Mounting stay for TRF421X shock placement

This damper stay mount, identified as Tamiya 3451585 and linked to part code 42391 for the TRF421X, is an RC replacement/hop-up component that sets the shock mounting location on the chassis. It connects the shock towers to the damper assembly and is intended for use with TRF421X setups that follow the original mounting layout.

In use, the stay determines mounting geometry which alters shock angle, leverage and roll response. When installing this stay mount, keep the chassis' original mounting points and hardware to preserve alignment; the part is designed to match the TRF421X mounting architecture rather than change it.

Before fitting, confirm the part number (42391) against your chassis documentation and check mounting holes and fasteners for correct fit. Follow standard RC maintenance practice when inspecting thread condition and applying torque appropriate to your model's hardware.

This part is listed as Tamiya 3451585 and associates with TRF421X part code 42391, so it is meant for TRF421X mounting layouts. Verify against your chassis paperwork before ordering.
Remove the original stay, check that the mounting holes match the new part, transfer any original hardware where appropriate, and install hand-tight before final torquing. Confirm the shock angle visually before running.
Generally yes; reuse the chassis fasteners if they seat correctly. Inspect threads and replace any worn hardware to ensure a secure installation on the TRF421X.
Keep the original geometry when possible, check ride height and camber after fitting, and make small adjustments to shock position to fine tune roll and steering balance.
Obtain Tamiya spare parts from authorised dealers or official distributors and verify part numbers 3451585 / 42391 for correct compatibility with your TRF421X.
