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

Front lower arm shaft compatible with TRF418

This front lower arm shaft is supplied as an RC replacement for installation in the front lower arm positions of Tamiya TRF418 chassis types. Arrowmax crafted the AM-417-BC10 shafts from spring steel and applied a titanium nitride (TiN) coating to reduce surface drag and improve wear resistance.

Being a lower arm shaft, the part plays a direct role in suspension articulation and in how smoothly the lower arm pivots under load. The TiN coating helps cut metal-on-metal drag where the shaft contacts the arm or bushings, preserving consistent movement during repeated use. The listing specifies 2 pcs for the front lower arm spots.

Installation is direct for common TRF418 arm mounts, but confirm clearance and fit with your existing arms and bushings before finalising assembly. Perform routine inspections to check the coating and replace shafts if you detect heavy wear.
