Key Features
- Lightweight and strong aluminium construction — The aluminium material provides the perfect balance between weight savings and structural integrity, allowing your servo to operate more efficiently whilst maintaining the rigidity needed for precise steering control and durability during aggressive driving.
- Precision machined design — Each servo horn is manufactured to exacting tolerances, ensuring a perfect fit to your Spektrum servo splines without wobble or slipping, which is critical for maintaining consistent steering geometry and preventing unpredictable handling behaviour on the track or bash course.
- Professional black anodised finish — The hard anodised black coating provides superior durability and corrosion resistance, protecting the aluminium substrate from weather exposure, dirt, mud, and the wear that comes with regular RC use in British weather conditions.
- Laser-etched Spektrum branding — The precision laser etching of the Spektrum logo adds visual appeal whilst also serving as a durable identifier that won't fade or peel off during extended use, maintaining the professional appearance of your RC car.
- 23-tooth servo spline compatibility — This servo horn is specifically engineered with a 23T spline configuration to match Spektrum servo specifications exactly, guaranteeing a secure, slip-free connection that eliminates the risk of steering linkage failure during intense driving sessions.

Frequently Asked Questions
- What ARRMA models is the 23T Spektrum servo horn compatible with? — This servo horn is compatible with a comprehensive range of ARRMA vehicles including the 1/7 Felony 6S AVC, Fireteam 6S, Infraction 6S AVC, Limitless 120 8S AVC, Limitless 6S, Mojave 6S variants, and the extensive 1/8 range including Kraton 6S, Notorious 6S, Outcast 6S EXB AVC, Talion 6S EXB AVC, and Typhon 6S models in various configurations. Check the full fitment list to confirm your specific model.
- Will this servo horn fit my Spektrum servo? — Yes, this servo horn is specifically engineered with a 23-tooth spline configuration that matches the specifications of Spektrum servos precisely. The precision machining ensures a perfect fit without any play or wobble, which is critical for maintaining accurate steering response.
- Is aluminium strong enough for off-road RC use? — Absolutely. The premium-grade aluminium used in this servo horn offers an excellent strength-to-weight ratio. When combined with precision machining and the anodised finish, it provides durability comparable to steel whilst maintaining the weight savings that improve overall vehicle performance and servo efficiency.
- Can I use this on my ready-to-run RC car? — Yes, this servo horn is designed as a direct replacement for damaged or worn steering components on ready-to-run ARRMA RC cars. If your servo horn has become stripped, bent, or damaged during use, this genuine ARRMA replacement will restore your steering system to factory specifications.
- What makes the anodised finish important? — The black anodised finish is not purely cosmetic. Hard anodising creates a protective oxide layer that significantly improves corrosion resistance, extends the lifespan of the aluminium component, and prevents oxidation that could otherwise weaken the material over time or affect the precision fit to your servo splines.
- Is this suitable for high-performance RC racing? — Yes, this is a precision-engineered component suitable for both casual RC car use and competitive racing. The precision machining and rigid construction make it ideal for drivers seeking consistency and reliability in their steering response, whether you're competing in local UK RC racing events or enjoying weekend bashing.
