ARRMA 1/5 Kraton/Outcast 7075 Alloy 15T Adjustable Servo Horn by GPM MAKX015TSH/N  [MAKX015TSH/N]

7075 Alloy 15T Adjustable Servo Horn

This aftermarket 15T servo horn is machined from 7075-T6 aluminum and is intended for 1/5 scale ARRMA Kraton and Outcast 8S series RC trucks. The arm combines a straight‑arm geometry with an internal spring feature to help absorb impact and reduce shock transmission to the servo. Three position holes allow tie‑rod length and steering throw adjustments to fine‑tune steering response and end‑point behavior. The item replaces factory part numbers ARA340165 and ARA320553 and is compatible only with the original servo and GXservo units rated 70KG, X100KG, X120KG, and X150KG as stated by the source.

The component is an RC‑scale part designed to work with 15T spline servos. It is supplied with mounting hardware and bearing components to fit as a direct replacement for the stock horn where spline and mounting dimensions match the original arrangement. Use the three-position holes to change mechanical advantage or to compensate for chassis geometry during setup.
