This adjustable servo arm is a 6061 T6 aluminum, model-scale component intended for the TRAXXAS TRX4 Trail Crawler and is supplied as a 7pcs set. The straight-arm design delivers consistent steering inputs and the lasered hole scale makes setting the 20-25mm pitch quick and repeatable for different servos and linkages.
Installation is straightforward: remove the original horn, fit the new arm to the servo spline, and secure with the included screws. The selectable hole pattern is useful for tuning steering throw and mechanical advantage without needing to modify other parts, letting you refine handling on trail courses.
