25T Aluminum Servo Horns

This pack contains five orange anodized aluminum servo horns with a 25-tooth spline and M3 threads. They are designed for Futaba, Savox, Xcore and similar standard servos used in RC cars, trucks, buggies and airplanes. The hard aluminum construction replaces plastic arms for improved precision and durability. Each horn uses a split-clamp design secured by two steel bolts.

Split-clamp design with two steel bolts

The adjustable split-clamp tightens directly onto the servo output shaft using the two included steel bolts. This clamping method removes the play common with single-screw plastic horns. The rigid aluminum body does not flex under load, so steering input remains consistent during high-torque manoeuvres. No thermal, noise or electrical considerations apply to this mechanical component.

Five-piece set with dual hole centres

The package supplies five identical horns, providing spares for multiple models or quick replacement after impact. Each arm offers mounting holes at 20 and 24 millimetres from the spline centre, allowing linkage geometry to be tuned without buying additional parts. The 6 millimetre and 3 millimetre hole diameters suit common ball-stud and screw sizes.

Questions about this item

How do I install the 25T spline horn and which bolt step is often missed?

Slide the 25T spline onto the servo output, align the split-clamp, then thread both M3 bolts evenly; skipping the second bolt leaves the clamp loose and the horn can slip.

What maintenance will the aluminum horn and its steel bolts need over time?

Check the two M3 bolts for tightness after the first few runs and periodically thereafter; the anodized aluminum resists corrosion, so no lubrication or replacement schedule is required.

Which dimension limits steering geometry first on a long run?

The hole centers fixed at 20 and 24 mm from the servo output set the maximum throw; the 35 mm overall length and 6 mm thickness do not change under load.
