This is a ProTek R/C Aluminum Servo Horn, and is intended for use with any servo that uses a 25 tooth spline output shaft. This extremely tough servo-horn has been machined from a solid block of aluminum for incredible precision, rigidity and durability. This horn features a 3mm thick arm for durability, has 19mm hole spacing and uses 3mm hardware to suit the geometry and hardware requirements of most vehicles.


  • 19mm hole spacing (measured from output shaft screw hole, to linkage rod holes, center to center)
  • 3mm thick arm
  • 27.25mm Overall length
  • Linkage holes threaded for 3mm hardware
  • 25T Spline Futaba/Orion/Savox/ProTek Output Shaft

Note: Due to manufacturer tolerances, this servo horn may be a tight fit with certain servo brands.

To tight of a fit, needed to use the screw the fully seat on the servo and then when I needed to remove it I had to use locking pliers. Won’t buy this style again.

This new ProTek RC servo horn looks perfect in my 1/8 and 1/10 vehicles. The black finish accents the new black ProTek servos perfect. Great product, and one of my favorites.

ProTek RC Aluminum Servo Horn (Black) (25T-Futaba/Orion/Savox/ProTek)
Horn works well. no major complaints; Splines are a little tight, need to use a touch of ant seize to be able to remove in the future without scratching servo. Loosens up over time. Will buy again.

ProTek RC Aluminum Servo Horn (Black) (25T-Futaba/Orion/Savox/ProTek)
This servo horn did not fit my my 25T Savox servo at all. The teeth were not formed very well, they looked stamped versus machined. It was way too tight and I was afraid to push the horn on any tighter for fear of damaging the servo.

ProTek RC Aluminum Servo Horn (Black) (25T-Futaba/Orion/Savox/ProTek)
Got one of these. The fit on the servo spline is super loose. It wobbles all over the place until screwed tight and then if your torque it the fit is off. Tried it on a futaba servo and radiopost with the same outcome. Maybe they got a bad batch or something but I am not happy with mine.
They did issue a refund for it but I doubt I will purchase another one.

Badass little servo horn, put this in my Durango DEX210 because it's a tight fit, it works great and looks the part
