This precision 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 forms the rear knuckle mounting interface for compatible Mini-Z AWD models.
The alloy construction provides a firmer mounting surface than plastic, assisting in maintaining rear axle alignment and improving geometry repeatability during tuning. The design focuses on dimensional stability to support consistent setup changes.
Installation requires rear-end access on the Mini-Z AWD chassis, reuse of appropriate fasteners, and controlled torque on mounting screws to protect thread engagement and alignment. Intended for hobbyist upgrade use on compatible Mini-Z AWD models only.
