Tamiya MF01X Rear Knuckle Arm by GPM MF022  [MF022]

This aluminium rear knuckle arm is an aftermarket replacement part produced for Tamiya MF01X platforms by GPM, sold as a 1pr set. It is an RC-scale component intended to replace stock rear steering knuckles and to support suspension and steering setup changes on model cars.

The part's role is to change the rear steering geometry and stiffness characteristics compared to the original plastic pieces. That makes it useful when adjusting toe, camber behavior under load, or when you want a firmer mounting point for the rear hub on a tuned MF01X chassis. The component is presented as a durable aluminium alternative while remaining specific to the MF01X layout and mounting points.

Installation is typical for rear knuckle swaps on MF01X layouts: remove the rear hub carriers and associated fasteners, transfer any bearings or pins from the original parts, then secure the aluminium knuckle with the original hardware and recommended thread locking practices where applicable. Because this is an RC accessory, confirm fitment on your MF01X chassis before final assembly and check suspension travel and wheel alignment after installation.
