Precision alloy rear knuckle arm holder for MR-03 AWD

This single-piece alloy rear knuckle arm holder from GPM is specified for Kyosho Mini-Z AWD platforms and is finished to a uniform 0.6mm thickness with a -0.4mm rear toe setting. Supplied as 1 pcs, the component is intended as a stiffer replacement for the stock plastic mount to reduce pivot flex and improve repeatable toe geometry under dynamic loads.

As an upgrade component, the holder focuses on predictable suspension behaviour: the alloy reduces movement at the knuckle pivot so toe changes remain consistent through multiple laps. Confirm MR-03 AWD knuckle compatibility with your chassis before fitting.

Installation notes: retain factory fasteners, ensure correct thread engagement and alignment, verify toe after assembly, and avoid over-torqueing to prevent bearing or shaft damage. Supplied quantity: 1 pcs.

What precision benefits does an alloy holder provide?

An alloy holder reduces compliance at the knuckle pivot compared to plastic, which helps maintain set toe angles under load and improves repeatability in lap-to-lap tuning checks.

Is the MZA031R-0406 a direct replacement for stock parts?

The part is designed for MR-03 AWD style knuckle arrangements; while it replaces the plastic mount in many MR-03 AWD builds, verify the knuckle mounting pattern on your chassis before installation.

Any assembly precautions for longevity?

Use factory fasteners with correct torque, check alignment and thread engagement, and perform a post-fit toe check. Avoid sharp impacts that could deform the alloy holder.
