The GPM Aluminium Servo Horn is specified for the 23T spline output shaft and is compatible with Airtronics, Sanwa and equivalent servo systems. It is intended as a durable replacement or upgrade to refine steering input and maintain consistent control characteristics under use.
Manufactured from quality aluminium, the horn provides improved structural strength while keeping mass low. The geometry ensures a firm engagement on the spline, reducing unwanted play and contributing to crisper servo response for tuning and long term reliability.
