Tamiya TRF418 Front Lower Arm Shaft Upgrade, Spring Steel TiN - Arrowmax AM-417-BC10  [AM-417-BC10]

Replacement front lower arm shaft for TRF418

This front lower arm shaft is an RC-scale replacement made to install at the front lower arm locations on Tamiya TRF418 chassis layouts. Arrowmax produced the AM-417-BC10 shafts from spring steel and applied a titanium nitride (TiN) coating to lower surface friction and boost wear resistance.

As a front lower arm shaft, this component affects suspension articulation and the smoothness of lower arm rotation under load. The TiN finish cuts metal-on-metal drag where the shaft contacts arms or bushings, helping the suspension keep consistent movement over repeated runs. The listing supplies the item as 2 pcs suitable for front lower arm positions.

Fitment is straightforward for standard TRF418 arm mounts, but always check clearance and alignment with your current arms and bushings before final assembly. Perform routine inspections to ensure the coating remains intact and swap shafts if you spot excessive wear.
