Keeping a TRF414M2 performing well means addressing worn suspension parts promptly. The Tamiya 3454077 Suspension Arm Block E is intended to replace degraded blocks and return the chassis to its designed behaviour.
Using the correct arm block helps reduce play at the suspension mount and keeps steering inputs consistent, which is important for lap-to-lap repeatability.
Replacement is straightforward and does not require chassis modification, making it suitable for routine servicing at home or at the track.
Keeping spare arm blocks available avoids long repair times and helps preserve the rest of the suspension by preventing run-to-failure scenarios.
