Tamiya M03M Precision Aluminium Front Knuckle Arms M03M-06/LB by 3Racing  [M03M-06/LB]

Precision machined aluminium knuckles for M03M

This aluminium front knuckle arm set is an engineered upgrade for the Tamiya M03M chassis, intended to decrease steering assembly compliance. The light blue finish provides a clear service indicator while the aluminium construction increases stiffness where plastic parts typically flex, yielding more consistent steering geometry under load.

Compatibility and interfaces: confirm M03M platform compatibility before installation. These knuckles are designed to replace the OEM front knuckle arms and interface with standard M03M wheel hubs and steering linkages. Verify mounting bore alignment and hub seating prior to final assembly to ensure correct pre-load and running clearance.

Installation and setup: remove front hubs and steering links, install the aluminium arms using original fasteners when appropriate, and inspect for binding across the full travel of the suspension. Check servo horn and driveshaft clearances and make incremental turnbuckle adjustments to maintain target toe and steering centre. Torque fasteners to recommended values to avoid play without over-stressing components.

Tuning considerations: aluminium knuckles reduce elastic deflection in the steering path which sharpens initial steering response and helps maintain toe under lateral load. This part benefits setups targeting faster turn-in or firmer front suspension rates; run controlled test laps to document changes and adjust link geometry as required.
