The plastic servo horn is the weakest link in most steering setups — it flexes under load, blurring your steering precision, and one hard hit can strip it at the spline. Absima's 3-in-1 aluminium horn is the classic fix: CNC alloy in place of flex, machined 25-tooth splines that seat solidly, and a clever two-piece, double-sided design that lets you arrange the arms to suit your installation rather than the other way around.

Fits the 25T Standard

The 25-tooth spline is the near-universal standard for full-size RC servos, and Absima confirms fitment for Absima, Savöx, Futaba, Bluebird, ThunderTiger and Spektrum servos — in practice, any servo on the standard 25T spline. If your servo's spec sheet says 25T, this fits. (Running a Sanwa/KO servo? Those are typically 23T — check your spline count before ordering; it's printed in every servo's specifications.)

The 3-in-1 Design, Decoded

Rather than a fixed arm, this is a two-piece, double-sided horn: arms of 43mm and 40mm that can be arranged around the spline mount to give single-arm, double-arm or offset configurations from the one package. That flexibility matters most on crawlers and customs, where steering geometry and linkage clearance vary build to build — one horn covers the setups that would otherwise need a drawer full of fixed arms.

Why Alloy

Aluminium at the servo horn does two jobs plastic can't: it removes the flex between servo and linkage, so every degree the servo moves arrives at the wheels, and it survives the impacts that strip plastic splines — the classic trail-day ender. It's the standard first upgrade on steering servos, particularly on crawlers where steering loads are highest, and the gunmetal anodising looks the part doing it.
