Tamiya MF01X Rear Knuckle Arm MF022 by GPM  [MF022]

This aluminium rear knuckle arm is an aftermarket replacement part made for Tamiya MF01X platforms and sold as a 1pr set. It is intended to replace the stock plastic rear steering knuckles to provide a more consistent mounting point during setup and regular use.

The knuckle alters rear steering geometry and stiffness compared with the original plastic pieces, helping you refine toe and camber behaviour under load and achieve a firmer pivot for tuned suspension setups. Its metal construction aims to give repeatable alignment and improved resistance to wear during track use.

Installation follows standard rear knuckle swap procedures on MF01X layouts: remove the rear hub carriers and fasteners, transfer bearings or pins from the original parts, then fit the aluminium knuckle with the original hardware and thread locker where recommended. Always confirm fitment on your MF01X chassis and recheck suspension travel and wheel alignment after installation.
