Kyosho IFW610C Aluminum Servo Horn Compatible with MP10 and 18.5mm SANWA/KO Splines  [KY-IFW610C]

Product Summary and Fitment Notes

This Kyosho IFW610C aluminum steering servo horn serves as a replacement interface for splined servos, providing a rigid connection between the servo output and the steering linkage on 1/10 touring platforms such as the MP10.

The part is intended for servos that use 18.5mm splined output in SANWA and KO formats. Always confirm your servo spline type before fitting. The horn is a mechanical component used to fine tune steering throw, centring and end points through physical linkage geometry rather than electronic adjustments.

For installation, remove the original horn from the servo spline, seat the IFW610C onto the servo output splines, and secure it using the original retaining screw or servo saver where applicable. Inspect for full spline engagement and minimal play. Reuse stock linkages or adjustable turnbuckles to restore tie-rod length and toe settings, and use correct hex drivers to avoid stripping small fasteners.

On handling and setup, an aluminum horn reduces flex at the linkage interface, which can stabilise steering ratios under load and allow more precise mechanical endpoint adjustment. Changes will affect mechanical feedback to the driver rather than altering servo electronics, and you should verify there is no binding through full suspension travel.
