Improved steering accuracy with Yokomo ZC-204317A

Hobby drivers seeking finer steering control will appreciate the Yokomo ZC-204317A Aluminum 17mm servo horn. Specifically made for Airtronics and KO servos, it features a 23T spline and a 17mm arm to help refine steering input on both drifting and off-road vehicles.

Reliable construction for sharper response

The Yokomo ZC-204317A transmits servo movement cleanly to the linkage, reducing slack and improving on-track feel. The aluminum build boosts durability and keeps steering feedback consistent during aggressive driving.

Compatibility notes and easy mounting

Designed to engage Sanwa and KO servo shaft splines securely, this horn keeps a precise 17mm distance from the output shaft to the pillow ball mounting hole for simple alignment. It adapts well to different chassis setups used in drift and rough-surface cars.
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.

How does this horn affect steering feel?

By offering a rigid connection and 17mm lever arm, it reduces flex between the servo and link, sharpening steering response.

Can I use it on a drift car and an off-road buggy?

Yes. The geometry and spline compatibility make it suitable for both drift and off-road applications where that arm length works.

What spline does it use?

It uses a 23T spline, matching many Airtronics and KO servo outputs. Confirm your servo spline count before fitting.

Any tips for fitting it cleanly?

Align the pillow ball hole carefully to avoid binding, and tighten the servo horn screw progressively to prevent misalignment.
