This aluminium rear knuckle arm is a dedicated RC replacement for Tamiya M1025 Hummer installations, model HM1022. Specified as an aftermarket component, it replaces factory plastic knuckles to provide a firmer, more consistent mounting location for suspension linkages on TA-01 and TA-02 compatible chassis.
Intended use covers setup work and routine maintenance where a more repeatable knuckle mounting point is required. After fitting, verify wheel bearing preload and linkage angles to restore correct suspension geometry and ensure predictable handling.
Fitting procedure: remove the stock knuckle, transfer bearings and fasteners as needed, install the aluminium knuckle in the original orientation, and confirm axle and hub hardware are correctly torqued before operation.
A practical, precision-focused aluminium knuckle for model builders tuning suspension response on M1025 Hummer and compatible Tamiya chassis.
