This precision aluminium front upper arm is supplied as an aftermarket replacement compatible with the Kyosho Mini Inferno ST platform and designated MIF2054. It is supplied as a direct-fitting RC suspension part intended for repair or set-up changes rather than any real vehicle application.
The component uses aluminium alloy to increase stiffness over typical polymer arms, and the kit includes the necessary pins, E-clips and mounting screws for installation into the existing uprights. The arm will influence steering geometry and roll centre marginally, so it is useful when tuning toe, camber response and the front-end balance for competitive club running.
Installation follows standard procedure for Mini Inferno ST servicing: remove the original arm, transfer bearings or shims as needed, install the alloy arm into the upright and secure with the supplied pins and E-clips, then torque screws to an appropriate setting without over-tightening. After assembly, verify free suspension travel and confirm wheel alignment settings.
