TAMIYA TRF 416 Aluminium Knuckle Arm by 3Racing 416-18/LB  [416-18/LB]

Aluminium knuckle arm for TRF 416

This aluminium knuckle arm is an RC-scale replacement part produced by 3Racing for the TAMIYA TRF 416 chassis, supplied under model 416-18/LB. It is intended as a direct-fit steering knuckle for use on TRF 416 models, offering a metal alternative that maintains geometry and mounting points consistent with the original knuckle design.

In practical setup terms the part serves two primary roles: it provides a stable mounting interface for the wheel hub and steering linkage, and it preserves suspension geometry during tuning. When swapped into a TRF 416, it helps keep steering inputs consistent while you adjust camber, toe, or shock settings, without changing how the chassis mounts the knuckle.

Installation notes: the knuckle is offered as a drop-in replacement for the TRF 416 knuckle arm and uses the chassis' existing mounting locations. Check your chassis manual for torque values and mounting order, and inspect linkages and wheel hex fit after installation to confirm proper alignment.
