 3451585, referenced with part code 42391 for the TRF421X, is an aftermarket replacement/hop-up piece that locates the shock on the chassis. It functions as the interface between shock towers and dampers and is designed for TRF421X style mounting layouts.

From a functional standpoint, the stay sets mounting geometry that influences shock angle, leverage and roll behaviour. When fitting the stay, retain the chassis' original mounting points and hardware to maintain alignment; the part is intended to match TRF421X architecture rather than alter it.

Prior to installation, confirm the 42391 part number against your chassis documentation and inspect the mounting holes and fasteners for proper seating. Carry out routine checks on thread condition and torque settings as part of standard RC maintenance to ensure long service life.

Yes. The listing ties 3451585 to part code 42391 for the TRF421X mounting layout, but always cross-check with your chassis paperwork to be certain.
Look for elongated holes, cracked edges and thread damage around mounting points. Regular inspection after track sessions helps catch fatigue before it leads to failure.
Reinforcement options depend on your chassis; use caution and keep geometry unchanged. For high-impact use, check compatible reinforcement parts or consult service guides rather than modifying the stay itself.
The supplier reference gives the part number and function but does not declare material composition. Refer to official Tamiya documentation or authorised parts information for material details.
Buy Tamiya spare parts from authorised retailers or official distributors and confirm you are ordering part 3451585 / 42391 for the correct TRF421X fitment.
