About this part

Exotek's Associated Aluminum HD Servo Horn has answered a long time call from Associated fans. This 25 tooth aluminum servo horn perfectly matches the geometry of the stock AE servo horn and features a clamping design that uses a heavy duty M2.5 screw to lock the horn down on the servo. This is the only clamping horn that matches the geometry of the stock servo horn! Now you have perfect fit and geometry for precise steering and durable lasting performance.

Features:
  • Perfect replacement for all Associated 1/10 vehicles
  • Compatible other 1/10 brand models- just check dimensions for compatibility
  • Polished and anodized in factory blue or black and laser etched for easy reference
  • Large M2.5 clamping screw included
  • Fits Futaba and all other 25 spline servos

Never really like this horn from the beginning. It would loosen up over a heat race every time. I eventually used some threadlock but then the cheap screw stripped out while trying to remove. Can't really use it now since there is no way of removing the screw. Lesson learned.

It need a metric ball end! It is not compatible with SC10.3 at all!

Works Great! Would definitely recommend to anyone that’s looking for a great quality part!

What reviewers say

Reviewers generally report that this 25-tooth blue aluminum servo horn fits their Futaba, Savox or ProTek servos and works well, with several saying it replaced a broken stock plastic horn without issue. One reviewer praised fit and installation on an AE B6.4 and another noted smooth steering without binding on a B5M Lite. Two reviewers gave low ratings: one said the horn loosened repeatedly during a heat race and that the included screw stripped when they tried to remove it after applying threadlock; the other said it lacks a metric ball end and is not compatible with the SC10.3. Reviews mention B5M, T5M, SC5M, and AE B6.4 vehicles. Overall ratings are high, but the sample is small and the negative reviews point to screw retention and compatibility concerns.

  • + Fits Futaba, Savox and ProTek servos
  • + Works well as a replacement for a broken stock horn
  • + Easy installation
  • + No binding during steering
  • − Screw loosens under heavy use
  • − Included screw can strip during removal
