Refined steering with the Yokomo ZC-204317A servo horn

The Yokomo ZC-204317A Aluminium 17mm servo horn gives model drivers a firmer link between servo and steering. Made for Airtronics and KO servos, it uses a 23T spline and a 17mm arm length to help deliver precise inputs on both drift and off-road cars.

Performance-minded construction

This part is intended to transfer servo movement directly to the steering linkage, cutting down unwanted play. The aluminium construction adds strength and helps keep steering consistent during demanding runs.

Installation and compatibility overview

The horn is designed to mate with Sanwa and KO servo shaft splines and locates the pillow ball mounting hole 17mm from the servo output centre for reliable setup. That sizing makes it straightforward to fit to a variety of chassis arrangements.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Can I use this on a front-wheel drive style setup?

Yes. Any steering layout that accepts a 17mm horn and 23T spline can use this part, including front-wheel drive style linkages.

What servos are confirmed compatible?

It is specified for Airtronics and KO servos and fits Sanwa spline patterns as noted. Verify your servo uses a 23T spline for correct fit.

Should I change other steering parts when upgrading?

Consider checking ball cups and linkages for wear; a rigid horn will expose any loose or worn components that could affect steering precision.

Any advice for longer service life?

Keep the spline area clean, avoid overtightening the retaining screw, and inspect the horn periodically for signs of wear.

Will this change handling balance?

It can sharpen steering response; depending on your setup, you may need small trim or toe adjustments after fitting to regain your preferred balance.
