This aftermarket 15T horn is CNC-machined from 7075-T6 aluminum and intended for ARRMA Kraton and Outcast 1/5 scale 8S trucks. The straight-arm construction houses an internal spring to cushion impacts and lower shock feed-through to the servo. Three selectable tie-rod positions permit steering throw and endpoint tuning to refine handling. It is listed as a replacement for factory parts ARA340165 and ARA320553 and is compatible with the original and GXservo units rated 70KG, X100KG, X120KG, and X150KG as detailed by the source.
Built as an RC-scale replacement for 15T spline servos, the unit ships with mounting hardware and bearing components intended to allow direct fitment where spline and mount dimensions match the stock horn. Use the alternate mounting holes to adjust mechanical advantage for chassis setup or driving preference.
