Tamiya MF01X Rear Hub Knuckle Set MF022 by GPM  [MF022]

This aluminium rear knuckle arm is an aftermarket replacement made for the Tamiya MF01X and supplied as a 1pr set. It replaces the stock plastic knuckles to provide a stronger, more stable pivot for rear hubs during setup and running.

Fitting the metal knuckle changes rear steering geometry and stiffness versus the original parts, which helps when dialling in toe and camber under load or when you need a firmer anchor point for tuned suspension settings. The aluminium construction aims to reduce flex and deliver consistent alignment lap after lap.

Fitting is straightforward on MF01X layouts: remove the rear hub carriers and related fasteners, move bearings and pins from the original parts, then secure the new knuckle using the original hardware with thread locking as required. Confirm full range of suspension travel and wheel alignment after refit.
