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

Front lower arm shaft for TRF418 layouts

This front lower arm shaft is an RC replacement tailored for the front lower arm mounting points on Tamiya TRF418 chassis. Arrowmax manufactured the AM-417-BC10 shafts from spring steel and finished them with a titanium nitride (TiN) coating to lower contact friction and enhance wear resistance.

The shaft influences suspension articulation and the smooth pivoting of the lower arm under load. The TiN coating reduces metal-on-metal friction at the contact points with arms or bushings, helping preserve consistent movement across multiple sessions. The listing indicates the item is supplied as 2 pcs for the front lower arm positions.

Fitting is simple for standard TRF418 arm mounts, but confirm fitment and clearance against your current arms and bushings before final assembly. Carry out periodic inspections to monitor coating condition and replace shafts if you observe significant wear.
