This is a ProTek R/C Aluminum Double-Sided Clamp Lock 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 clamp type design that grips the servo’s output shaft with enough force that even if the retainer screw comes loose, the horn will remain in place, increasing your chances of finishing the race! Additionally, the arm is 2mm thick, has 19.75mm & 24.25mm hole spacing and uses 3mm hardware to suit the geometry and hardware requirements of most vehicles.

Great fit. Clamps tight to my Savox 1257tg. Using in a Losi 8ight-T 2.0. Needed to ream the holes some so the stock Losi hardware would fit, but thats it. Nice piece. Will also install on my 8ight 2.0 EU.
