Overview
The ARRMA Servo Horn 25T Z-ARA340198 is an essential replacement or upgrade component for RC enthusiasts across the UK who demand precision steering and reliable performance in their radio controlled cars. Whether you're a seasoned competitor running your RC buggy or truck at the track, or a weekend basher pushing your ready to run RC through challenging terrain, a quality servo horn is absolutely critical to maintaining accurate steering response and vehicle control. This black anodised aluminium servo horn is engineered to provide a strong and secure connection from your vehicle servo to your steering linkages, ensuring that every input from your RC radio transmitter translates precisely into steering movement.
Built with the exacting standards ARRMA is renowned for, this servo horn combines lightweight aluminium construction with precision engineering to deliver the performance and durability that serious RC car UK enthusiasts expect. The 25-tooth spline is specifically designed to fit a wide range of ARRMA vehicles and compatible servo systems, making this a versatile upgrade component that delivers excellent value whether you're maintaining an existing setup or fine-tuning your RC performance. The dogleg design provides additional clearance and flexibility in servo mounting configurations, allowing builders to optimise their steering geometry for maximum responsiveness and control.
If you're searching for a high-quality servo horn for your RC model car in the UK, this ARRMA component offers professional-grade construction at an accessible price point. The combination of precision machining, durable anodised finish, and proven ARRMA design makes this servo horn an ideal choice for anyone serious about maintaining or upgrading their RC vehicle's steering system.
Key Features
- Black Anodised Aluminium Construction — The servo horn is crafted from lightweight yet rigid aluminium that has been black anodised for a professional appearance whilst providing increased durability and corrosion resistance, ensuring your servo horn maintains its performance and looks even after extended use in outdoor RC environments across the UK.
- 25-Tooth Spline Design — The 25T servo spline is engineered for compatibility with a wide range of ARRMA servo systems and other compatible servo brands, providing a secure and accurate fit that ensures reliable steering performance without slippage or binding.
- Precision Machined for Accurate Fit — Every servo horn is precision machined to exacting tolerances, guaranteeing an accurate fit to servo splines without play or movement that could compromise steering accuracy or introduce dead zones into your RC car's steering response.
- Dogleg Design for Additional Clearance — The innovative dogleg configuration provides extra clearance between the servo horn and surrounding chassis components, allowing more flexible servo mounting options and helping to prevent interference with other parts of your RC vehicle's steering system.
- Laser Etched for Cool Looks — The servo horn features laser etching that adds visual appeal whilst serving a practical purpose, ensuring the component maintains its aesthetic quality and professional appearance throughout its service life.
- Lightweight and Strong Construction — The aluminium material delivers an excellent strength-to-weight ratio, ensuring your servo horn contributes minimal unsprung mass to your RC vehicle whilst maintaining the rigidity needed for precise, responsive steering control.
- Efficient Servo Operation — By combining low mass with high rigidity, this servo horn enables your servo to operate at peak efficiency, reducing unnecessary strain on your servo motor and helping to preserve servo lifespan whilst delivering consistent steering performance.
Technical Performance
The ARRMA Servo Horn 25T is engineered from premium black anodised aluminium, a material choice that reflects ARRMA's commitment to quality and performance. The anodised finish not only provides the striking black appearance that looks great on any RC car, but also delivers genuine functional benefits including corrosion resistance and durability that survives the demanding conditions of regular RC driving. Whether you're running your RC buggy through dusty off-road terrain, splashing through wet grass, or basking in intense sunlight at the track, the anodised finish protects the underlying aluminium from oxidation and wear. The precision machining ensures that the spline bore and engagement surfaces are manufactured to tight tolerances, eliminating the play or looseness that could introduce inaccuracy into your steering response. The 25-tooth spline configuration is a widely used standard in the RC industry, meaning this servo horn offers broad compatibility with ARRMA vehicles and many compatible servo systems from other manufacturers. The dogleg design is particularly clever from an engineering perspective, as it allows the horn arm to extend further from the servo centreline without creating interference issues, effectively lengthening the steering arm lever and providing better mechanical advantage for precise steering control. The lightweight aluminium construction means this component adds minimal rotational inertia to your servo system, allowing faster steering response times and reducing the electrical demands on your servo motor. This efficiency translates directly to better steering feel, longer servo lifespan, and more responsive handling in your ready to run RC or custom-built vehicle.

Frequently Asked Questions
- Will this servo horn fit my ARRMA RC car? — The 25-tooth spline design is compatible with a wide range of ARRMA vehicles and other RC models equipped with standard 25T servo splines. We recommend checking your vehicle's specification sheet or consulting with our expert team at RC Model Shop to confirm compatibility with your specific model before purchasing.
- What makes a quality servo horn important for RC performance? — Your servo horn is the critical link between your servo motor and your vehicle's steering system, translating the servo's rotational movement into precise steering input. A precision-engineered servo horn like this ARRMA component ensures that your steering response is accurate and immediate, without play, binding, or dead zones that could compromise your RC car's handling and control.
- Why is the dogleg design beneficial? — The dogleg configuration provides additional clearance between the servo horn and surrounding chassis components, allowing for more flexible servo mounting options and helping prevent interference with other steering system parts. This design also effectively increases the mechanical advantage of your steering arm, delivering more precise control with less servo movement.
- Is black anodised aluminium better than other materials? — Yes, black anodised aluminium offers an excellent combination of properties for RC servo horns. Aluminium is significantly lighter than steel or brass alternatives, reducing unsprung weight and improving steering response speed. The anodised finish provides genuine corrosion resistance and durability, ensuring your servo horn maintains its performance and appearance through regular UK outdoor RC driving.
- Can I use this servo horn as a replacement for a damaged original? — Absolutely. This servo horn serves as an excellent replacement component if your original has become worn, damaged, or stripped. The precision machining ensures it will fit and function just as well as the original equipment.
- Is this suitable for beginners? — Yes, whilst servo horns are technical components, this ARRMA servo horn is straightforward to install once you understand basic RC vehicle assembly. Beginners working on their first RC car should find installation well within their capabilities, especially with guidance from our experienced RC Model Shop team.
