Kyosho Mini-Z AWD Rear Knuckle Arm Holder for Tuning 0.6mm -0.4mm MZA031R-0406 by GPM  [MZA031R-0406]

Rear knuckle arm alloy holder for Mini-Z AWD

This GPM aftermarket alloy rear knuckle arm holder is a single-piece replacement for Kyosho Mini-Z AWD platforms, built to a steady 0.6mm thickness with a -0.4mm rear toe bias. It ships as 1 pcs and is intended to replace softer plastic mounts when a firmer rear end response is desired.

The item is a tuning component rather than a trim piece: alloy stiffness reduces pivot flex so toe settings remain more stable during repeated cornering. It is designed for Mini-Z AWD arrangements using MR-03 AWD style knuckles; confirm your chassis pattern before fitting.

Installation guidance: use OEM fasteners, ensure proper thread engagement and alignment, recheck toe after installation, and do not over-torque to avoid bearing or shaft issues. Quantity supplied: 1 pcs.
