For TRF421 setups, the Tamiya 51743 TRF421 V set of upper and lower damper parts offers a quick way to replace fatigued suspension pieces. Fitting fresh damper components helps preserve predictable shock action when running on dirt, grass or mixed surfaces.
The kit contains both upper and lower pieces matched to the TRF421 chassis. Straight swap fitment reduces setup time and restores the intended damping behavior, which can improve consistency across different track conditions.
Work in a dust-free area and wipe parts clean before assembly to avoid abrasive contamination. Ensure parts are seated correctly during reassembly to prevent binding and premature wear when tackling rough terrain.
