KC10 Steering Horn Upgrade for 25T Splines - CL015 by Kyosho  [KY-CL015]

Aluminum Horn Designed for KC10

This AL servo horn acts as a replacement component suited to KC10 on-road 1/10 setups, functioning as the mechanical link between the servo output and steering linkage. It creates a stable connection point that influences steering throw and immediate mechanical response.

Built as a single-piece aluminum arm rather than a cosmetic item, the unit replaces plastic stock arms to reduce play at the servo output and maintain consistent input response while tuning. As with other RC parts, confirm that the horn matches the servo spline profile and that there is sufficient clearance to adjacent steering rods and suspension parts.

For installation: remove the existing horn from the servo, align the splines and fit the AL horn, then secure it with the original mounting screw(s). After installation, cycle the steering to check for binding on the KC10 steering geometry and make tie-rod adjustments as required to return the system to neutral alignment.

Tuning applications: using a rigid aluminum horn gives a firmer mounting point for steering geometry adjustments and endpoint tuning. The reduced flex under load helps preserve steering ratios during cornering and braking on smooth surfaces.

If you are servicing or fine-tuning a KC10-based on-road model, this horn serves as a practical, serviceable upgrade to improve servo interface consistency.
