Mini-Z MR-03 Compatible Rear Knuckle Arm Holder MZA031R/0 by GPM  [MZA031R/0]

Alloy rear knuckle holder for Mini-Z MR-03 style AWD

This alloy rear knuckle arm holder is supplied as an aftermarket replacement for Kyosho Mini-Z AWD platforms and is listed under part number MZA031R/0. It acts as the mounting point for the rear knuckle assembly on compatible Mini-Z AWD RC cars.

Replacing plastic knuckle mounts with an alloy unit gives a stronger mounting surface, which helps keep the rear axle aligned and improves geometry repeatability when altering suspension settings. The increased stiffness compared with stock parts aids tuning precision.

Installation calls for basic removal of the rear assembly to reach the knuckle arm mount, reuse of existing compatible fasteners, and careful torqueing of screws to preserve thread engagement and alignment. This component is intended for model use only on compatible Mini-Z AWD chassis.
