This 15T aftermarket servo horn is CNC machined from 7075-T6 aluminum for ARRMA Kraton and Outcast 1/5 scale 8S vehicles. The arm pairs a straight geometry with an internal spring element that helps absorb impacts and lessen shock transmission to the servo. Three position holes permit tie-rod length and steering throw changes to fine-tune steering response and end-point characteristics. The part replaces factory numbers ARA340165 and ARA320553 and is noted as compatible with the original servo and GXservo models rated 70KG, X100KG, X120KG, and X150KG in the source information.
Intended for 15T spline servos, the horn is provided with mounting hardware and bearing components so it fits where spline and mounting dimensions match the original. Use the selectable holes to alter mechanical advantage or adapt to chassis geometry during setup.

As a CNC 7075 alloy upgrade, this horn serves as a direct replacement that preserves servo compatibility while providing adjustable linkage positions and enhanced impact absorption for steering setups on 1/5 ARRMA trucks; follow fitment and torque guidance during installation.
