Kyosho Mini-Z AWD Alloy Rear Knuckle Arm Holder (Toe Out -0.4mm, Thick 0.6mm) by GPM MZA031R-0406  [MZA031R-0406]

Alloy rear knuckle arm holder for Mini-Z AWD

This GPM aftermarket part is a single-piece alloy rear knuckle arm holder made for Kyosho Mini-Z AWD platforms, finished to a consistent 0.6mm thickness and set to provide a -0.4mm toe out at the rear. It is supplied as 1 pcs and intended to replace the stock plastic mount where a stiffer alloy component is preferred for tighter control during cornering and consistent toe geometry under load.

The component's role is tuning-focused rather than cosmetic: by using an alloy holder you reduce flex at the knuckle pivot and help the rear suspension hold toe settings more predictably across repeated laps. This part is compatible with Mini-Z AWD layouts that use the MR-03 AWD style knuckle arrangement, but confirm fitment with your chassis before installation.

Installation notes: use the factory fasteners and pay attention to thread engagement and alignment, re-check toe after fitting, and avoid over-torqueing to prevent bearing or shaft damage. The holder is offered as a single replacement piece, supply count: 1 pcs.
